There are some options you can customize affecting which processors are invoked or the way this is done and which output they produce as a result. These options control if DVI or PDF output should be produced, if TeX should be started in interactive or nonstop mode, if source specials or a SyncTeX file should be produced for making inverse and forward search possible or which TeX engine should be used instead of regular TeX, like PDFTeX, Omega or XeTeX.
(C-c C-t C-p)
This command toggles the PDF mode of AUCTeX, a buffer-local
minor mode which is enabled by default. You can customize
TeX-PDF-mode
to give it a different default or set it as a file
local variable on a per-document basis. This option usually results in
calling either PDFTeX or ordinary TeX.
If this is set, DVI will also be produced by calling
PDFTeX, setting \pdfoutput=0
. This makes it possible to use
PDFTeX features like character protrusion even when producing
DVI files. Contemporary TeX distributions do this anyway,
so that you need not enable the option within AUCTeX.
(C-c C-t C-i) This command toggles the interactive mode of
AUCTeX, a global minor mode. You can customize
TeX-interactive-mode
to give it a different default. In
interactive mode, TeX will pause with an error prompt when errors are
encountered and wait for the user to type something.
(C-c C-t C-s) Toggles support for forward and inverse search. Forward search refers to jumping to the place in the previewed document corresponding to where point is located in the document source and inverse search to the other way round. See I/O Correlation.
You can permanently activate TeX-source-correlate-mode
by
customizing the variable TeX-source-correlate-mode
. There is a
bunch of customization options for the mode, use M-x
customize-group RET TeX-view RET to find out more.
AUCTeX is aware of three different means to do I/O correlation:
source specials (only DVI output), the pdfsync LaTeX package (only
PDF output) and SyncTeX. The choice between source specials and
SyncTeX can be controlled with the variable
TeX-source-correlate-method
.
Should you use source specials it has to be stressed very strongly however, that source specials can cause differences in page breaks and spacing, can seriously interfere with various packages and should thus never be used for the final version of a document. In particular, fine-tuning the page breaks should be done with source specials switched off.
AUCTeX also allows you to easily select different TeX engines for
processing, either by using the entries in the ‘TeXing Options’
submenu below the ‘Command’ menu or by calling the function
TeX-engine-set
. These eventually set the variable
TeX-engine
which you can also modify directly.
This variable allows you to choose which TeX engine should be used
for typesetting the document, i.e. the executables which will be used
when you invoke the ‘TeX’ or ‘LaTeX’ commands. The value
should be one of the symbols defined in TeX-engine-alist-builtin
or TeX-engine-alist
. The symbols ‘default’, ‘xetex’,
‘luatex’ and ‘omega’ are available from the built-in list.
Note that TeX-engine
is buffer-local, so setting the variable
directly or via the above mentioned menu or function will not take
effect in other buffers. If you want to activate an engine for all
AUCTeX modes, set TeX-engine
in your init file, e.g. by using
M-x customize-variable <RET>. If you want to activate it for a
certain AUCTeX mode only, set the variable in the respective mode
hook. If you want to activate it for certain files, set it through file
variables (see File Variables in The Emacs Editor).
Should you need to change the executable names related to the different
engine settings, there are some variables you can tweak. Those are
TeX-command
, LaTeX-command
, TeX-Omega-command
,
LaTeX-Omega-command
, ConTeXt-engine
and
ConTeXt-Omega-engine
. The rest of the executables is defined
directly in TeX-engine-alist-builtin
. If you want to override an
entry from that, add an entry to TeX-engine-alist
that starts
with the same symbol as that the entry in the built-in list and specify
the executables you want to use instead. You can also add entries to
TeX-engine-alist
in order to add support for engines not covered
per default.
Alist of TeX engines and associated commands. Each entry is a list with a maximum of five elements. The first element is a symbol used to identify the engine. The second is a string describing the engine. The third is the command to be used for plain TeX. The fourth is the command to be used for LaTeX. The fifth is the command to be used for the ‘--engine’ parameter of ConTeXt’s ‘texexec’ program. Each command can either be a variable or a string. An empty string or nil means there is no command available.
As shown above, AUCTeX handles in a special way most of the main
options that can be given to the TeX processors. When you need to
pass to the TeX processor arbitrary options not handled by AUCTeX,
you can use the file local variable TeX-command-extra-options
.
String with the extra options to be given to the TeX processor. For example, if you need to enable the shell escape feature to compile a document, add the following line to the list of local variables of the source file:
%%% TeX-command-extra-options: "-shell-escape"
By default this option is not safe as a file-local variable because a specially crafted document compiled with shell escape enabled can be used for malicious purposes.
You can customize AUCTeX to show the processor output as it is produced.
If non-nil, the output of TeX compilation is shown in another window.
