345 When this variable is non-nil, Org will use the value of

347 \\label commands generated.
349 By default, Org generates its own internal labels during LaTeX
350 export. This process ensures that the \\label keys are unique
351 and valid, but it means the keys are not available in advance of
354 Setting this variable gives you control over how Org generates
355 labels during LaTeX export, so that you may know their keys in
356 advance. One reason to do this is that it allows you to refer to
357 various elements using a single label both in Org's link syntax
358 and in embedded LaTeX code.
360 For example, when this variable is non-nil, a headline like this:
366 This is section [[#sec:foo]].
368 And this is still section \\ref{sec:foo}.
371 will be exported to LaTeX as:
373 \\subsection{Some section}
375 This is section \\ref{sec:foo}.
376 And this is still section \\ref{sec:foo}.
378 Note, however, that setting this variable introduces a limitation
379 on the possible values for CUSTOM_ID and NAME. When this
380 variable is non-nil, Org passes their value to \\label unchanged.
381 You are responsible for ensuring that the value is a valid LaTeX
382 \\label key, and that no other \\label commands with the same key
383 appear elsewhere in your document. (Keys may contain letters,
384 numbers, and the following punctuation: '_' '.' '-' ':'.) There
385 are no such limitations on CUSTOM_ID and NAME when this variable

427 If #+LATEX_CLASS is set in the buffer, use its value and the
428 associated information. Here is the structure of each cell:
432 (numbered-section . unnumbered-section)
438 The HEADER-STRING is the header that will be inserted into the
439 LaTeX file. It should contain the \\documentclass macro, and
440 anything else that is needed for this setup. To this header, the
441 following commands will be added:
443 - Calls to \\usepackage for all packages mentioned in the
444 variables `org-latex-default-packages-alist' and
445 `org-latex-packages-alist'. Thus, your header definitions
446 should avoid to also request these packages.
448 - Lines specified via \"#+LATEX_HEADER:\" and
449 \"#+LATEX_HEADER_EXTRA:\" keywords.
451 If you need more control about the sequence in which the header
452 is built up, or if you want to exclude one of these building
453 blocks for a particular class, you can use the following
454 macro-like placeholders.
456 [DEFAULT-PACKAGES] \\usepackage statements for default packages
457 [NO-DEFAULT-PACKAGES] do not include any of the default packages
458 [PACKAGES] \\usepackage statements for packages
459 [NO-PACKAGES] do not include the packages
460 [EXTRA] the stuff from #+LATEX_HEADER(_EXTRA)
461 [NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff
465 \\documentclass{article}
466 [NO-DEFAULT-PACKAGES]
468 \\providecommand{\\alert}[1]{\\textbf{#1}}
471 will omit the default packages, and will include the
472 #+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
473 to \\providecommand, and then place \\usepackage commands based
474 on the content of `org-latex-packages-alist'.
476 If your header, `org-latex-default-packages-alist' or
477 `org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\",
478 AUTO will automatically be replaced with a coding system derived
479 from `buffer-file-coding-system'. See also the variable
480 `org-latex-inputenc-alist' for a way to influence this mechanism.
482 Likewise, if your header contains \"\\usepackage[AUTO]{babel}\"
483 or \"\\usepackage[AUTO]{polyglossia}\", AUTO will be replaced
484 with the language related to the language code specified by
485 `org-export-default-language'. Note that constructions such as
486 \"\\usepackage[french,AUTO,english]{babel}\" are permitted. For
487 Polyglossia the language will be set via the macros
488 \"\\setmainlanguage\" and \"\\setotherlanguage\". See also
489 `org-latex-guess-babel-language' and
490 `org-latex-guess-polyglossia-language'.
492 The sectioning structure
493 ------------------------
495 The sectioning structure of the class is given by the elements
496 following the header string. For each sectioning level, a number
497 of strings is specified. A %s formatter is mandatory in each
498 section string and will be replaced by the title of the section.
500 Instead of a cons cell (numbered . unnumbered), you can also
501 provide a list of 2 or 4 elements,
503 (numbered-open numbered-close)
507 (numbered-open numbered-close unnumbered-open unnumbered-close)
509 providing opening and closing strings for a LaTeX environment
510 that should represent the document section. The opening clause
511 should have a %s to represent the section title.
513 Instead of a list of sectioning commands, you can also specify
514 a function name. That function will be called with two
515 parameters, the (reduced) level of the headline, and a predicate
516 non-nil when the headline should be numbered. It must return
517 a format string in which the section title will be added."
