RefTeX is a package for managing Labels, References, Citations and index entries with GNU Emacs.
Don't be discouraged by the size of this manual, which covers RefTeX in great depth. All you need to know to use RefTeX can be summarized on two pages (see RefTeX in a Nutshell). You can go back later to other parts of this document when needed.

RefTeX is a specialized package for support of labels,
references, citations, and the index in LaTeX. RefTeX wraps
itself round 4 LaTeX macros: \label, \ref, \cite,
and \index. Using these macros usually requires looking up
different parts of the document and searching through BibTeX database
files. RefTeX automates these time–consuming tasks almost
entirely. It also provides functions to display the structure of a
document and to move around in this structure quickly.
See Imprint, for information about who to contact for help, bug reports or suggestions.
RefTeX is bundled and pre–installed with Emacs since version 20.2. It was also bundled and pre–installed with XEmacs 19.16–20.x. XEmacs 21.x users want to install the corresponding plug-in package which is available from the XEmacs ftp site. See the XEmacs 21.x documentation on package installation for details.
Users of earlier Emacs distributions (including Emacs 19) can get a copy of the RefTeX distribution from the maintainers web-page. See Imprint, for more information.
RefTeX needs to access all files which are part of a multifile
document, and the BibTeX database files requested by the
\bibliography command. To find these files, RefTeX will
require a search path, i.e. a list of directories to check. Normally
this list is stored in the environment variables TEXINPUTS and
BIBINPUTS which are also used by RefTeX. However, on some
systems these variables do not contain the full search path. If
RefTeX does not work for you because it cannot find some files,
read Finding Files.
To turn RefTeX Mode on and off in a particular buffer, use M-x reftex-mode. To turn on RefTeX Mode for all LaTeX files, add the following lines to your .emacs file:
(add-hook 'LaTeX-mode-hook 'turn-on-reftex) ; with AUCTeX LaTeX mode
(add-hook 'latex-mode-hook 'turn-on-reftex) ; with Emacs latex mode
reftex-toc) will show
a table of contents of the document. This buffer can display sections,
labels and index entries defined in the document. From the buffer, you
can jump quickly to every part of your document. Press ? to get
help.
reftex-label-alist).
reftex-label) to insert a label at point.
RefTeX will either
reftex-insert-label-flags.
reftex-reference). This shows an outline of the document with
all labels of a certain type (figure, equation,...) and some label
context. Selecting a label inserts a \ref{label} macro
into the original buffer.
reftex-citation) will let you specify a
regular expression to search in current BibTeX database files (as
specified in the \bibliography command) and pull out a list of
matches for you to choose from. The list is formatted and
sorted. The selected article is referenced as `\cite{key}'
(see the variable reftex-cite-format if you want to insert
different macros).
reftex-index-macros). Multiple indices
are supported.
reftex-index-selection-or-word). The default macro
reftex-index-default-macro will be used. For a more complex entry
type C-c < (reftex-index), select any of the index macros
and enter the arguments with completion.
reftex-index-phrase-selection-or-word) to add
the current word or selection to a special index phrase file.
RefTeX can later search the document for occurrences of these
phrases and let you interactively index the matches.
reftex-display-index). From that buffer you can check and edit
all entries.
\label, \ref, \cite, \bibitem,
\index, and variations) or inside a BibTeX database entry, you
can press C-c & (reftex-view-crossref) to display
corresponding locations in the document and associated BibTeX database
files. \cite or \ref and no other
message occupies the echo area, information about the citation or label
will automatically be displayed in the echo area.
TeX-master or tex-main-file pointing to the
master file. RefTeX provides cross-referencing information from
all parts of the document, and across document borders
(xr.sty).
reftex-label and
reftex-index are used. To enforce reparsing, call any of the
commands described above with a raw C-u prefix, or press the
r key in the label selection buffer, the table of contents
buffer, or the index buffer.
reftex-plug-into-AUCTeX). AUCTeX
contains style files which trigger appropriate settings in
RefTeX, so that for many of the popular LaTeX packages no
additional customizations will be necessary.
(setq reftex-plug-into-AUCTeX t)
To make your own LaTeX macro definitions known to RefTeX, customize the variables
reftex-label-alist(for label macros/environments)reftex-section-levels(for sectioning commands)reftex-cite-format(for\cite-like macros)reftex-index-macros(for\index-like macros)reftex-index-default-macro(to set the default macro)
If you have a large number of macros defined, you may want to write an AUCTeX style file to support them with both AUCTeX and RefTeX.
Pressing the keys C-c = pops up a buffer showing the table of contents of the document. By default, this *toc* buffer shows only the sections of a document. Using the l and i keys you can display all labels and index entries defined in the document as well.
With the cursor in any of the lines denoting a location in the document, simple key strokes will display the corresponding part in another window, jump to that location, or perform other actions.
Here is a list of special commands in the *toc* buffer. A summary of this information is always available by pressing ?.
reftex-toc (C-c =) was
called.
reftex-highlight-selection, Options (Fontification).
reftex-toc-follow-mode. Note that only context in files already
visited is shown. RefTeX will not visit a file just for follow
mode. See, however, the variable
reftex-revisit-to-follow.
reftex-toc was last called.
\section to
\chapter, \subsection to \section etc. If there is
an active region, all sections in the region will be promoted, including
the one at point. To avoid mistakes, RefTeX requires a fresh
document scan before executing this command - if necessary, it will
automatically do this scan and ask the user to repeat the promotion
command.
\chapter to \section etc. If there is an active
region, all sections in the region will be demoted, including the one at
point.
reftex-toc was last called.
reftex-toc was last called.
reftex-toc-max-level.
reftex-toc-include-file-boundaries.
reftex-toc-include-labels. When called with a prefix argument,
RefTeX will prompt for a label type and include only labels of
the selected type in the *toc* buffer. The mode line `L<>'
indicator shows which labels are included.
reftex-toc-include-index-entries. When called with a prefix
argument, RefTeX will prompt for a specific index and include
only entries in the selected index in the *toc* buffer. The mode
line `I<>' indicator shows which index is used.
reftex-toc-include-context.
reftex-enable-partial-scans is non-nil, rescan only the file this
location is defined in, not the entire document.
xr package (see xr (LaTeX package)), RefTeX will switch to one of the external
documents.
reftex-auto-recenter-toc.
In order to define additional commands for the *toc* buffer, the
keymap reftex-toc-map may be used.
If you call reftex-toc while the *toc* buffer already
exists, the cursor will immediately jump to the right place, i.e. the
section from which reftex-toc was called will be highlighted.
The command C-c - (reftex-toc-recenter) will only redisplay
the *toc* buffer and highlight the correct line without actually
selecting the *toc* window. This can be useful to quickly find
out where in the document you currently are. You can also automate this
by asking RefTeX to keep track of your current editing position in the
TOC. The TOC window will then be updated whenever you stop typing for
more than reftex-idle-time seconds. By default this works only
with the dedicated *TOC* frame. But you can also force automatic
recentering of the TOC window on the current frame with
(setq reftex-auto-recenter-toc t)
The section macros recognized by RefTeX are all LaTeX section
macros (from \part to \subsubparagraph) and the commands
\addchap and \addsec from the KOMA-Script classes.
Additional macros can be configured with the variable
reftex-section-levels. It is also possible to add certain LaTeX
environments to the table of contents. This is probably only useful for
theorem-like environments. See Defining Label Environments, for an
example.
LaTeX provides a powerful mechanism to deal with cross–references in a document. When writing a document, any part of it can be marked with a label, like `\label{mark}'. LaTeX records the current value of a certain counter when a label is defined. Later references to this label (like `\ref{mark}') will produce the recorded value of the counter.
Labels can be used to mark sections, figures, tables, equations, footnotes, items in enumerate lists etc. LaTeX is context sensitive in doing this: A label defined in a figure environment automatically records the figure counter, not the section counter.
Several different environments can share a common counter and therefore
a common label category. E.g. labels in both equation and
eqnarray environments record the value of the same counter - the
equation counter.
In order to create a label in a LaTeX document, press C-c (
(reftex-label). Just like LaTeX, RefTeX is context sensitive
and will figure out the environment it currently is in and adapt the
label to that environment. A label usually consists of a short prefix
indicating the type of the label and a unique mark. RefTeX has
3 different modes to create this mark.
reftex-label
anyway is that RefTeX will know that a new label has been defined.
It will then not be necessary to rescan the document in order to access
this label later.
If you want to change the way certain labels are created, check out the
variable reftex-insert-label-flags (see Options (Creating Labels)).
If you are using AUCTeX to write your LaTeX documents, you can set it up to delegate the creation of labels to RefTeX. See AUCTeX, for more information.
RefTeX scans the document in order to find all labels. To make
referencing labels easier, it assigns to each label a category, the
label type (for example section, table, figure, equation, etc.).
In order to determine the label type, RefTeX parses around each label
to see in what kind of environments it is located. You can speed up
the parsing by using type-specific prefixes for labels and configuring
the variable reftex-trust-label-prefix.
Referencing Labels is really at the heart of RefTeX. Press C-c ) in order to reference a label (reftex-reference). This will start a selection process and finally insert the complete `\ref{label}' into the buffer.
First, RefTeX will determine the label category which is required. Often that can be figured out from context. For example, if you write `As shown in eq.' and the press C-c ), RefTeX knows that an equation label is going to be referenced. If it cannot figure out what label category is needed, it will query for one.
You will then be presented with a label selection menu. This is a special buffer which contains an outline of the document along with all labels of the given label category. In addition, next to the label there will be one line of context of the label definition, which is some text in the buffer near the label definition. Usually this is sufficient to identify the label. If you are unsure about a certain label, pressing <SPC> will show the label definition point in another window.
In order to reference a label, move to cursor to the correct label and
press <RET>. You can also reference several labels with a single
call to reftex-reference by marking entries with the m
key (see below).
Here is a list of special commands in the selection buffer. A summary of this information is always available from the selection process by pressing ?.
reftex-revisit-to-follow.
reftex-reference.
reftex-highlight-selection, Options (Misc).
\ref macros. The special markers `,-+' also store a
separator to be inserted before the corresponding reference. So marking
six entries with the keys `m , , - , +' will give a reference list
like this (see the variable reftex-multiref-punctuation)
In eqs. (1), (2), (3)--(4), (5) and (6)
\ref macro. Some packages like
saferef.sty support multiple references in this way.
\ref and \vref macro for references. The
\vref macro is defined in the varioref LaTeX package.
With this key you can force RefTeX to insert a \vref
macro. The current state of this flag is displayed by the `S<>'
indicator in the mode line of the selection buffer.
\ref, \fref and \Fref. The
\fref and \Fref macros are defined in the fancyref
LaTeX package. With this key you can force RefTeX to insert a
\fref or \Fref macro. The current state of this flag is
displayed by the `S<>' indicator in the mode line of the
selection buffer.
reftex-label-menu-flags (see Options (Referencing Labels)).
reftex-enable-partial-scans is
non-nil and your document is a multifile document, this will
reparse only a part of the document (the file in which the label at
point was defined).
xr it is possible to reference labels defined in another
document. This key will switch to the label menu of an external
document and let you select a label from there (see xr).
In order to define additional commands for the selection process, the
keymap reftex-select-label-map may be used.
RefTeX needs to be aware of the environments which can be referenced with a label (i.e. which carry their own counters). By default, RefTeX recognizes all labeled environments and macros discussed in The LaTeX Companion by Goossens, Mittelbach & Samarin, Addison-Wesley 1994.. These are:
figure, figure*, table, table*, equation,
eqnarray, enumerate, the \footnote macro (this is
the LaTeX core stuff)
align, gather, multline, flalign,
alignat, xalignat, xxalignat, subequations
(from AMS-LaTeX's amsmath.sty package)
\endnote macro (from endnotes.sty)
Beqnarray (fancybox.sty)
floatingfig (floatfig.sty)
longtable (longtable.sty)
figwindow, tabwindow (picinpar.sty)
SCfigure, SCtable (sidecap.sty)
sidewaysfigure, sidewaystable (rotating.sty)
subfigure, subfigure*, the \subfigure macro
(subfigure.sty)
supertabular (supertab.sty)
wrapfigure (wrapfig.sty)
If you want to use other labeled environments, defined with
\newtheorem, RefTeX needs to be configured to recognize
them (see Defining Label Environments).
RefTeX can be configured to recognize additional labeled
environments and macros. This is done with the variable
reftex-label-alist (see Options (Defining Label Environments)). If you are not familiar with Lisp, you can use the
custom library to configure this rather complex variable. To do
this, use
M-x customize-variable <RET> reftex-label-alist <RET>
Here we will discuss a few examples, in order to make things clearer.
It can also be instructive to look at the constant
reftex-label-alist-builtin which contains the entries for
all the builtin environments and macros (see Builtin Label Environments).
Suppose you are using \newtheorem in LaTeX in order to define two
new environments, theorem and axiom
\newtheorem{axiom}{Axiom}
\newtheorem{theorem}{Theorem}
to be used like this:
\begin{axiom}
\label{ax:first}
....
\end{axiom}
So we need to tell RefTeX that theorem and axiom are new
labeled environments which define their own label categories. We can
either use Lisp to do this (e.g. in .emacs) or use the custom
library. With Lisp it would look like this
(setq reftex-label-alist
'(("axiom" ?a "ax:" "~\\ref{%s}" nil ("axiom" "ax.") -2)
("theorem" ?h "thr:" "~\\ref{%s}" t ("theorem" "th.") -3)))
The type indicator characters ?a and ?h are used for
prompts when RefTeX queries for a label type. ?h
was chosen for theorem since ?t is already taken by
table. Note that also ?s, ?f, ?e,
?i, ?n are already used for standard environments.
The labels for Axioms and Theorems will have the prefixes `ax:' and `thr:', respectively. See AUCTeX, for information on how AUCTeX can use RefTeX to automatically create labels when a new environment is inserted into a buffer. Additionally, the following needs to be added to one's .emacs file before AUCTeX will automatically create labels for the new environments.
(add-hook 'LaTeX-mode-hook
(lambda ()
(LaTeX-add-environments
'("axiom" LaTeX-env-label)
'("theorem" LaTeX-env-label))))
The `~\ref{%s}' is a format string indicating how to insert references to these labels.
The next item indicates how to grab context of the label definition.
t means to get it from a default location (from the beginning of
a \macro or after the \begin statement). t is
not a good choice for eqnarray and similar environments.
nil means to use the text right after the label definition.
reftex-label-alist (Options (Defining Label Environments)).
The following list of strings is used to guess the correct label type from the word before point when creating a reference. E.g. if you write: `As we have shown in Theorem' and then press C-c ), RefTeX will know that you are looking for a theorem label and restrict the menu to only these labels without even asking.
The final item in each entry is the level at which the environment
should produce entries in the table of context buffer. If the number is
positive, the environment will produce numbered entries (like
\section), if it is negative the entries will be unnumbered (like
\section*). Use this only for environments which structure the
document similar to sectioning commands. For everything else, omit the
item.
To do the same configuration with customize, you need to click on
the [INS] button twice to create two templates and fill them in
like this:
Reftex Label Alist: [Hide]
[INS] [DEL] Package or Detailed : [Value Menu] Detailed:
Environment or \macro : [Value Menu] String: axiom
Type specification : [Value Menu] Char : a
Label prefix string : [Value Menu] String: ax:
Label reference format: [Value Menu] String: ~\ref{%s}
Context method : [Value Menu] After label
Magic words:
[INS] [DEL] String: axiom
[INS] [DEL] String: ax.
[INS]
[X] Make TOC entry : [Value Menu] Level: -2
[INS] [DEL] Package or Detailed : [Value Menu] Detailed:

Label prefix string : [Value Menu] String: thr:
Label reference format: [Value Menu] String: ~\ref{%s}

Magic words:
[INS] [DEL] String: theorem
[INS] [DEL] String: theor.
[INS] [DEL] String: th.
[INS]
[X] Make TOC entry : [Value Menu] Level: -3
Depending on how you would like the label insertion and selection for
the new environments to work, you might want to add the letters `a'
and `h' to some of the flags in the variables
reftex-insert-label-flags (see Options (Creating Labels))
and reftex-label-menu-flags (see Options (Referencing Labels)).
Suppose you would like to have a macro for quick equations. It could be defined like this:
\newcommand{\quickeq}[1]{\begin{equation} #1 \end{equation}}
and used like this:
Einstein's equation is \quickeq{E=mc^2 \label{eq:einstein}}.
We need to tell RefTeX that any label defined in the argument of the
\quickeq is an equation label. Here is how to do this with lisp:
(setq reftex-label-alist '(("\\quickeq{}" ?e nil nil 1 nil)))
The first element in this list is now the macro with empty braces as an
image of the macro arguments. ?e indicates that this is
an equation label, the different nil elements indicate to use the
default values for equations. The `1' as the fifth element
indicates that the context of the label definition should be the 1st
argument of the macro.
Here is again how this would look in the customization buffer:
Reftex Label Alist: [Hide]
[INS] [DEL] Package or Detailed : [Value Menu] Detailed:
Environment or \macro : [Value Menu] String: \quickeq{}
Type specification : [Value Menu] Char : e
Label prefix string : [Value Menu] Default
Label reference format: [Value Menu] Default
Context method : [Value Menu] Macro arg nr: 1
Magic words:
[INS]
[ ] Make TOC entry : [Value Menu] No entry
Suppose you want to make figures not directly with the figure environment, but with a macro like
\newcommand{\myfig}[5][tbp]{%
\begin{figure}[#1]
\epsimp[#5]{#2}
\caption{#3}
\label{#4}
\end{figure}}
which would be called like
\myfig[htp]{filename}{caption text}{label}{1}
Now we need to tell RefTeX that the 4th argument of the
\myfig macro is itself a figure label, and where to find
the context.
(setq reftex-label-alist
'(("\\myfig[]{}{}{*}{}" ?f nil nil 3)))
The empty pairs of brackets indicate the different arguments of the
\myfig macro. The `*' marks the label argument. ?f
indicates that this is a figure label which will be listed together with
labels from normal figure environments. The nil entries for
prefix and reference format mean to use the defaults for figure labels.
The `3' for the context method means to grab the 3rd macro argument
- the caption.
As a side effect of this configuration, reftex-label will now
insert the required naked label (without the \label macro) when
point is directly after the opening parenthesis of a \myfig macro
argument.
Again, here the configuration in the customization buffer:
[INS] [DEL] Package or Detailed : [Value Menu] Detailed:
Environment or \macro : [Value Menu] String: \myfig[]{}{}{*}{}
Type specification : [Value Menu] Char : f
Label prefix string : [Value Menu] Default
Label reference format: [Value Menu] Default
Context method : [Value Menu] Macro arg nr: 3
Magic words:
[INS]
[ ] Make TOC entry : [Value Menu] No entry
Sometimes you don't want to define a new label environment or macro, but
just change the information associated with a label category. Maybe you
want to add some magic words, for another language. Changing only the
information associated with a label category is done by giving
nil for the environment name and then specify the items you want
to define. Here is an example which adds German magic words to all
predefined label categories.
(setq reftex-label-alist
'((nil ?s nil nil nil ("Kapitel" "Kap." "Abschnitt" "Teil"))
(nil ?e nil nil nil ("Gleichung" "Gl."))
(nil ?t nil nil nil ("Tabelle"))
(nil ?f nil nil nil ("Figur" "Abbildung" "Abb."))
(nil ?n nil nil nil ("Anmerkung" "Anm."))
(nil ?i nil nil nil ("Punkt"))))
\eqref
Another case where one only wants to change the information associated
with the label category is to change the macro which is used for
referencing the label. When working with the AMS-LaTeX stuff, you might
prefer \eqref for doing equation references. Here is how to
do this:
(setq reftex-label-alist '((nil ?e nil "~\\eqref{%s}" nil nil)))
RefTeX has also a predefined symbol for this special purpose. The following is equivalent to the line above.
(setq reftex-label-alist '(AMSTeX))
Note that this is automatically done by the amsmath.el style file of AUCTeX (see Style Files) - so if you use AUCTeX, this configuration will not be necessary.
Some LaTeX packages define environment-like structures without using the
standard `\begin..\end' structure. RefTeX cannot parse
these directly, but you can write your own special-purpose parser and
use it instead of the name of an environment in an entry for
reftex-label-alist. The function should check if point is
currently in the special environment it was written to detect. If so,
it must return a buffer position indicating the start of this
environment. The return value must be nil on failure to detect
the environment. The function is called with one argument bound.
If non-nil, bound is a boundary for backwards searches
which should be observed. We will discuss two examples.
Some people define abbreviations for
environments, like \be for \begin{equation}, and
\ee for \end{equation}. The parser function would have
to search backward for these macros. When the first match is
\ee, point is not in this environment. When the first match is
\be, point is in this environment and the function must return
the beginning of the match. To avoid scanning too far, we can also look
for empty lines which cannot occur inside an equation environment.
Here is the setup:
;; Setup entry in reftex-label-alist, using all defaults for equations
(setq reftex-label-alist '((detect-be-ee ?e nil nil nil nil)))
(defun detect-be-ee (bound)
;; Search backward for the macros or an empty line
(if (re-search-backward
"\\(^[ \t]*\n\\|\\\\ee\\>\\)\\|\\(\\\\be\\>\\)" bound t)
(if (match-beginning 2)
(match-beginning 2) ; Return start of environment
nil) ; Return nil because env is closed
nil)) ; Return nil for not found
A more complex example is the linguex.sty package which defines list macros `\ex.', `\a.', `\b.' etc. for lists which are terminated by `\z.' or by an empty line.
\ex. \label{ex:12} Some text in an exotic language ...
\a. \label{ex:13} more stuff
\b. \label{ex:14} still more stuff
\a. List on a deeper level
\b. Another item
\b. and the third one
\z.
\b. Third item on this level.
... text after the empty line terminating all lists
The difficulty is that the `\a.' lists can nest and that an empty line terminates all list levels in one go. So we have to count nesting levels between `\a.' and `\z.'. Here is the implementation for RefTeX.
(setq reftex-label-alist
'((detect-linguex ?x "ex:" "~\\ref{%s}" nil ("Example" "Ex."))))
(defun detect-linguex (bound)
(let ((cnt 0))
(catch 'exit
(while
;; Search backward for all possible delimiters
(re-search-backward
(concat "\\(^[ \t]*\n\\)\\|\\(\\\\z\\.\\)\\|"
"\\(\\ex[ig]?\\.\\)\\|\\(\\\\a\\.\\)")
nil t)
;; Check which delimiter was matched.
(cond
((match-beginning 1)
;; empty line terminates all - return nil
(throw 'exit nil))
((match-beginning 2)
;; \z. terminates one list level - decrease nesting count
(decf cnt))
((match-beginning 3)
;; \ex. : return match unless there was a \z. on this level
(throw 'exit (if (>= cnt 0) (match-beginning 3) nil)))
((match-beginning 4)
;; \a. : return match when on level 0, otherwise
;; increment nesting count
(if (>= cnt 0)
(throw 'exit (match-beginning 4))
(incf cnt))))))))
When you have to put several entries into reftex-label-alist, just
put them after each other in a list, or create that many templates in
the customization buffer. Here is a lisp example which uses several of
the entries described above:
(setq reftex-label-alist
'(("axiom" ?a "ax:" "~\\ref{%s}" nil ("axiom" "ax.") -2)
("theorem" ?h "thr:" "~\\ref{%s}" t ("theorem" "theor." "th.") -3)
("\\quickeq{}" ?e nil nil 1 nil)
AMSTeX
("\\myfig[]{}{}{*}{}" ?f nil nil 3)
(detect-linguex ?x "ex:" "~\\ref{%s}" nil ("Example" "Ex."))))
When point is idle for more than reftex-idle-time seconds on the
argument of a \ref macro, the echo area will display some
information about the label referenced there. Note that the information
is only displayed if the echo area is not occupied by a different
message.
RefTeX can also display the label definition corresponding to a
\ref macro, or all reference locations corresponding to a
\label macro. See Viewing Cross-References, for more
information.
xr: Cross-Document References
The LaTeX package xr makes it possible to create references to
labels defined in external documents. The preamble of a document using
xr will contain something like this:
\usepackage{xr}
\externaldocument[V1-]{volume1}
\externaldocument[V3-]{volume3}
and we can make references to any labels defined in these external documents by using the prefixes `V1-' and `V3-', respectively.
RefTeX can be used to create such references as well. Start the referencing process normally, by pressing C-c ). Select a label type if necessary. When you see the label selection buffer, pressing x will switch to the label selection buffer of one of the external documents. You may then select a label as before and RefTeX will insert it along with the required prefix.
For this kind of inter-document cross-references, saving of parsing information and the use of multiple selection buffers can mean a large speed-up (see Optimizations).
varioref: Variable Page Referencesvarioref is a frequently used LaTeX package to create
cross–references with page information. When you want to make a
reference with the \vref macro, just press the v key in the
selection buffer to toggle between \ref and \vref
(see Referencing Labels). The mode line of the selection buffer
shows the current status of this switch. If you find that you almost
always use \vref, you may want to make it the default by
customizing the variable reftex-vref-is-default. If this
toggling seems too inconvenient, you can also use the command
reftex-varioref-vref2.
Or use AUCTeX to create your macros (see AUCTeX).
fancyref: Fancy Cross Referencesfancyref is a LaTeX package where a macro call like
\fref{fig:map-of-germany} creates not only the number of
the referenced counter but also the complete text around it, like
`Figure 3 on the preceding page'. In order to make it work you
need to use label prefixes like `fig:' consistently - something
RefTeX does automatically. When you want to make a reference
with the \fref macro, just press the V key in the selection
buffer to cycle between \ref, \fref and \Fref
(see Referencing Labels). The mode line of the selection buffer
shows the current status of this switch. If this cycling seems
inconvenient, you can also use the commands reftex-fancyref-fref
and reftex-fancyref-Fref3. Or use AUCTeX to create your macros
(see AUCTeX).
Citations in LaTeX are done with the \cite macro or variations of
it. The argument of the macro is a citation key which identifies an
article or book in either a BibTeX database file or in an explicit
thebibliography environment in the document. RefTeX's
support for citations helps to select the correct key quickly.
In order to create a citation, press C-c [. RefTeX then prompts for a regular expression which will be used to search through the database and present the list of matches to choose from in a selection process similar to that for selecting labels (see Referencing Labels).
The regular expression uses an extended syntax: `&&' defines a
logic and for regular expressions. For example
`Einstein&&Bose' will match all articles which mention
Bose-Einstein condensation, or which are co-authored by Bose and
Einstein. When entering the regular expression, you can complete on
known citation keys. RefTeX also offers a default when prompting for a
regular expression. This default is the word before the cursor or the
word before the current `\cite' command. Sometimes this may be a
good search key.
RefTeX prefers to use BibTeX database files specified with a
\bibliography macro to collect its information. Just like
BibTeX, it will search for the specified files in the current directory
and along the path given in the environment variable BIBINPUTS.
If you do not use BibTeX, but the document contains an explicit
thebibliography environment, RefTeX will collect its
information from there. Note that in this case the information
presented in the selection buffer will just be a copy of relevant
\bibitem entries, not the structured listing available with
BibTeX database files.
In the selection buffer, the following keys provide special commands. A summary of this information is always available from the selection process by pressing ?.
reftex-highlight-selection, Options (Misc).
\cite macro referring to them.
\cite macro for each of it.
reftex-citation.
In order to define additional commands for this selection process, the
keymap reftex-select-bib-map may be used.
The standard LaTeX macro \cite works well with numeric or simple
key citations. To deal with the more complex task of author-year
citations as used in many natural sciences, a variety of packages has
been developed which define derived forms of the \cite macro.
RefTeX can be configured to produce these citation macros as well
by setting the variable reftex-cite-format. For the most
commonly used packages (natbib, harvard, chicago,
jurabib) this may be done from the menu, under
Ref->Citation Styles. Since there are usually several macros to
create the citations, executing reftex-citation (C-c [)
starts by prompting for the correct macro. For the Natbib style, this
looks like this:
SELECT A CITATION FORMAT
[^M] \cite{%l}
[t] \citet{%l}
[T] \citet*{%l}
[p] \citep{%l}
[P] \citep*{%l}
[e] \citep[e.g.][]{%l}
[s] \citep[see][]{%l}
[a] \citeauthor{%l}
[A] \citeauthor*{%l}
[y] \citeyear{%l}
If cite formats contain empty paris of square brackets, RefTeX can
will prompt for values of these optional arguments if you call the
reftex-citation command with a C-u prefix.
Following the most generic of these packages, natbib, the builtin
citation packages always accept the t key for a textual
citation (like: Jones et al. (1997) have shown...) as well as
the p key for a parenthetical citation (like: As shown
earlier (Jones et al, 1997)).
To make one of these styles the default, customize the variable
reftex-cite-format or put into .emacs:
(setq reftex-cite-format 'natbib)
You can also use AUCTeX style files to automatically set the
citation style based on the usepackage commands in a given
document. See Style Files, for information on how to set up the style
files correctly.
Top
When point is idle for more than reftex-idle-time seconds on the
argument of a \cite macro, the echo area will display some
information about the article cited there. Note that the information is
only displayed if the echo area is not occupied by a different message.
RefTeX can also display the \bibitem or BibTeX database
entry corresponding to a \cite macro, or all citation locations
corresponding to a \bibitem or BibTeX database entry.
See Viewing Cross-References.
chapterbib and bibunits are two LaTeX packages which
produce multiple bibliographies in a document. This is no problem for
RefTeX as long as all bibliographies use the same BibTeX database
files. If they do not, it is best to have each document part in a
separate file (as it is required for chapterbib anyway). Then
RefTeX will still scan the locally relevant databases correctly. If
you have multiple bibliographies within a single file, this may
or may not be the case.
The command reftex-citation can also be executed outside a LaTeX
buffer. This can be useful to reference articles in the mail buffer and
other documents. You should not enter reftex-mode for
this, just execute the command. The list of BibTeX files will in this
case be taken from the variable reftex-default-bibliography.
Setting the variable reftex-cite-format to the symbol
locally does a decent job of putting all relevant information
about a citation directly into the buffer. Here is the lisp code to add
the C-c [ binding to the mail buffer. It also provides a local
binding for reftex-cite-format.
(add-hook 'mail-setup-hook
(lambda () (define-key mail-mode-map "\C-c["
(lambda ()
(interactive)
(let ((reftex-cite-format 'locally))
(reftex-citation))))))
RefTeX offers two ways to create a new BibTeX database file.
The first option produces a file which contains only the entries
actually referenced in the current document. This can be useful if
the database in only meant for a single document and you want to clean
it of old and unused ballast. It can also be useful while writing a
document together with collaborators, in order to avoid sending around
the entire (possibly very large) database. To create the file, use
M-x reftex-create-bibtex-file, also available from the menu
under Ref->Global Actions->Create Bibtex File. The command will
prompt for a BibTeX file name and write the extracted entries to that
file.
The second option makes use of the selection process started by the command C-c [ (see Creating Citations). This command uses a regular expression to select entries, and lists them in a formatted selection buffer. After pressing the e key (mnemonics: Export), the command will prompt for the name of a new BibTeX file and write the selected entries to that file. You can also first mark some entries in the selection buffer with the m key and then export either the marked entries (with the e key) or the unmarked entries (with the E key).
LaTeX has builtin support for creating an Index. The LaTeX core supports two different indices, the standard index and a glossary. With the help of special LaTeX packages (multind.sty or index.sty), any number of indices can be supported.
Index entries are created with the \index{entry} macro.
All entries defined in a document are written out to the .aux
file. A separate tool must be used to convert this information into a
nicely formatted index. Tools used with LaTeX include MakeIndex
and xindy.
Indexing is a very difficult task. It must follow strict conventions to make the index consistent and complete. There are basically two approaches one can follow, and both have their merits.
Before you start, you need to make sure that RefTeX knows about
the index style being used in the current document. RefTeX has
builtin support for the default \index and \glossary
macros. Other LaTeX packages, like the multind or index
package, redefine the \index macro to have an additional
argument, and RefTeX needs to be configured for those. A
sufficiently new version of AUCTeX (9.10c or later) will do this
automatically. If you really don't use AUCTeX (you should!), this
configuration needs to be done by hand with the menu (Ref->Index
Style), or globally for all your documents with
(setq reftex-index-macros '(multind)) or
(setq reftex-index-macros '(index))
In order to index the current selection or the word at the cursor press
C-c / (reftex-index-selection-or-word). This causes the
selection or word `word' to be replaced with
`\index{word}word'. The macro which is used
(\index by default) can be configured with the variable
reftex-index-default-macro. When the command is called with a
prefix argument (C-u C-c /), you get a chance to edit the
generated index entry. Use this to change the case of the word or to
make the entry a subentry, for example by entering
`main!sub!word'. When called with two raw C-u prefixes
(C-u C-u C-c /), you will be asked for the index macro as well.
When there is nothing selected and no word at point, this command will
just call reftex-index, described below.
In order to create a general index entry, press C-c <
(reftex-index). RefTeX will prompt for one of the
available index macros and for its arguments. Completion will be
available for the index entry and, if applicable, the index tag. The
index tag is a string identifying one of multiple indices. With the
multind and index packages, this tag is the first argument
to the redefined \index macro.
RefTeX maintains a file in which phrases can be collected for
later indexing. The file is located in the same directory as the master
file of the document and has the extension .rip (Reftex
Index Phrases). You can create or visit the file with C-c
| (reftex-index-visit-phrases-buffer). If the file is empty it
is initialized by inserting a file header which contains the definition
of the available index macros. This list is initialized from
reftex-index-macros (see Defining Index Macros). You can
edit the header as needed, but if you define new LaTeX indexing macros,
don't forget to add them to reftex-index-macros as well. Here is
a phrase file header example:
% -*- mode: reftex-index-phrases -*-
% Key Macro Format Repeat
%----------------------------------------------------------
>>>INDEX_MACRO_DEFINITION: i \index{%s} t
>>>INDEX_MACRO_DEFINITION: I \index*{%s} nil
>>>INDEX_MACRO_DEFINITION: g \glossary{%s} t
>>>INDEX_MACRO_DEFINITION: n \index*[name]{%s} nil
%----------------------------------------------------------
The macro definition lines consist of a unique letter identifying a
macro, a format string and the repeat flag, all separated by
<TAB>. The format string shows how the macro is to be applied, the
`%s' will be replaced with the index entry. The repeat flag
indicates if word is indexed by the macro as
`\index{word}' (repeat = nil) or as
`\index{word}word' (repeat = t). In the
above example it is assumed that the macro \index*{word}
already typesets its argument in the text, so that it is unnecessary to
repeat word outside the macro.
Phrases for indexing can be collected while writing the document. The
command C-c \ (reftex-index-phrase-selection-or-word)
copies the current selection (if active) or the word near point into the
phrases buffer. It then selects this buffer, so that the phrase line
can be edited. To return to the LaTeX document, press C-c C-c
(reftex-index-phrases-save-and-return).
You can also prepare the list of index phrases in a different way and copy it into the phrases file. For example you might want to start from a word list of the document and remove all words which should not be indexed.
The phrase lines in the phrase buffer must have a specific format. RefTeX will use font-lock to indicate if a line has the proper format. A phrase line looks like this:
[key] <TABs> phrase [<TABs> arg[&&arg]... [ || arg]...]
<TABs> stands for white space containing at least one <TAB>.
key must be at the start of the line and is the character
identifying one of the macros defined in the file header. It is
optional - when omitted, the first macro definition line in the file
will be used for this phrase. The phrase is the phrase to be
searched for when indexing. It may contain several words separated by
spaces. By default the search phrase is also the text entered as
argument of the index macro. If you want the index entry to be
different from the search phrase, enter another <TAB> and the index
argument arg. If you want to have each match produce several
index entries, separate the different index arguments with ` &&
'4. If you want to be
able to choose at each match between several different index arguments,
separate them with ` || '5. Here is an
example:
%--------------------------------------------------------------------
I Sun
i Planet Planets
i Vega Stars!Vega
Jupiter Planets!Jupiter
i Mars Planets!Mars || Gods!Mars || Chocolate Bars!Mars
i Pluto Planets!Pluto && Kuiper Belt Objects!Pluto
So `Sun' will be indexed directly as `\index*{Sun}', while `Planet' will be indexed as `\index{Planets}Planet'. `Vega' will be indexed as a subitem of `Stars'. The `Jupiter' line will also use the `i' macro as it was the first macro definition in the file header (see above example). At each occurrence of `Mars' you will be able choose between indexing it as a subitem of `Planets', `Gods' or `Chocolate Bars'. Finally, every occurrence of `Pluto' will be indexed as `\index{Planets!Pluto}\index{Kuiper Belt Objects!Pluto}Pluto' and will therefore create two different index entries.
Before indexing the phrases in the phrases buffer, they should be
checked carefully for consistency. A first step is to sort the phrases
alphabetically - this is done with the command C-c C-s
(reftex-index-sort-phrases). It will sort all phrases in the
buffer alphabetically by search phrase. If you want to group certain
phrases and only sort within the groups, insert empty lines between the
groups. Sorting will only change the sequence of phrases within each
group (see the variable reftex-index-phrases-sort-in-blocks).
A useful command is C-c C-i (reftex-index-phrases-info)
which lists information about the phrase at point, including an example
of how the index entry will look like and the number of expected matches
in the document.
Another important check is to find out if there are double or
overlapping entries in the buffer. For example if you are first
searching and indexing `Mars' and then `Planet Mars', the
second phrase will not match because of the index macro inserted before
`Mars' earlier. The command C-c C-t
(reftex-index-find-next-conflict-phrase) finds the next phrase in
the buffer which is either duplicate or a subphrase of another phrase.
In order to check the whole buffer like this, start at the beginning and
execute this command repeatedly.
Once the index phrases have been collected and organized, you are set for global indexing. I recommend to do this only on an otherwise finished document. Global indexing starts from the phrases buffer. There are several commands which start indexing: C-c C-x acts on the current phrase line, C-c C-r on all lines in the current region and C-c C-a on all phrase lines in the buffer. It is probably good to do indexing in small chunks since your concentration may not last long enough to do everything in one go.
RefTeX will start at the first phrase line and search the phrase globally in the whole document. At each match it will stop, compute the replacement string and offer you the following choices6:
The `Find and Index in Document' menu in the phrases buffer also lists a few options for the indexing process. The options have associated customization variables to set the defaults (see Options (Index Support)). Here is a short explanation of what the options do:
reftex-index-macros. Intended for
re-indexing a documents after changes have been made.
Even though indexing should be the last thing you do to a document, you
are bound to make changes afterwards. Indexing then has to be applied
to the changed regions. The command
reftex-index-phrases-apply-to-region is designed for this
purpose. When called from a LaTeX document with active region, it will
apply reftex-index-all-phrases to the current region.
In order to compile and display the index, press C-c >. If the document uses multiple indices, RefTeX will ask you to select one. Then, all index entries will be sorted alphabetically and displayed in a special buffer, the *Index* buffer. From that buffer you can check and edit each entry.
The index can be restricted to the current section or the region. Then only entries in that part of the document will go into the compiled index. To restrict to the current section, use a numeric prefix `2', thus press C-u 2 C-c >. To restrict to the current region, make the region active and use a numeric prefix `3' (press C-u 3 C-c >). From within the *Index* buffer the restriction can be moved from one section to the next by pressing the < and > keys.
One caveat: RefTeX finds the definition point of an index entry by searching near the buffer position where it had found to macro during scanning. If you have several identical index entries in the same buffer and significant changes have shifted the entries around, you must rescan the buffer to ensure the correspondence between the *Index* buffer and the definition locations. It is therefore advisable to rescan the document (with r or C-u r) frequently while editing the index from the *Index* buffer.
Here is a list of special commands available in the *Index* buffer. A summary of this information is always available by pressing ?.
reftex-index-follow-mode. Note that only context in files
already visited is shown. RefTeX will not visit a file just for
follow mode. See, however, the variable
reftex-revisit-to-follow.
undo function for this.
MakeIndex, this part is an encapsulating
macro. With xindy, it is called attribute and is a
property of the index entry that can lead to special formatting. When
called with C-u prefix, kill the entire attribute
part.
MakeIndex to change the visual
appearance of the entry in the index. When called with C-u
prefix, kill the entire visual part.
reftex-index-include-context.
R<> indicator in the
mode line and in the header of the *Index* buffer.
reftex-enable-partial-scans is non-nil, rescan only the file this
location is defined in, not the entire document.
RefTeX by default recognizes the \index and
\glossary macros which are defined in the LaTeX core. It has
also builtin support for the re-implementations of \index
in the multind and index packages. However, since
the different definitions of the \index macro are incompatible,
you will have to explicitly specify the index style used.
See Creating Index Entries, for information on how to do that.
When writing a document with an index you will probably define additional macros which make entries into the index. Let's look at an example.
\newcommand{\ix}[1]{#1\index{#1}}
\newcommand{\nindex}[1]{\textit{#1}\index[name]{#1}}
\newcommand{\astobj}[1]{\index{Astronomical Objects!#1}}
The first macro \ix typesets its argument in the text and places
it into the index. The second macro \nindex typesets its
argument in the text and places it into a separate index with the tag
`name'7. The last macro also places its argument into the index, but as
subitems under the main index entry `Astronomical Objects'. Here
is how to make RefTeX recognize and correctly interpret these
macros, first with Emacs Lisp.
(setq reftex-index-macros
'(("\\ix{*}" "idx" ?x "" nil nil)
("\\nindex{*}" "name" ?n "" nil nil)
("\\astobj{*}" "idx" ?o "Astronomical Objects!" nil t)))
Note that the index tag is `idx' for the main index, and `name' for the name index. `idx' and `glo' are reserved for the default index and for the glossary.
The character arguments ?x, ?n, and ?o are for
quick identification of these macros when RefTeX inserts new
index entries with reftex-index. These codes need to be
unique. ?i, ?I, and ?g are reserved for the
\index, \index*, and \glossary macros,
respectively.
The following string is empty unless your macro adds a superordinate
entry to the index key - this is the case for the \astobj macro.
The next entry can be a hook function to exclude certain matches, it
almost always can be nil.
The final element in the list indicates if the text being indexed needs
to be repeated outside the macro. For the normal index macros, this
should be t. Only if the macro typesets the entry in the text
(like \ix and \nindex in the example do), this should be
nil.
To do the same thing with customize, you need to fill in the templates like this:
Repeat:
[INS] [DEL] List:
Macro with args: \ix{*}
Index Tag : [Value Menu] String: idx
Access Key : x
Key Prefix :
Exclusion hook : nil
Repeat Outside : [Toggle] off (nil)
[INS] [DEL] List:
Macro with args: \nindex{*}
Index Tag : [Value Menu] String: name
Access Key : n
Key Prefix :
Exclusion hook : nil
Repeat Outside : [Toggle] off (nil)
[INS] [DEL] List:
Macro with args: \astobj{*}
Index Tag : [Value Menu] String: idx
Access Key : o
Key Prefix : Astronomical Objects!
Exclusion hook : nil
Repeat Outside : [Toggle] on (non-nil)
[INS]
With the macro \ix defined, you may want to change the default
macro used for indexing a text phrase (see Creating Index Entries).
This would be done like this
(setq reftex-index-default-macro '(?x "idx"))
which specifies that the macro identified with the character ?x (the
\ix macro) should be used for indexing phrases and words already
in the buffer with C-c / (reftex-index-selection-or-word).
The index tag is "idx".
RefTeX can display cross–referencing information. This means,
if two document locations are linked, RefTeX can display the
matching location(s) in another window. The \label and \ref
macros are one way of establishing such a link. Also, a \cite
macro is linked to the corresponding \bibitem macro or a BibTeX
database entry.
The feature is invoked by pressing C-c &
(reftex-view-crossref) while point is on the key argument
of a macro involved in cross–referencing. You can also click with
S-mouse-2 on the macro argument. Here is what will happen for
individual classes of macros:
\ref\ref macro are active for
cross–reference display. This works also for labels defined in an
external document when the current document refers to them through the
xr interface (see xr (LaTeX package)).
\label\label macro but also other macros
with label arguments (as configured with reftex-label-alist) are
active for cross–reference display.
\cite\bibitem.
All usual variants9 of the \cite macro are active for cross–reference
display.
\bibitem\index\index
and \glossary macros, all macros configured in
reftex-index-macros will be recognized.
While the display of cross referencing information for the above
mentioned macros is hard–coded, you can configure additional relations
in the variable reftex-view-crossref-extra.
RefTeX installs a Ref menu in the menu bar on systems
which support this. From this menu you can access all of
RefTeX's commands and a few of its options. There is also a
Customize submenu which can be used to access RefTeX's
entire set of options.
Here is a summary of the available key bindings.
C-c =reftex-tocC-c -reftex-toc-recenterC-c (reftex-labelC-c )reftex-referenceC-c [reftex-citationC-c &reftex-view-crossrefS-mouse-2reftex-mouse-view-crossrefC-c /reftex-index-selection-or-wordC-c \reftex-index-phrase-selection-or-wordC-c |reftex-index-visit-phrases-bufferC-c <reftex-indexC-c >reftex-display-index
Note that the S-mouse-2 binding is only provided if this key is not already used by some other package. RefTeX will not override an existing binding to S-mouse-2.
Personally, I also bind some functions in the users C-c map for easier access.
C-c treftex-tocC-c lreftex-labelC-c rreftex-referenceC-c creftex-citationC-c vreftex-view-crossrefC-c sreftex-search-documentC-c greftex-grep-document
These keys are reserved for the user, so I cannot bind them by default. If you want to have these key bindings available, set in your .emacs file:
(setq reftex-extra-bindings t)
Changing and adding to RefTeX's key bindings is best done in the hook
reftex-load-hook. For information on the keymaps
which should be used to add keys, see Keymaps and Hooks.
RefTeX uses faces when available to structure the selection and
table of contents buffers. It does not create its own faces, but uses
the ones defined in font-lock.el. Therefore, RefTeX will
use faces only when font-lock is loaded. This seems to be
reasonable because people who like faces will very likely have it
loaded. If you wish to turn off fontification or change the involved
faces, see Options (Fontification).
The following is relevant when working with documents spread over many files:
grep, search and
query-replace on all files which are part of a multifile
document.
TeX-master for AUCTeX or tex-main-file for the
standard Emacs LaTeX mode) containing the name of the master file. For
example, to set the file variable TeX-master, include something
like the following at the end of each TeX file:
%%% Local Variables: ***
%%% mode:latex ***
%%% TeX-master: "thesis.tex" ***
%%% End: ***
AUCTeX with the setting
(setq-default TeX-master nil)
will actually ask you for each new file about the master file and insert this comment automatically. For more details see the documentation of the AUCTeX (see Multifile), the documentation about the Emacs (La)TeX mode (see TeX Print) and the Emacs documentation on File Variables (see File Variables).
Some parts of RefTeX are language dependent. The default settings work well for English. If you are writing in a different language, the following hints may be useful:
reftex-derive-label-parameters and reftex-abbrev-parameters.
reftex-translate-to-ascii-function and
reftex-label-illegal-re.
reftex-multiref-punctuation and
reftex-cite-punctuation.
In order to find files included in a document via \input or
\include, RefTeX searches all directories specified in the
environment variable TEXINPUTS. Similarly, it will search the
path specified in the variables BIBINPUTS and TEXBIB for
BibTeX database files.
When searching, RefTeX will also expand recursive path definitions (directories ending in `//' or `!!'). But it will only search and expand directories explicitly given in these variables. This may cause problems under the following circumstances:
There are three ways to solve this problem:
TEXINPUTS and BIBINPUTS, define your own
variables and configure RefTeX to use them instead:
(setq reftex-texpath-environment-variables '("MYTEXINPUTS"))
(setq reftex-bibpath-environment-variables '("MYBIBINPUTS"))
(setq reftex-texpath-environment-variables
'("./inp:/home/cd/tex//:/usr/local/tex//"))
(setq reftex-bibpath-environment-variables
'("/home/cd/tex/lit/"))
teTeX uses the
kpathsearch library which provides the command kpsewhich
to search for files. RefTeX can be configured to use this
program. Note that the exact syntax of the kpsewhich
command depends upon the version of that program.
(setq reftex-use-external-file-finders t)
(setq reftex-external-file-finders
'(("tex" . "kpsewhich -format=.tex %f")
("bib" . "kpsewhich -format=.bib %f")))
Some people like to use RefTeX with noweb files, which usually have the
extension .nw. In order to deal with such files, the new
extension must be added to the list of valid extensions in the variable
reftex-file-extensions. When working with AUCTeX as major mode,
the new extension must also be known to AUCTeX via the variable
TeX-file-extension. For example:
(setq reftex-file-extensions
'(("nw" "tex" ".tex" ".ltx") ("bib" ".bib")))
(setq TeX-file-extensions
'( "nw" "tex" "sty" "cls" "ltx" "texi" "texinfo"))
Note added 2002. Computers have gotten a lot faster, so most of the optimizations discussed below will not be necessary on new machines. I am leaving this stuff in the manual for people who want to write thick books, where some of it still might be useful.
Implementing the principle of least surprises, the default settings of RefTeX ensure a safe ride for beginners and casual users. However, when using RefTeX for a large project and/or on a small computer, there are ways to improve speed or memory usage.
(setq reftex-keep-temporary-buffers nil)
reftex-label
(C-u C-c (), reftex-reference (C-u C-c )),
reftex-citation (C-u C-c [), reftex-toc (C-u C-c
=), and reftex-view-crossref (C-u C-c &) initiates
re-parsing of the entire document in order to update the parsing
information. For a large document this can be unnecessary, in
particular if only one file has changed. RefTeX can be configured
to do partial scans instead of full ones. C-u re-parsing then
does apply only to the current buffer and files included from it.
Likewise, the r key in both the label selection buffer and the
table-of-contents buffer will only prompt scanning of the file in which
the label or section macro near the cursor was defined. Re-parsing of
the entire document is still available by using C-u C-u as a
prefix, or the capital R key in the menus. To use this feature,
try
(setq reftex-enable-partial-scans t)
reftex-mode or when you exit Emacs. The information is
restored when you begin working with a document in a new editing
session. To use this feature, put into .emacs:
(setq reftex-save-parse-info t)
(setq reftex-trust-label-prefix '("fn:" "eq:"))
(setq reftex-allow-automatic-rescan nil)
RefTeX will then occasionally annotate new labels in the selection buffer, saying that their position in the label list in uncertain. A manual document scan will fix this.
reftex-label. Updating the buffer takes as long as recreating it
- so the time saving is limited to cases where no new labels of that
category have been added. To turn on this feature, use
(setq reftex-use-multiple-selection-buffers t)
You can also inhibit the automatic updating entirely. Then the selection buffer will always pop up very fast, but may not contain the most recently defined labels. You can always update the buffer by hand, with the g key. To get this behavior, use instead
(setq reftex-use-multiple-selection-buffers t
reftex-auto-update-selection-buffers nil)
As a summary, here are the settings I recommend for heavy use of RefTeX with large documents:
(setq reftex-enable-partial-scans t
reftex-save-parse-info t
reftex-use-multiple-selection-buffers t)
AUCTeX is without doubt the best major mode for editing TeX and LaTeX files with Emacs (see AUCTeX). If AUCTeX is not part of your Emacs distribution, you can get it10 by ftp from the AUCTeX distribution site.
RefTeX contains code to interface with AUCTeX. When this interface is turned on, both packages will interact closely. Instead of using RefTeX's commands directly, you can then also use them indirectly as part of the AUCTeX environment11. The interface is turned on with
(setq reftex-plug-into-AUCTeX t)
If you need finer control about which parts of the interface are used
and which not, read the docstring of the variable
reftex-plug-into-AUCTeX or customize it with M-x
customize-variable <RET> reftex-plug-into-AUCTeX <RET>.
The following list describes the individual parts of the interface.
reftex-label to insert labelsreftex-label is called instead.
For example, if you type C-c C-e equation <RET>, AUCTeX and
RefTeX will insert
\begin{equation}
\label{eq:1}
\end{equation}
without further prompts.
Similarly, when you type C-c C-s section <RET>, RefTeX will offer its default label which is derived from the section title.
TeX-arg-label, TeX-arg-cite, and TeX-arg-index to
prompt for arguments which are labels, citation keys and index entries.
The interface takes over these functions12 and
supplies the macro arguments with RefTeX's mechanisms. For
example, when you type C-c <RET> ref <RET>, RefTeX
will supply its label selection process (see Referencing Labels).
Style files are Emacs Lisp files which are evaluated by AUCTeX in
association with the \documentclass and \usepackage
commands of a document (see Style Files). Support for
RefTeX in such a style file is useful when the LaTeX style
defines macros or environments connected with labels, citations, or the
index. Many style files (e.g. amsmath.el or natbib.el)
distributed with AUCTeX already support RefTeX in this
way.
Before calling a RefTeX function, the style hook should always test for the availability of the function, so that the style file will also work for people who do not use RefTeX.
Additions made with style files in the way described below remain local
to the current document. For example, if one package uses AMSTeX, the
style file will make RefTeX switch over to \eqref, but
this will not affect other documents.
A style hook may contain calls to
reftex-add-label-environments13 which defines additions to
reftex-label-alist. The argument taken by this function must have
the same format as reftex-label-alist. The amsmath.el
style file of AUCTeX for example contains the following:
(TeX-add-style-hook "amsmath"
(lambda ()
(if (fboundp 'reftex-add-label-environments)
(reftex-add-label-environments '(AMSTeX)))))
while a package myprop defining a proposition environment
with \newtheorem might use
(TeX-add-style-hook "myprop"
(lambda ()
(LaTeX-add-environments '("proposition" LaTeX-env-label))
(if (fboundp 'reftex-add-label-environments)
(reftex-add-label-environments
'(("proposition" ?p "prop:" "~\\ref{%s}" t
("Proposition" "Prop.") -3))))))
Similarly, a style hook may contain a call to
reftex-set-cite-format to set the citation format. The style
file natbib.el for the Natbib citation style does switch
RefTeX's citation format like this:
(TeX-add-style-hook "natbib"
(lambda ()
(if (fboundp 'reftex-set-cite-format)
(reftex-set-cite-format 'natbib))))
The hook may contain a call to reftex-add-index-macros to
define additional \index-like macros. The argument must have
the same format as reftex-index-macros. It may be a symbol, to
trigger support for one of the builtin index packages. For example,
the style multind.el contains
(TeX-add-style-hook "multind"
(lambda ()
(and (fboundp 'reftex-add-index-macros)
(reftex-add-index-macros '(multind)))))
If you have your own package myindex which defines the following macros to be used with the LaTeX index.sty file
\newcommand{\molec}[1]{#1\index{Molecules!#1}}
\newcommand{\aindex}[1]{#1\index[author]{#1}
you could write this in the style file myindex.el:
(TeX-add-style-hook "myindex"
(lambda ()
(TeX-add-symbols
'("molec" TeX-arg-index)
'("aindex" TeX-arg-index))
(if (fboundp 'reftex-add-index-macros)
(reftex-add-index-macros
'(("molec{*}" "idx" ?m "Molecules!" nil nil)
("aindex{*}" "author" ?a "" nil nil))))))
Finally the hook may contain a call to reftex-add-section-levels
to define additional section statements. For example, the FoilTeX class
has just two headers, \foilhead and \rotatefoilhead. Here
is a style file foils.el that will inform RefTeX about these:
(TeX-add-style-hook "foils"
(lambda ()
(if (fboundp 'reftex-add-section-levels)
(reftex-add-section-levels '(("foilhead" . 3)
("rotatefoilhead" . 3))))))
Once you have written a document with labels, references and citations,
it can be nice to read it like a hypertext document. RefTeX has
support for that: reftex-view-crossref (bound to C-c
&), reftex-mouse-view-crossref (bound to S-mouse-2), and
reftex-search-document. A somewhat fancier interface with mouse
highlighting is provided (among other things) by Peter S. Galbraith's
bib-cite.el. There is some overlap in the functionalities of
Bib-cite and RefTeX. Bib-cite.el comes bundled with
AUCTeX.
Bib-cite version 3.06 and later can be configured so that bib-cite's
mouse functions use RefTeX for displaying references and citations.
This can be useful in particular when working with the LaTeX xr
package or with an explicit thebibliography environment (rather
than BibTeX). Bib-cite cannot handle those, but RefTeX does. To
make use of this feature, try
(setq bib-cite-use-reftex-view-crossref t)
\input, \include, and \section (etc.) statements
have to be first on a line (except for white space).
reftex-enable-partial-scans), the section
numbers in the table of contents may eventually become wrong. A full
scan will fix this.
reftex-label-alist are
global and apply to all documents. If you need to make definitions
local to a document, because they would interfere with settings in other
documents, you should use AUCTeX and set up style files with calls to
reftex-add-label-environments, reftex-set-cite-format,
reftex-add-index-macros, and reftex-add-section-levels.
Settings made with these functions remain local to the current
document. See AUCTeX.
reftex-toc may have problems to jump to an affected
section heading. There are three possible ways to deal with
this:
(setq reftex-keep-temporary-buffers t)(setq reftex-initialize-temporary-buffers t)reftex-initialize-temporary-buffers to a list of hook
functions doing a minimal initialization.
reftex-refontify-context.
\begin macro
to specify a label. E.g. Lamport's pf.sty uses both
\step{label}{claim} and \begin{step+}{label}
claim
\end{step+}
We need to trick RefTeX into swallowing this:
;; Configuration for Lamport's pf.sty
(setq reftex-label-alist
'(("\\step{*}{}" ?p "st:" "~\\stepref{%s}" 2 ("Step" "St."))
("\\begin{step+}{*}" ?p "st:" "~\\stepref{%s}" 1000)))
The first line is just a normal configuration for a macro. For the
step+ environment we actually tell RefTeX to look for the
macro `\begin{step+}' and interpret the first
argument (which really is a second argument to the macro \begin)
as a label of type ?p. Argument count for this macro starts only
after the `{step+}', also when specifying how to get
context.
(setq reftex-use-itimer-in-xemacs t)

RefTeX is bundled and pre-installed with Emacs since version 20.2. It was also bundled and pre-installed with XEmacs 19.16–20.x. XEmacs 21.x users want to install the corresponding plugin package which is available from the XEmacs ftp site. See the XEmacs 21.x documentation on package installation for details.
Users of earlier Emacs distributions (including Emacs 19) can get a RefTeX distribution from the RefTeX web page. Note that the Emacs 19 version supports many but not all features described in this manual.

Finally thanks to Uwe Bolick who first got me interested in supporting LaTeX labels and references with an editor (which was MicroEmacs at the time).
Here is a summary of RefTeX's commands which can be executed from
LaTeX files. Command which are executed from the special buffers are
not described here. All commands are available from the Ref
menu. See See Key Bindings.
Show the table of contents for the current document. When called with one ore two C-u prefixes, rescan the document first.
Insert a unique label. With one or two C-u prefixes, enforce document rescan first.
Start a selection process to select a label, and insert a reference to it. With one or two C-u prefixes, enforce document rescan first.
Make a citation using BibTeX database files. After prompting for a regular expression, scans the buffers with BibTeX entries (taken from the
\bibliographycommand or athebibliographyenvironment) and offers the matching entries for selection. The selected entry is formatted according toreftex-cite-formatand inserted into the buffer.
When called with a C-u prefix, prompt for optional arguments in cite macros. When called with a numeric prefix, make that many citations. When called with point inside the braces of a\citecommand, it will add another key, ignoring the value ofreftex-cite-format.
The regular expression uses an expanded syntax: `&&' is interpreted asand. Thus, `aaaa&&bbb' matches entries which contain both `aaaa' and `bbb'. While entering the regexp, completion on knows citation keys is possible. `=' is a good regular expression to match all entries in all files.
Query for an index macro and insert it along with its arguments. The index macros available are those defined in
reftex-index-macroor by a call toreftex-add-index-macros, typically from an AUCTeX style file. RefTeX provides completion for the index tag and the index key, and will prompt for other arguments.
Put current selection or the word near point into the default index macro. This uses the information in
reftex-index-default-macroto make an index entry. The phrase indexed is the current selection or the word near point. When called with one C-u prefix, let the user have a chance to edit the index entry. When called with 2 C-u as prefix, also ask for the index macro and other stuff. When called inside TeX math mode as determined by the texmathp.el library which is part of AUCTeX, the string is first processed with thereftex-index-math-format, which see.
Add current selection or the word at point to the phrases buffer. When you are in transient-mark-mode and the region is active, the selection will be used - otherwise the word at point. You get a chance to edit the entry in the phrases buffer - to save the buffer and return to the LaTeX document, finish with C-c C-c.
Index all index phrases in the current region. This works exactly like global indexing from the index phrases buffer, but operation is restricted to the current region.
Display a buffer with an index compiled from the current document. When the document has multiple indices, first prompts for the correct one. When index support is turned off, offer to turn it on. With one or two C-u prefixes, rescan document first. With prefix 2, restrict index to current document section. With prefix 3, restrict index to active region.
View cross reference of macro at point. Point must be on the key argument. Works with the macros
\label,\ref,\cite,\bibitem,\indexand many derivatives of these. Where it makes sense, subsequent calls show additional locations. See also the variablereftex-view-crossref-extraand the commandreftex-view-crossref-from-bibtex. With one or two C-u prefixes, enforce rescanning of the document. With argument 2, select the window showing the cross reference.
View location in a LaTeX document which cites the BibTeX entry at point. Since BibTeX files can be used by many LaTeX documents, this function prompts upon first use for a buffer in RefTeX mode. To reset this link to a document, call the function with a prefix arg. Calling this function several times find successive citation locations.
Create TAGS file by running
etagson the current document. The TAGS file is also immediately visited withvisit-tags-table.
Run grep query through all files related to this document. With prefix arg, force to rescan document. No active TAGS table is required.
Regexp search through all files of the current document. Starts always in the master file. Stops when a match is found. No active TAGS table is required.
Run a query-replace-regexp of from with to over the entire document. With prefix arg, replace only word-delimited matches. No active TAGS table is required.
Toggle a minor mode which enables incremental search to work globally on the entire multifile document. Files will be searched in th sequence they appear in the document.
Prompt for a label (with completion) and jump to the location of this label. Optional prefix argument other-window goes to the label in another window.
Query replace from with to in all
\labeland\refcommands. Works on the entire multifile document. No active TAGS table is required.
Renumber all simple labels in the document to make them sequentially. Simple labels are the ones created by RefTeX, consisting only of the prefix and a number. After the command completes, all these labels will have sequential numbers throughout the document. Any references to the labels will be changed as well. For this, RefTeX looks at the arguments of any macros which either start or end with the string `ref'. This command should be used with care, in particular in multifile documents. You should not use it if another document refers to this one with the
xrpackage.
Create a new BibTeX database file with all entries referenced in document. The command prompts for a filename and writes the collected entries to that file. Only entries referenced in the current document with any
\cite-like macros are used. The sequence in the new file is the same as it was in the old database.
Parse the entire document in order to update the parsing information.
Enforce rebuilding of several internal lists and variables. Also removes the parse file associated with the current document.
Here is a complete list of RefTeX's configuration variables. All
variables have customize support - so if you are not familiar with Emacs
Lisp (and even if you are) you might find it more comfortable to use
customize to look at and change these variables. M-x
reftex-customize will get you there.
List of LaTeX commands which input another file. The file name is expected after the command, either in braces or separated by whitespace.
Maximum depth of section levels in document structure. Standard LaTeX needs 7, default is 12.
Commands and levels used for defining sections in the document. The
carof each cons cell is the name of the section macro. Thecdris a number indicating its level. A negative level means the same as the positive value, but the section will never get a number. Thecdrmay also be a function which then has to return the level. This list is also used for promotion and demotion of sectioning commands. If you are using a document class which has several sets of sectioning commands, promotion only works correctly if this list is sorted first by set, then within each set by level. The promotion commands always select the nearest entry with the correct new level.
The maximum level of toc entries which will be included in the TOC. Section headings with a bigger level will be ignored. In RefTeX, chapters are level 1, sections level 2 etc. This variable can be changed from within the *toc* buffer with the t key.
Non-
nilmeans,\partis like any other sectioning command. This means, part numbers will be included in the numbering of chapters, and chapter counters will be reset for each part. Whennil(the default), parts are special, do not reset the chapter counter and also do not show up in chapter numbers.
Non-
nilmeans, turn automatic recentering of *TOC* window on. When active, the *TOC* window will always show the section you are currently working in. Recentering happens whenever Emacs is idle for more thanreftex-idle-timeseconds.Value
tmeans, turn on immediately when RefTeX gets started. Then, recentering will work for any toc window created during the session.Value
frame(the default) means, turn automatic recentering on only while the dedicated TOC frame does exist, and do the recentering only in that frame. So when creating that frame (with d key in an ordinary TOC window), the automatic recentering is turned on. When the frame gets destroyed, automatic recentering is turned off again.This feature can be turned on and off from the menu (Ref->Options).
Non-
nilmeans, create TOC window by splitting window horizontally. The default is to split vertically.
Fraction of the width or height of the frame to be used for TOC window.
Non-
nilmeans, split the selected window to display the *toc* buffer. This helps to keep the window configuration, but makes the *toc* small. Whennil, all other windows except the selected one will be deleted, so that the *toc* window fills half the frame.
Non-
nilmeans, include file boundaries in *toc* buffer. This flag can be toggled from within the *toc* buffer with the i key.
Non-
nilmeans, include labels in *toc* buffer. This flag can be toggled from within the *toc* buffer with the l key.
Non-
nilmeans, include index entries in *toc* buffer. This flag can be toggled from within the *toc* buffer with the i key.
Non-
nilmeans, include context with labels in the *toc* buffer. Context will only be shown if the labels are visible as well. This flag can be toggled from within the *toc* buffer with the c key.
Non-
nilmeans, point in *toc* buffer (the table-of-contents buffer) will cause other window to follow. The other window will show the corresponding part of the document. This flag can be toggled from within the *toc* buffer with the f key.
Default label alist specifications. It is a list of symbols with associations in the constant
reftex-label-alist-builtin.LaTeXshould always be the last entry.
Set this variable to define additions and changes to the defaults in
reftex-default-label-alist-entries. The only things you must not change is that?sis the type indicator for section labels, and <SPC> for theanylabel type. These are hard-coded at other places in the code.The value of the variable must be a list of items. Each item is a list itself and has the following structure:
(env-or-macro type-key label-prefix reference-format context-method (magic-word ... ) toc-level)Each list entry describes either an environment carrying a counter for use with
\labeland\ref, or a LaTeX macro defining a label as (or inside) one of its arguments. The elements of each list entry are:
- env-or-macro
- Name of the environment (like `table') or macro (like `\myfig'). For macros, indicate the arguments, as in `\myfig[]{}{}{*}{}'. Use square brackets for optional arguments, a star to mark the label argument, if any. The macro does not have to have a label argument - you could also use `\label{...}' inside one of its arguments.
Special names:
sectionfor section labels,anyto define a group which contains all labels.This may also be a function to do local parsing and identify point to be in a non-standard label environment. The function must take an argument bound and limit backward searches to this value. It should return either nil or a cons cell
(function.position)with the function symbol and the position where the special environment starts. See the Info documentation for an example.Finally this may also be
nilif the entry is only meant to change some settings associated with the type indicator character (see below).- type-key
- Type indicator character, like
?t, must be a printable ASCII character. The type indicator is a single character which defines a label type. Any label inside the environment or macro is assumed to belong to this type. The same character may occur several times in this list, to cover cases in which different environments carry the same label type (likeequationandeqnarray). If the type indicator isniland the macro has a label argument `{*}', the macro defines neutral labels just like\label. In this case the reminder of this entry is ignored.- label-prefix
- Label prefix string, like `tab:'. The prefix is a short string used as the start of a label. It may be the empty string. The prefix may contain the following `%' escapes:
%f Current file name, directory and extension stripped. %F Current file name relative to master file directory. %m Master file name, directory and extension stripped. %M Directory name (without path) where master file is located. %u User login name, on systems which support this. %S A section prefix derived with variablereftex-section-prefixes.Example: In a file intro.tex, `eq:%f:' will become `eq:intro:'.
- reference-format
- Format string for reference insert in buffer. `%s' will be replaced by the label. When the format starts with `~', this `~' will only be inserted when the character before point is not a whitespace.
- context-method
- Indication on how to find the short context.
- If
nil, use the text following the `\label{...}' macro.- If
t, use
- the section heading for section labels.
- text following the `\begin{...}' statement of environments (not a good choice for environments like eqnarray or enumerate, where one has several labels in a single environment).
- text after the macro name (starting with the first arg) for macros.
- If an integer, use the nth argument of the macro. As a special case, 1000 means to get text after the last macro argument.
- If a string, use as regexp to search backward from the label. Context is then the text following the end of the match. E.g. putting this to `\\caption[[{]' will use the caption in a figure or table environment. `\\begin{eqnarray}\|\\\\' works for eqnarrays.
- If any of
caption,item,eqnarray-like,alignat-like, this symbol will internally be translated into an appropriate regexp (see also the variablereftex-default-context-regexps).- If a function, call this function with the name of the environment/macro as argument. On call, point will be just after the
\labelmacro. The function is expected to return a suitable context string. It should throw an exception (error) when failing to find context. As an example, here is a function returning the 10 chars following the label macro as context:(defun my-context-function (env-or-mac) (if (> (point-max) (+ 10 (point))) (buffer-substring (point) (+ 10 (point))) (error "Buffer too small")))Label context is used in two ways by RefTeX: For display in the label menu, and to derive a label string. If you want to use a different method for each of these, specify them as a dotted pair. E.g.
(nil . t)uses the text after the label (nil) for display, and text from the default position (t) to derive a label string. This is actually used for section labels.- magic-word-list
- List of magic words which identify a reference to be of this type. If the word before point is equal to one of these words when calling
reftex-reference, the label list offered will be automatically restricted to labels of the correct type. If the first element of this word–list is the symbol `regexp', the strings are interpreted as regular expressions.- toc-level
- The integer level at which this environment should be added to the table of contents. See also
reftex-section-levels. A positive value will number the entries mixed with the sectioning commands of the same level. A negative value will make unnumbered entries. Useful only for theorem-like environments which structure the document. Will be ignored for macros. When omitted ornil, no TOC entries will be made.If the type indicator characters of two or more entries are the same, RefTeX will use
- the first non-
nilformat and prefix- the magic words of all involved entries.
Any list entry may also be a symbol. If that has an association in
reftex-label-alist-builtin, thecddrof that association is spliced into the list. However, builtin defaults should normally be set with the variablereftex-default-label-alist-entries.
Prefixes for section labels. When the label prefix given in an entry in
reftex-label-alistcontains `%S', this list is used to determine the correct prefix string depending on the current section level. The list is an alist, with each entry of the form(key.prefix). Possible keys are sectioning macro names like `chapter', integer section levels (as given inreftex-section-levels), andtfor the default.
Alist with default regular expressions for finding context. The emacs lisp form
(format regexp (regexp-quote environment))is used to calculate the final regular expression - so `%s' will be replaced with the environment or macro.
Non-
nilmeans, trust the label prefix when determining label type. It is customary to use special label prefixes to distinguish different label types. The label prefixes have no syntactic meaning in LaTeX (unless special packages like fancyref) are being used. RefTeX can and by default does parse around each label to detect the correct label type, but this process can be slow when a document contains thousands of labels. If you use label prefixes consistently, you may speed up document parsing by setting this variable to a non-nil value. RefTeX will then compare the label prefix with the prefixes found in `reftex-label-alist' and derive the correct label type in this way. Possible values for this option are:t This means to trust any label prefixes found. regexp If a regexp, only prefixes matched by the regexp are trusted. list List of accepted prefixes, as strings. The colon is part of the prefix, e.g. ("fn:" "eqn:" "item:"). nil Never trust a label prefix.The only disadvantage of using this feature is that the label context displayed in the label selection buffer along with each label is simply some text after the label definition. This is no problem if you place labels keeping this in mind (e.g. before the equation, at the beginning of a fig/tab caption ...). Anyway, it is probably best to use the regexp or the list value types to fine-tune this feature. For example, if your document contains thousands of footnotes with labels fn:xxx, you may want to set this variable to the value "^fn:$" or ("fn:"). Then RefTeX will still do extensive parsing for any non-footnote labels.
Flags governing label insertion. The value has the form
(derive prompt)If deriveis
t, RefTeX will try to derive a sensible label from context. A section label for example will be derived from the section heading. The conversion of the context to a valid label is governed by the specifications given inreftex-derive-label-parameters. If derive isnil, the default label will consist of the prefix and a unique number, like `eq:23'.If prompt is
t, the user will be prompted for a label string. When prompt isnil, the default label will be inserted without query.So the combination of derive and prompt controls label insertion. Here is a table describing all four possibilities:
derive prompt action ----------------------------------------------------------- nil nil Insert simple label, like `eq:22' or `sec:13'. No query. nil t Prompt for label. t nil Derive a label from context and insert. No query. t t Derive a label from context, prompt for confirmation.Each flag may be set to
t,nil, or a string of label type letters indicating the label types for which it should be true. Thus, the combination may be set differently for each label type. The default settings `"s"' and `"sft"' mean: Derive section labels from headings (with confirmation). Prompt for figure and table labels. Use simple labels without confirmation for everything else.The available label types are:
s(section),f(figure),t(table),i(item),e(equation),n(footnote),N(endnote) plus any definitions inreftex-label-alist.
If non-
nil, should be a function which produces the string to insert as a label definition. The function will be called with two arguments, the label and the default-format (usually `\label{%s}'). It should return the string to insert into the buffer.
Function to turn an arbitrary string into a valid label. RefTeX's default function uses the variable
reftex-derive-label-parameters.
Filter function which will process a context string before it is used to derive a label from it. The intended application is to convert ISO or Mule characters into something valid in labels. The default function
reftex-latin1-to-asciiremoves the accents from Latin-1 characters. X-Symbol (>=2.6) sets this variable to the much more generalx-symbol-translate-to-ascii.
Parameters for converting a string into a label. This variable is a list of the following items:
- nwords
- Number of words to use.
- maxchar
- Maximum number of characters in a label string.
- invalid
nil: Throw away any words containing characters invalid in labels.
t: Throw away only the invalid characters, not the whole word.- abbrev
nil: Never abbreviate words.
t: Always abbreviate words (seereftex-abbrev-parameters).
1: Abbreviate words if necessary to shorten label string.- separator
- String separating different words in the label.
- ignorewords
- List of words which should not be part of labels.
- downcase
t: Downcase words before putting them into the label.
Parameters for abbreviation of words. A list of four parameters.
- min-chars
- Minimum number of characters remaining after abbreviation.
- min-kill
- Minimum number of characters to remove when abbreviating words.
- before
- Character class before abbrev point in word.
- after
- Character class after abbrev point in word.
List of flags governing the label menu makeup. The flags are:
- table-of-contents
- Show the labels embedded in a table of context.
- section-numbers
- Include section numbers (like 4.1.3) in table of contents.
- counters
- Show counters. This just numbers the labels in the menu.
- no-context
- Non-
nilmeans do not show the short context.- follow
- Follow full context in other window.
- show-commented
- Show labels from regions which are commented out.
- match-everywhere
- Obsolete flag.
- show-files
- Show begin and end of included files.
Each of these flags can be set to
tornil, or to a string of type letters indicating the label types for which it should be true. These strings work like character classes in regular expressions. Thus, setting one of the flags to `"sf"' makes the flag true for section and figure labels,nilfor everything else. Setting it to `"^sf"' makes it the other way round.The available label types are:
s(section),f(figure),t(table),i(item),e(equation),n(footnote), plus any definitions inreftex-label-alist.Most options can also be switched from the label menu itself - so if you decide here to not have a table of contents in the label menu, you can still get one interactively during selection from the label menu.
Punctuation strings for multiple references. When marking is used in the selection buffer to select several references, this variable associates the 3 marking characters `,-+' with prefix strings to be inserted into the buffer before the corresponding
\refmacro. This is used to string together whole reference sets, like `eqs. 1,2,3-5,6 and 7' in a single call toreftex-reference.
Non-
nilmeans, the varioref macro\vrefis used as default. In the selection buffer, the v key toggles the reference macro between\refand\vref. The value of this variable determines the default which is active when entering the selection process. Instead ofnilort, this may also be a string of type letters indicating the label types for which it should be true.
Non-
nilmeans, the fancyref macro\frefis used as default. In the selection buffer, the V key toggles the reference macro between\ref,\frefand\Fref. The value of this variable determines the default which is active when entering the selection process. Instead ofnilort, this may also be a string of type letters indicating the label types for which it should be true.
If non-
nil, should be a function which produces the string to insert as a reference. Note that the insertion format can also be changed withreftex-label-alist. This hook also is used by the special commands to insert\vrefand\frefreferences, so even if you set this, your setting will be ignored by the special commands. The function will be called with two arguments, the label and the default-format (usually `~\ref{%s}'). It should return the string to insert into the buffer.
Non-
nilmeans,reftex-referencewill try to guess the label type. To do that, RefTeX will look at the word before the cursor and compare it with the magic words given inreftex-label-alist. When it finds a match, RefTeX will immediately offer the correct label menu - otherwise it will prompt you for a label type. If you set this variable tonil, RefTeX will always prompt for a label type.
Normal Hook which is run before context is displayed anywhere. Designed for
X-Symbol, but may have other uses as well.
X-Symbolspecific hook. Probably not useful for other purposes. The functions get two arguments, the buffer from where the command started and a symbol indicating in what context the hook is called.
Normal hook which is run when a selection buffer enters
reftex-select-label-mode.
The keymap which is active in the labels selection process (see Referencing Labels).
LaTeX commands which specify the BibTeX databases to use with the document.
List of regular expressions to exclude files in
\\bibliography{..}. File names matched by any of these regexps will not be parsed. Intended for files which contain only@stringmacro definitions and the like, which are ignored by RefTeX anyway.
List of BibTeX database files which should be used if none are specified. When
reftex-citationis called from a document with neither a `\bibliography{...}' statement nor athebibliographyenvironment, RefTeX will scan these files instead. Intended for usingreftex-citationin non-LaTeX files. The files will be searched along the BIBINPUTS or TEXBIB path.
Sorting of the entries found in BibTeX databases by reftex-citation. Possible values:
nil Do not sort entries. author Sort entries by author name. year Sort entries by increasing year. reverse-year Sort entries by decreasing year.
The format of citations to be inserted into the buffer. It can be a string, an alist or a symbol. In the simplest case this is just the string `\cite{%l}', which is also the default. See the definition of
reftex-cite-format-builtinfor more complex examples.If
reftex-cite-formatis a string, it will be used as the format. In the format, the following percent escapes will be expanded.
%l- The BibTeX label of the citation.
%a- List of author names, see also
reftex-cite-punctuation.%2a- Like %a, but abbreviate more than 2 authors like Jones et al.
%A- First author name only.
%e- Works like `%a', but on list of editor names. (`%2e' and `%E' work a well).
It is also possible to access all other BibTeX database fields:
%b booktitle %c chapter %d edition %h howpublished %i institution %j journal %k key %m month %n number %o organization %p pages %P first page %r address %s school %u publisher %t title %v volume %y year %B booktitle, abbreviated %T title, abbreviatedUsually, only `%l' is needed. The other stuff is mainly for the echo area display, and for
(setq reftex-comment-citations t).`%<' as a special operator kills punctuation and space around it after the string has been formatted.
A pair of square brackets indicates an optional argument, and RefTeX will prompt for the values of these arguments.
Beware that all this only works with BibTeX database files. When citations are made from the
\bibitemsin an explicitthebibliographyenvironment, only `%l' is available.If
reftex-cite-formatis an alist of characters and strings, the user will be prompted for a character to select one of the possible format strings.In order to configure this variable, you can either set
reftex-cite-formatdirectly yourself or set it to the symbol of one of the predefined styles. The predefined symbols are those which have an association in the constantreftex-cite-format-builtin) E.g.:(setq reftex-cite-format 'natbib).
If non-
nil, should be a function which produces the string to insert as a citation. Note that the citation format can also be changed with the variablereftex-cite-format. The function will be called with two arguments, the citation-key and the default-format (taken fromreftex-cite-format). It should return the string to insert into the buffer.
Non-
nilmeans, prompt for empty optional arguments in cite macros. When an entry inreftex-cite-formatist given with square brackets to indicate optional arguments (for example `\\cite[][]{%l}'), RefTeX can prompt for values. Possible values are:nil Never prompt for optional arguments t Always prompt maybe Prompt only ifreftex-citationwas called with C-u prefix argUnnecessary empty optional arguments are removed before insertion into the buffer. See
reftex-cite-cleanup-optional-args.
Non-
nilmeans, remove empty optional arguments from cite macros if possible.
Non-
nilmeans add a comment for each citation describing the full entry. The comment is formatted according toreftex-cite-comment-format.
Citation format used for commented citations. Must not contain `%l'. See the variable
reftex-cite-formatfor possible percent escapes.
Punctuation for formatting of name lists in citations. This is a list of 3 strings.
- normal names separator, like `, ' in Jones, Brown and Miller
- final names separator, like ` and ' in Jones, Brown and Miller
- The `et al.' string, like ` {\it et al.}' in Jones {\it et al.}
Normal hook which is run when a selection buffer enters
reftex-select-bib-mode.
The keymap which is active in the citation-key selection process (see Creating Citations).
Non-
nilmeans, index entries are parsed as well. Index support is resource intensive and the internal structure holding the parsed information can become quite big. Therefore it can be turned off. When this isniland you execute a command which requires index support, you will be asked for confirmation to turn it on and rescan the document.
List of special characters in index entries, given as strings. These correspond to the
MakeIndexkeywords(level encap actual quote escape).
List of macros which define index entries. The structure of each entry is
(macro index-tag key prefix exclude repeat)macro is the macro. Arguments should be denoted by empty braces, as for example in `\index[]{*}'. Use square brackets to denote optional arguments. The star marks where the index key is.
index-tag is a short name of the index. `idx' and `glo' are reserved for the default index and the glossary. Other indices can be defined as well. If this is an integer, the Nth argument of the macro holds the index tag.
key is a character which is used to identify the macro for input with
reftex-index. `?i', `?I', and `?g' are reserved for default index and glossary.prefix can be a prefix which is added to the key part of the index entry. If you have a macro
\newcommand{\molec}[1]{#1\index{Molecules!#1}, this prefix should be `Molecules!'.exclude can be a function. If this function exists and returns a non-
nilvalue, the index entry at point is ignored. This was implemented to support the (deprecated) `^' and `_' shortcuts in the LaTeX2eindexpackage.repeat, if non-
nil, means the index macro does not typeset the entry in the text, so that the text has to be repeated outside the index macro. Needed forreftex-index-selection-or-wordand for indexing from the phrase buffer.The final entry may also be a symbol. It must have an association in the variable
reftex-index-macros-builtinto specify the main indexing package you are using. Valid values are currentlydefault The LaTeX default - unnecessary to specify this one multind The multind.sty package index The index.sty package index-shortcut The index.sty packages with the ^ and _ shortcuts. Should not be used - only for old documentsNote that AUCTeX sets these things internally for RefTeX as well, so with a sufficiently new version of AUCTeX, you should not set the package here.
The default index macro for
reftex-index-selection-or-word. This is a list with(macro-key default-tag).macro-key is a character identifying an index macro - see
reftex-index-macros.default-tag is the tag to be used if the macro requires a tag argument. When this is
niland a tag is needed, RefTeX will ask for it. When this is the empty string and the TAG argument of the index macro is optional, the TAG argument will be omitted.
Default index tag. When working with multiple indexes, RefTeX queries for an index tag when creating index entries or displaying a specific index. This variable controls the default offered for these queries. The default can be selected with <RET> during selection or completion. Valid values of this variable are:
nil Do not provide a default index "tag" The default index tag given as a string, e.g. "idx" last The last used index tag will be offered as default
Format of index entries when copied from inside math mode. When
reftex-index-selection-or-wordis executed inside TeX math mode, the index key copied from the buffer is processed with this format string through theformatfunction. This can be used to add the math delimiters (e.g. `$') to the string. Requires the texmathp.el library which is part of AUCTeX.
File extension for the index phrase file. This extension will be added to the base name of the master file.
Regexp matching the `and' operator for index arguments in phrases file. When several index arguments in a phrase line are separated by this operator, each part will generate an index macro. So each match of the search phrase will produce several different index entries. Make sure this does no match things which are not separators. This logical `and' has higher priority than the logical `or' specified in
reftex-index-phrases-logical-or-regexp.
Regexp matching the `or' operator for index arguments in phrases file. When several index arguments in a phrase line are separated by this operator, the user will be asked to select one of them at each match of the search phrase. The first index arg will be the default. A number key 1–9 must be pressed to switch to another. Make sure this does no match things which are not separators. The logical `and' specified in
reftex-index-phrases-logical-or-regexphas higher priority than this logical `or'.
Non-
nilmeans phrases search will look for whole words, not subwords. This works by requiring word boundaries at the beginning and end of the search string. When the search phrase already has a non-word-char at one of these points, no word boundary is required there.
Non-
nilmeans, searching for index phrases will ignore case.
A function which is called at each match during global indexing. If the function returns nil, the current match is skipped.
Non-
nilmeans, skip matches which appear to be indexed already. When doing global indexing from the phrases buffer, searches for some phrases may match at places where that phrase was already indexed. In particular when indexing an already processed document again, this will even be the norm. When this variable is non-nil, RefTeX checks if the match is an index macro argument, or if an index macro is directly before or after the phrase. If that is the case, that match will be ignored.
Non-
nilmeans, when indexing from the phrases buffer, wrap lines. Inserting indexing commands in a line makes the line longer - often so long that it does not fit onto the screen. When this variable is non-nil, newlines will be added as necessary before and/or after the indexing command to keep lines short. However, the matched text phrase and its index command will always end up on a single line.
Non-
nilmeans when sorting phrase lines, the explicit index entry is used. Phrase lines in the phrases buffer contain a search phrase, and sorting is normally based on these. Some phrase lines also have an explicit index argument specified. When this variable is non-nil, the index argument will be used for sorting.
Non-
nilmeans, empty and comment lines separate phrase buffer into blocks. Sorting will then preserve blocks, so that lines are re-arranged only within blocks.
Normal hook which is run when a buffer is put into
reftex-index-phrases-mode.
The letters which denote sections in the index. Usually these are all capital letters. Don't use any downcase letters. Order is not significant, the index will be sorted by whatever the sort function thinks is correct. In addition to these letters, RefTeX will create a group `!' which contains all entries sorted below the lowest specified letter. In the *Index* buffer, pressing any of these capital letters or ! will jump to that section.
Non-
nilmeans, display the index definition context in the *Index* buffer. This flag may also be toggled from the *Index* buffer with the c key.
Non-
nilmeans, point in *Index* buffer will cause other window to follow. The other window will show the corresponding part of the document. This flag can be toggled from within the *Index* buffer with the f key.
Macros which can be used for the display of cross references. This is used when `reftex-view-crossref' is called with point in an argument of a macro. Note that crossref viewing for citations, references (both ways) and index entries is hard-coded. This variable is only to configure additional structures for which crossreference viewing can be useful. Each entry has the structure
(macro-re search-re highlight).macro-re is matched against the macro. search-re is the regexp used to search for cross references. `%s' in this regexp is replaced with the macro argument at point. highlight is an integer indicating which subgroup of the match should be highlighted.
Non-
nilmeans, initially turn automatic viewing of crossref info on. Automatic viewing of crossref info normally uses the echo area. Whenever point is idle for more thanreftex-idle-timeseconds on the argument of a\refor\citemacro, and no other message is being displayed, the echo area will display information about that cross reference. You can also set the variable to the symbolwindow. In this case a small temporary window is used for the display. This feature can be turned on and off from the menu (Ref->Options).
Time (secs) Emacs has to be idle before automatic crossref display or toc recentering is done.
Citation format used to display citation info in the message area. See the variable
reftex-cite-formatfor possible percent escapes.
Non-
nilmeans, automatic citation display will revisit files if necessary. When nil, citation display in echo area will only be active for cached echo strings (seereftex-cache-cite-echo), or for BibTeX database files which are already visited by a live associated buffers.
Non-
nilmeans, the information displayed in the echo area for cite macros (see variablereftex-auto-view-crossref) is cached and saved along with the parsing information. The cache survives document scans. In order to clear it, use M-x reftex-reset-mode.
List of specifications how to retrieve the search path for TeX files. Several entries are possible.
Multiple directories can be separated by the system dependent
- If an element is the name of an environment variable, its content is used.
- If an element starts with an exclamation mark, it is used as a command to retrieve the path. A typical command with the kpathsearch library would be
"!kpsewhich -show-path=.tex".- Otherwise the element itself is interpreted as a path.
path-separator. Directories ending in `//' or `!!' will be expanded recursively. See alsoreftex-use-external-file-finders.
List of specifications how to retrieve the search path for BibTeX files. Several entries are possible.
Multiple directories can be separated by the system dependent
- If an element is the name of an environment variable, its content is used.
- If an element starts with an exclamation mark, it is used as a command to retrieve the path. A typical command with the kpathsearch library would be
"!kpsewhich -show-path=.bib".- Otherwise the element itself is interpreted as a path.
path-separator. Directories ending in `//' or `!!' will be expanded recursively. See alsoreftex-use-external-file-finders.
Association list with file extensions for different file types. This is a list of items, each item is like:
(type. (def-ext other-ext...))type: File type like"bib"or"tex". def-ext: The default extension for that file type, like".tex"or".bib". other-ext: Any number of other valid extensions for this file type.When a files is searched and it does not have any of the valid extensions, we try the default extension first, and then the naked file name.
Non-
nilmeans, search all specified directories before trying recursion. Thus, in a path `.//:/tex/', search first `./', then `/tex/', and then all subdirectories of `./'. If this option isnil, the subdirectories of `./' are searched before `/tex/'. This is mainly for speed - most of the time the recursive path is for the system files and not for the user files. Set this tonilif the default makes RefTeX finding files with equal names in wrong sequence.
Non-
nilmeans, use external programs to find files. Normally, RefTeX searches the paths given in the environment variablesTEXINPUTSandBIBINPUTSto find TeX files and BibTeX database files. With this option turned on, it calls an external program specified in the optionreftex-external-file-findersinstead. As a side effect, the variablesreftex-texpath-environment-variablesandreftex-bibpath-environment-variableswill be ignored.
Association list with external programs to call for finding files. Each entry is a cons cell
(type.program). type is either"tex"or"bib". program is a string containing the external program to use with any arguments.%fwill be replaced by the name of the file to be found. Note that these commands will be executed directly, not via a shell. Only relevant whenreftex-use-external-file-findersis non-nil.
Non-
nilmeans, keep buffers created for parsing and lookup. RefTeX sometimes needs to visit files related to the current document. We distinguish files visited forThe created buffers can be kept for later use, or be thrown away immediately after use, depending on the value of this variable:
- PARSING
- Parts of a multifile document loaded when (re)-parsing the document.
- LOOKUP
- BibTeX database files and TeX files loaded to find a reference, to display label context, etc.
nil- Throw away as much as possible.
t- Keep everything.
1- Throw away buffers created for parsing, but keep the ones created for lookup.
If a buffer is to be kept, the file is visited normally (which is potentially slow but will happen only once). If a buffer is to be thrown away, the initialization of the buffer depends upon the variable
reftex-initialize-temporary-buffers.
Non-
nilmeans do initializations even when visiting file temporarily. Whennil, RefTeX may turn off find-file hooks and other stuff to briefly visit a file. Whent, the full default initializations are done (find-file-hooketc.). Instead oftornil, this variable may also be a list of hook functions to do a minimal initialization.
List of regular expressions to exclude certain input files from parsing. If the name of a file included via
\includeor\inputis matched by any of the regular expressions in this list, that file is not parsed by RefTeX.
Non-
nilmeans, re-parse only 1 file when asked to re-parse. Re-parsing is normally requested with a C-u prefix to many RefTeX commands, or with the r key in menus. When this option istin a multifile document, we will only parse the current buffer, or the file associated with the label or section heading near point in a menu. Requesting re-parsing of an entire multifile document then requires a C-u C-u prefix or the capital R key in menus.
Non-
nilmeans, save information gathered with parsing in files. The file MASTER.rel in the same directory as MASTER.tex is used to save the information. When this variable ist,
- accessing the parsing information for the first time in an editing session will read that file (if available) instead of parsing the document.
- exiting Emacs or killing a buffer in reftex-mode will cause a new version of the file to be written.
File extension for the file in which parser information is stored. This extension is added to the base name of the master file.
Non-
nilmeans, RefTeX may rescan the document when this seems necessary. Applies (currently) only in rare cases, when a new label cannot be placed with certainty into the internal label list.
Non-
nilmeans use a separate selection buffer for each label type. These buffers are kept from one selection to the next and need not to be created for each use - so the menu generally comes up faster. The selection buffers will be erased (and therefore updated) automatically when new labels in its category are added. See the variablereftex-auto-update-selection-buffers.
Non-
nilmeans, selection buffers will be updated automatically. When a new label is defined withreftex-label, all selection buffers associated with that label category are emptied, in order to force an update upon next use. Whennil, the buffers are left alone and have to be updated by hand, with the g key from the label selection process. The value of this variable will only have any effect whenreftex-use-multiple-selection-buffersis non-nil.
Non-
nilmeans, use fonts in label menu and on-the-fly help. Font-lock must be loaded as well to actually get fontified display. After changing this option, a rescan may be necessary to activate it.
Non-
nilmeans, re-fontify the context in the label menu with font-lock. This slightly slows down the creation of the label menu. It is only necessary when you definitely want the context fontified.This option may have 3 different values:
The option is ignored when
nil- Never refontify.
t- Always refontify.
1- Refontify when necessary, e.g. with old versions of the x-symbol package.
reftex-use-fontsisnil.
Non-
nilmeans, highlight selected text in selection and *toc* buffers. Normally, the text near the cursor is the selected text, and it is highlighted. This is the entry most keys in the selection and *toc* buffers act on. However, if you mainly use the mouse to select an item, you may find it nice to have mouse-triggered highlighting instead or as well. The variable may have one of these values:nil No highlighting. cursor Highlighting is cursor driven. mouse Highlighting is mouse driven. both Both cursor and mouse trigger highlighting.Changing this variable requires to rebuild the selection and *toc* buffers to become effective (keys g or r).
Face name to highlight cursor selected item in toc and selection buffers. See also the variable
reftex-highlight-selection.
Face name to highlight mouse selected item in toc and selection buffers. See also the variable
reftex-highlight-selection.
Face name for section headings in toc and selection buffers.
Face name for bibliographic information in bib selection buffer.
Face name for the start of a new letter section in the index.
Non-
nilmeans, make additional key bindings on startup. These extra bindings are located in the users `C-c letter' map. See Key Bindings.
Plug-in flags for AUCTeX interface. This variable is a list of 5 boolean flags. When a flag is non-
nil, RefTeX will- supply labels in new sections and environments (flag 1) - supply arguments for macros like\label(flag 2) - supply arguments for macros like\ref(flag 3) - supply arguments for macros like\cite(flag 4) - supply arguments for macros like\index(flag 5)You may also set the variable itself to t or nil in order to turn all options on or off, respectively.
Supplying labels in new sections and environments applies when creating sections with C-c C-s and environments with C-c C-e.
Supplying macro arguments applies when you insert such a macro interactively with C-c <RET>.
See the AUCTeX documentation for more information.
Non-
nilmeans, follow-mode will revisit files if necessary. When nil, follow-mode will be suspended for stuff in unvisited files.
Non-
nilmeans, allow arguments of macros to be detached by whitespace. When this ist, the `aaa' in `\bbb [xxx] {aaa}' will be considered an argument of\bb. Note that this will be the case even if\bbis defined with zero or one argument.
RefTeX has the usual general keymap and load– and mode-hook.
Furthermore, the 4 modes used for referencing labels, creating citations, the table of contents buffer and the phrases buffer have their own keymaps and mode hooks. See the respective sections. There are many more hooks which are described in the relevant sections about options for a specific part of RefTeX.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
The purpose of this License is to make a manual, textbook, or other functional and useful document “free” in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.
This License is a kind of “copyleft,” which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.
We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.
This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The “Document,” below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as “you.” You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.
A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.
A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.
The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.
A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque.”
Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.
The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.
A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as “Acknowledgements,” “Dedications,” “Endorsements,” or “History.”) To “Preserve the Title” of such a section when you modify the Document means that it remains a section “Entitled XYZ” according to this definition.
The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.
You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and you may publicly display copies.
If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.
You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:
A. Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document). You may use the same title as a previous version
if the original publisher of that version gives permission.
B. List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
C. State on the Title page the name of the publisher of the
Modified Version, as the publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
F. Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled “History,” Preserve its Title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page. If
there is no section Entitled “History” in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
J. Preserve the network location, if any, given in the Document for
public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions
it was based on. These may be placed in the “History” section.
You may omit a network location for a work that was published at
least four years before the Document itself, or if the original
publisher of the version it refers to gives permission.
K. For any section Entitled “Acknowledgements” or “Dedications,”
Preserve the Title of the section, and preserve in the section all
the substance and tone of each of the contributor acknowledgements
and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles. Section numbers
or the equivalent are not considered part of the section titles.
M. Delete any section Entitled “Endorsements.” Such a section
may not be included in the Modified Version.
N. Do not retitle any existing section to be Entitled “Endorsements”
or to conflict in title with any Invariant Section.
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all
of these sections as invariant. To do this, add their titles to the
list of Invariant Sections in the Modified Version's license notice.
These titles must be distinct from any other section titles.
You may add a section Entitled “Endorsements,” provided it contains nothing but endorsements of your Modified Version by various parties–for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.
You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements,” and any sections Entitled “Dedications.” You must delete all sections Entitled “Endorsements.”
You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.
If a section in the Document is Entitled “Acknowledgements,” “Dedications,” or “History,” the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.
You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version” applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation.
To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:
Copyright (C) year your name.
Permission is granted to copy, distribute and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.2
or any later version published by the Free Software Foundation;
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
A copy of the license is included in the section entitled ``GNU
Free Documentation License.''
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with...Texts.” line with this:
with the Invariant Sections being list their titles, with the
Front-Cover Texts being list, and with the Back-Cover Texts being
list.
If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.
If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
