6.6 Finding Files
In order to find files included in a document via
\include, RefTeX searches all directories specified in the
TEXINPUTS. Similarly, it will search the
path specified in the variables
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:
Most TeX system have a default search path for both TeX files and BibTeX
files which is defined in some setup file. Usually this default path is
for system files which RefTeX does not need to see. But if your
document needs TeX files or BibTeX database files in a directory only
given in the default search path, RefTeX will fail to find them.
Some TeX systems do not use environment variables at all in order to
specify the search path. Both default and user search path are then
defined in setup files.
There are three ways to solve this problem:
Specify all relevant directories explicitly in the environment
variables. If for some reason you don't want to mess with the default
BIBINPUTS, define your own
variables and configure RefTeX to use them instead:
(setq reftex-texpath-environment-variables '("MYTEXINPUTS"))
(setq reftex-bibpath-environment-variables '("MYBIBINPUTS"))
Specify the full search path directly in RefTeX's variables.
Some TeX systems provide stand-alone programs to do the file search just
like TeX and BibTeX. E.g. Thomas Esser's
teTeX uses the
kpathsearch library which provides the command
to search for files. RefTeX can be configured to use this
program. Note that the exact syntax of the
command depends upon the version of that program.
(setq reftex-use-external-file-finders t)
'(("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:
'(("nw" "tex" ".tex" ".ltx") ("bib" ".bib")))
'( "nw" "tex" "sty" "cls" "ltx" "texi" "texinfo"))
