4.1.2 Selecting and Executing a Command

Once you started the command selection with C-c C-c, C-c C-r or C-c C-b you will be prompted for the type of command. AUCTeX will try to guess which command is appropriate in the given situation and propose it as default. Usually this is a processor like ‘TeX’ or ‘LaTeX’ if the document was changed or a viewer if the document was just typeset. Other commands can be selected in the minibuffer with completion support by typing <TAB>.

The available commands are defined by the variable TeX-command-list. Per default it includes commands for typesetting the document (e.g. ‘LaTeX’), for viewing the output (‘View’), for printing (‘Print’), for generating an index (‘Index’) or for spell checking (‘Spell’) to name but a few. You can also add your own commands by adding entries to TeX-command-list. Refer to its doc string for information about its syntax. You might also want to look at TeX-expand-list to learn about the expanders you can use in TeX-command-list.

Note that the default of the variable occasionally changes. Therefore it is advisable to add to the list rather than overwriting it. You can do this with a call to add-to-list in your init file. For example, if you wanted to add a command for running a program called ‘foo’ on the master or region file, you could do this with the following form.

(eval-after-load "tex"
  '(add-to-list 'TeX-command-list
		'("Foo" "foo %s" TeX-run-command t t :help "Run foo") t))

As mentioned before, AUCTeX will try to guess what command you want to invoke. If you want to use another command than ‘TeX’, ‘LaTeX’ or whatever processor AUCTeX thinks is appropriate for the current mode, set the variable TeX-command-default. You can do this for all files by setting it in a mode hook or per file by specifying it as a file variable (see (emacs)File Variables section ‘File Variables’ in The Emacs Editor).

User Option: TeX-command-default

The default command to run in this buffer. Must be an entry in TeX-command-list.

In case you use biblatex in a document, when automatic parsing is enabled AUCTeX checks the value of ‘backend’ option given to biblatex at load time to decide whether to use BibTeX or Biber for bibliography processing. Should AUCTeX fail to detect the right backend, you can use the file local LaTeX-biblatex-use-Biber variable.

Variable: LaTeX-biblatex-use-Biber

If this boolean variable is set as file local, it tells to AUCTeX whether to use Biber with biblatex. In this case, the autodetection of the biblatex backend will be overridden. You may want to set locally this variable if automatic parsing is not enabled.

After confirming a command to execute, AUCTeX will try to save any buffers related to the document, and check if the document needs to be reformatted. If the variable TeX-save-query is non-nil, AUCTeX will query before saving each file. By default AUCTeX will check emacs buffers associated with files in the current directory, in one of the TeX-macro-private directories, and in the TeX-macro-global directories. You can change this by setting the variable TeX-check-path.

User Option: TeX-check-path

Directory path to search for dependencies.

If nil, just check the current file. Used when checking if any files have changed.
