By default, Org generates its own internal labels during LaTeX export. This process ensures that the \\label keys are unique and valid, but it means the keys are not available in advance of the export process. Setting this variable gives you control over how Org generates labels during LaTeX export, so that you may know their keys in advance. One reason to do this is that it allows you to refer to various elements using a single label both in Org's link syntax and in embedded LaTeX code. For example, when this variable is non-nil, a headline like this: ** Some section :PROPERTIES: :CUSTOM_ID: sec:foo :END: This is section [[#sec:foo]]. #+BEGIN_EXPORT latex And this is still section \\ref{sec:foo}. #+END_EXPORT will be exported to LaTeX as: \\subsection{Some section} \\label{sec:foo} This is section \\ref{sec:foo}. And this is still section \\ref{sec:foo}. A non-default value of `org-latex-reference-command' will change the command (\\ref by default) used to create label references. Note, however, that setting this variable introduces a limitation on the possible values for CUSTOM_ID and NAME. When this variable is non-nil, Org passes their value to \\label unchanged. You are responsible for ensuring that the value is a valid LaTeX \\label key, and that no other \\label commands with the same key appear elsewhere in your document. (Keys may contain letters, numbers, and the following punctuation: `_' `.' `-' `:'.) There are no such limitations on CUSTOM_ID and NAME when this variable is nil.

To this header, the following commands will be added: - Calls to \\usepackage for all packages mentioned in the variables `org-latex-default-packages-alist' and `org-latex-packages-alist'. Thus, your header definitions should avoid to also request these packages. - Lines specified via \"#+LATEX_HEADER:\" and \"#+LATEX_HEADER_EXTRA:\" keywords. If you need more control about the sequence in which the header is built up, or if you want to exclude one of these building blocks for a particular class, you can use the following macro-like placeholders. [DEFAULT-PACKAGES] \\usepackage statements for default packages [NO-DEFAULT-PACKAGES] do not include any of the default packages [PACKAGES] \\usepackage statements for packages [NO-PACKAGES] do not include the packages [EXTRA] the stuff from #+LATEX_HEADER(_EXTRA) [NO-EXTRA] do not include #+LATEX_HEADER(_EXTRA) stuff So a header like \\documentclass{article} [NO-DEFAULT-PACKAGES] [EXTRA] \\providecommand{\\alert}[1]{\\textbf{#1}} [PACKAGES] will omit the default packages, and will include the #+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call to \\providecommand, and then place \\usepackage commands based on the content of `org-latex-packages-alist'. If your header, `org-latex-default-packages-alist' or `org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\", AUTO will automatically be replaced with a coding system derived from `buffer-file-coding-system'. See also the variable `org-latex-inputenc-alist' for a way to influence this mechanism. Likewise, if your header contains \"\\usepackage[AUTO]{babel}\" or \"\\usepackage[AUTO]{polyglossia}\", AUTO will be replaced with the language related to the language code specified by `org-export-default-language'. Note that constructions such as \"\\usepackage[french,AUTO,english]{babel}\" are permitted. For Polyglossia the language will be set via the macros \"\\setmainlanguage\" and \"\\setotherlanguage\". See also `org-latex-guess-babel-language' and `org-latex-guess-polyglossia-language'. The sectioning structure ------------------------ The sectioning structure of the class is given by the elements following the header string. For each sectioning level, a number of strings is specified. A %s formatter is mandatory in each section string and will be replaced by the title of the section. Instead of a cons cell (numbered . unnumbered), you can also provide a list of 2 or 4 elements, (numbered-open numbered-close) or (numbered-open numbered-close unnumbered-open unnumbered-close) providing opening and closing strings for a LaTeX environment that should represent the document section. The opening clause should have a %s to represent the section title. Instead of a list of sectioning commands, you can also specify a function name. That function will be called with two parameters, the (reduced) level of the headline, and a predicate non-nil when the headline should be numbered. It must return a format string in which the section title will be added." :group 'org-export-latex :type '(repeat (list (string :tag "LaTeX class") (string :tag "LaTeX header") (repeat :tag "Levels" :inline t (choice (cons :tag "Heading" (string :tag " numbered") (string :tag "unnumbered")) (list :tag "Environment" (string :tag "Opening (numbered)") (string :tag "Closing (numbered)") (string :tag "Opening (unnumbered)") (string :tag "Closing (unnumbered)")) (function :tag "Hook computing sectioning")))))) (defcustom org-latex-inputenc-alist nil "Alist of inputenc coding system names, and what should really be used.
