  321. \\label commands generated.
  322. By default, Org generates its own internal labels during LaTeX
  323. export. This process ensures that the \\label keys are unique
  324. and valid, but it means the keys are not available in advance of
  325. the export process.
  326. Setting this variable gives you control over how Org generates
  327. labels during LaTeX export, so that you may know their keys in
  328. advance. One reason to do this is that it allows you to refer to
  329. various elements using a single label both in Org's link syntax
  330. and in embedded LaTeX code.
  331. For example, when this variable is non-nil, a headline like this:
  332. ** Some section
  333. :PROPERTIES:
  334. :CUSTOM_ID: sec:foo
  335. :END:
  336. This is section [[#sec:foo]].
  337. #+BEGIN_EXPORT latex
  338. And this is still section \\ref{sec:foo}.
  339. #+END_EXPORT
  340. will be exported to LaTeX as:
  341. \\subsection{Some section}
  342. \\label{sec:foo}
  343. This is section \\ref{sec:foo}.
  344. And this is still section \\ref{sec:foo}.
  345. Note, however, that setting this variable introduces a limitation
  346. on the possible values for CUSTOM_ID and NAME. When this
  347. variable is non-nil, Org passes their value to \\label unchanged.
  348. You are responsible for ensuring that the value is a valid LaTeX
  349. \\label key, and that no other \\label commands with the same key
  350. appear elsewhere in your document. (Keys may contain letters,
  351. numbers, and the following punctuation: '_' '.' '-' ':'.) There
  352. are no such limitations on CUSTOM_ID and NAME when this variable
  353. is nil.
  354. For headlines that do not define the CUSTOM_ID property or

  390. If #+LATEX_CLASS is set in the buffer, use its value and the

  392. (class-name
  393. header-string
  394. (numbered-section . unnumbered-section)
  395. ...)
  396. The header string
  397. -----------------
  398. The HEADER-STRING is the header that will be inserted into the
  399. LaTeX file. It should contain the \\documentclass macro, and
  400. anything else that is needed for this setup. To this header, the
  401. following commands will be added:
  402. - Calls to \\usepackage for all packages mentioned in the
  403. variables `org-latex-default-packages-alist' and
  404. `org-latex-packages-alist'. Thus, your header definitions
  405. should avoid to also request these packages.
  406. - Lines specified via \"#+LATEX_HEADER:\" and
  407. \"#+LATEX_HEADER_EXTRA:\" keywords.
  408. If you need more control about the sequence in which the header
  409. is built up, or if you want to exclude one of these building
  410. blocks for a particular class, you can use the following
  411. macro-like placeholders.
  412. [DEFAULT-PACKAGES] \\usepackage statements for default packages
  413. [NO-DEFAULT-PACKAGES] do not include any of the default packages
  414. [PACKAGES] \\usepackage statements for packages
  415. [NO-PACKAGES] do not include the packages
  416. [EXTRA] the stuff from #+LATEX_HEADER(_EXTRA)
  417. [NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff
  418. So a header like
  419. \\documentclass{article}
  420. [NO-DEFAULT-PACKAGES]
  421. [EXTRA]
  422. \\providecommand{\\alert}[1]{\\textbf{#1}}
  423. [PACKAGES]
  424. will omit the default packages, and will include the
  425. #+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
  426. to \\providecommand, and then place \\usepackage commands based
  427. on the content of `org-latex-packages-alist'.
  428. If your header, `org-latex-default-packages-alist' or
  429. `org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\",
  430. AUTO will automatically be replaced with a coding system derived
  431. from `buffer-file-coding-system'. See also the variable
  432. `org-latex-inputenc-alist' for a way to influence this mechanism.
  433. Likewise, if your header contains \"\\usepackage[AUTO]{babel}\"
  434. or \"\\usepackage[AUTO]{polyglossia}\", AUTO will be replaced
  435. with the language related to the language code specified by
  436. `org-export-default-language'. Note that constructions such as
  437. \"\\usepackage[french,AUTO,english]{babel}\" are permitted. For
  438. Polyglossia the language will be set via the macros
  439. \"\\setmainlanguage\" and \"\\setotherlanguage\". See also
  440. `org-latex-guess-babel-language' and
  441. `org-latex-guess-polyglossia-language'.
  442. The sectioning structure
  443. ------------------------
  444. The sectioning structure of the class is given by the elements
  445. following the header string. For each sectioning level, a number
  446. of strings is specified. A %s formatter is mandatory in each
  447. section string and will be replaced by the title of the section.
  448. Instead of a cons cell (numbered . unnumbered), you can also
  449. provide a list of 2 or 4 elements,
  450. (numbered-open numbered-close)
  451. or
  452. (numbered-open numbered-close unnumbered-open unnumbered-close)
  453. providing opening and closing strings for a LaTeX environment
  454. that should represent the document section. The opening clause
  455. should have a %s to represent the section title.
  456. Instead of a list of sectioning commands, you can also specify
  457. a function name. That function will be called with two
  458. parameters, the (reduced) level of the headline, and a predicate
  459. non-nil when the headline should be numbered. It must return
  460. a format string in which the section title will be added."
