219 If #+LATEX_CLASS is set in the buffer, use its value and the
220 associated information. Here is the structure of each cell:
224 \(numbered-section . unnumbered-section)
230 The HEADER-STRING is the header that will be inserted into the
231 LaTeX file. It should contain the \\documentclass macro, and
232 anything else that is needed for this setup. To this header, the
233 following commands will be added:
235 - Calls to \\usepackage for all packages mentioned in the
236 variables `org-latex-default-packages-alist' and
237 `org-latex-packages-alist'. Thus, your header definitions
238 should avoid to also request these packages.
240 - Lines specified via \"#+LATEX_HEADER:\" and
241 \"#+LATEX_HEADER_EXTRA:\" keywords.
243 If you need more control about the sequence in which the header
244 is built up, or if you want to exclude one of these building
245 blocks for a particular class, you can use the following
246 macro-like placeholders.
248 [DEFAULT-PACKAGES] \\usepackage statements for default packages
249 [NO-DEFAULT-PACKAGES] do not include any of the default packages
250 [PACKAGES] \\usepackage statements for packages
251 [NO-PACKAGES] do not include the packages
252 [EXTRA] the stuff from #+LATEX_HEADER(_EXTRA)
253 [NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff
257 \\documentclass{article}
258 [NO-DEFAULT-PACKAGES]
260 \\providecommand{\\alert}[1]{\\textbf{#1}}
263 will omit the default packages, and will include the
264 #+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
265 to \\providecommand, and then place \\usepackage commands based
266 on the content of `org-latex-packages-alist'.
268 If your header, `org-latex-default-packages-alist' or
269 `org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\",
270 AUTO will automatically be replaced with a coding system derived
271 from `buffer-file-coding-system'. See also the variable
272 `org-latex-inputenc-alist' for a way to influence this mechanism.
274 Likewise, if your header contains \"\\usepackage[AUTO]{babel}\",
275 AUTO will be replaced with the language related to the language
276 code specified by `org-export-default-language', which see. Note
277 that constructions such as \"\\usepackage[french,AUTO,english]{babel}\"
280 The sectioning structure
281 ------------------------
283 The sectioning structure of the class is given by the elements
284 following the header string. For each sectioning level, a number
285 of strings is specified. A %s formatter is mandatory in each
286 section string and will be replaced by the title of the section.
288 Instead of a cons cell (numbered . unnumbered), you can also
289 provide a list of 2 or 4 elements,
291 \(numbered-open numbered-close)
295 \(numbered-open numbered-close unnumbered-open unnumbered-close)
297 providing opening and closing strings for a LaTeX environment
298 that should represent the document section. The opening clause
299 should have a %s to represent the section title.
301 Instead of a list of sectioning commands, you can also specify
302 a function name. That function will be called with two
303 parameters, the (reduced) level of the headline, and a predicate
304 non-nil when the headline should be numbered. It must return
305 a format string in which the section title will be added."

390 When this variable is non-nil, Org will use the value of a
391 headline's CUSTOM_ID property as the key for the \\label command
392 for the LaTeX section corresponding to the headline.
394 By default, Org generates its own internal section labels for all
395 headlines during LaTeX export. This process ensures that the
396 \\label keys are unique and valid, but it means the keys are not
397 available in advance of the export process.
399 Setting this variable gives you control over how Org generates
400 labels for sections during LaTeX export, so that you may know
401 their keys in advance. One reason to do this is that it allows
402 you to refer to headlines using a single label both in Org's link
403 syntax and in embedded LaTeX code.
405 For example, when this variable is non-nil, a headline like this:
411 This is section [[#sec:foo]].
413 And this is still section \\ref{sec:foo}.
416 will be exported to LaTeX as:
418 \\subsection{Some section}
420 This is section \\ref{sec:foo}.
421 And this is still section \\ref{sec:foo}.
423 Note, however, that setting this variable introduces a limitation
424 on the possible values for CUSTOM_ID. When this variable is
425 non-nil and a headline defines a CUSTOM_ID value, Org simply
426 passes this value to \\label unchanged. You are responsible for
427 ensuring that the value is a valid LaTeX \\label key, and that no
428 other \\label commands with the same key appear elsewhere in your
429 document. (Keys may contain letters, numbers, and the following
430 punctuation: '_' '.' '-' ':'.) There are no such limitations on
431 CUSTOM_ID when this variable is nil.
433 For headlines that do not define the CUSTOM_ID property, Org will
434 continue to use its default labeling scheme to generate labels
435 and resolve links into section references."

695 This package will fontify source code, possibly even with color.
696 If you want to use this, you also need to make LaTeX use the
697 listings package, and if you want to have color, the color
698 package. Just add these to `org-latex-packages-alist', for
699 example using customize, or with something like:
702 \(add-to-list 'org-latex-packages-alist '(\"\" \"listings\"))
703 \(add-to-list 'org-latex-packages-alist '(\"\" \"color\"))
707 \(setq org-latex-listings 'minted)
709 causes source code to be exported using the minted package as
710 opposed to listings. If you want to use minted, you need to add
711 the minted package to `org-latex-packages-alist', for example
712 using customize, or with
715 \(add-to-list 'org-latex-packages-alist '(\"\" \"minted\"))
717 In addition, it is necessary to install pygments
718 \(http://pygments.org), and to configure the variable
719 `org-latex-pdf-process' so that the -shell-escape option is
722 The minted choice has possible repercussions on the preview of
723 latex fragments (see `org-preview-latex-fragment'). If you run
724 into previewing problems, please consult

858 does not have a clever mechanism to detect which of these

860 does not do any error checking.
862 By default, Org uses 3 runs of `pdflatex' to do the processing.

864 the infamous egrep/locale bug:
866 http://lists.gnu.org/archive/html/bug-texinfo/2010-03/msg00031.html
868 then `texi2dvi' is the superior choice as it automates the LaTeX
869 build process by calling the \"correct\" combinations of
870 auxiliary programs. Org does offer `texi2dvi' as one of the
871 customize options. Alternatively, `rubber' and `latexmk' also
872 provide similar functionality. The latter supports `biber' out
875 Alternatively, this may be a Lisp function that does the
876 processing, so you could use this to apply the machinery of
877 AUCTeX or the Emacs LaTeX mode. This function should accept the
