;;; Commentary:

|
||
;; This library implements a LaTeX back-end for Org generic exporter.
|
||
;;
|
||
;; To test it, run
|
||
;;
|
||
;; M-: (org-export-to-buffer 'e-latex "*Test e-LaTeX*") RET
|
||
;;
|
||
;; in an org-mode buffer then switch to the buffer to see the LaTeX
|
||
;; export. See contrib/lisp/org-export.el for more details on how
|
||
;; this exporter works.
|
||
;;
|
||
;; It introduces three new buffer keywords: "LATEX_CLASS",
|
||
;; "LATEX_CLASS_OPTIONS" and "LATEX_HEADER".

"Alist of LaTeX classes and associated header and structure.
|
||
If #+LaTeX_CLASS is set in the buffer, use its value and the
|
||
associated information. Here is the structure of each cell:
|
||
|
||
\(class-name
|
||
header-string
|
||
\(numbered-section . unnumbered-section\)
|
||
...\)
|
||
|
||
The header string
|
||
-----------------
|
||
|
||
The HEADER-STRING is the header that will be inserted into the
|
||
LaTeX file. It should contain the \\documentclass macro, and
|
||
anything else that is needed for this setup. To this header, the
|
||
following commands will be added:
|
||
|
||
- Calls to \\usepackage for all packages mentioned in the
|
||
variables `org-export-latex-default-packages-alist' and
|
||
`org-export-latex-packages-alist'. Thus, your header
|
||
definitions should avoid to also request these packages.
|
||
|
||
- Lines specified via \"#+LaTeX_HEADER:\"
|
||
|
||
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
|
||
[NO-EXTRA] do not include #+LaTeX_HEADER 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 lines, then have a call to \\providecommand, and
|
||
then place \\usepackage commands based on the content of
|
||
`org-export-latex-packages-alist'.
|
||
|
||
If your header, `org-export-latex-default-packages-alist' or
|
||
`org-export-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-e-latex-inputenc-alist' for a way to influence this
|
||
mechanism.
|
||
|
||
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."
