  105. "Alist of LaTeX classes and associated header and structure.
  106. If #+LaTeX_CLASS is set in the buffer, use its value and the
  107. associated information. Here is the structure of each cell:
  108. \(class-name
  109. header-string
  110. (numbered-section . unnumbered-section\)
  111. ...\)
  112. The header string
  113. -----------------
  114. The HEADER-STRING is the header that will be inserted into the LaTeX file.
  115. It should contain the \\documentclass macro, and anything else that is needed
  116. for this setup. To this header, the following commands will be added:
  117. - Calls to \\usepackage for all packages mentioned in the variables
  118. `org-export-latex-default-packages-alist' and
  119. `org-export-latex-packages-alist'. Thus, your header definitions should
  120. avoid to also request these packages.
  121. - Lines specified via \"#+LaTeX_HEADER:\"
  122. If you need more control about the sequence in which the header is built
  123. up, or if you want to exclude one of these building blocks for a particular
  124. class, you can use the following macro-like placeholders.
  125. [DEFAULT-PACKAGES] \\usepackage statements for default packages
  126. [NO-DEFAULT-PACKAGES] do not include any of the default packages
  127. [PACKAGES] \\usepackage statements for packages
  128. [NO-PACKAGES] do not include the packages
  129. [EXTRA] the stuff from #+LaTeX_HEADER
  130. [NO-EXTRA] do not include #+LaTeX_HEADER stuff
  131. [BEAMER-HEADER-EXTRA] the beamer extra headers
  132. So a header like
  133. \\documentclass{article}
  134. [NO-DEFAULT-PACKAGES]
  135. [EXTRA]
  136. \\providecommand{\\alert}[1]{\\textbf{#1}}
  137. [PACKAGES]
  138. will omit the default packages, and will include the #+LaTeX_HEADER lines,
  139. then have a call to \\providecommand, and then place \\usepackage commands
  140. based on the content of `org-export-latex-packages-alist'.
  141. If your header or `org-export-latex-default-packages-alist' inserts
  142. \"\\usepackage[AUTO]{inputenc}\", AUTO will automatically be replaced with
  143. a coding system derived from `buffer-file-coding-system'. See also the
  144. variable `org-export-latex-inputenc-alist' for a way to influence this
  145. mechanism.
  146. The sectioning structure
  147. ------------------------
  148. The sectioning structure of the class is given by the elements following
  149. the header string. For each sectioning level, a number of strings is
  150. specified. A %s formatter is mandatory in each section string and will
  151. be replaced by the title of the section.
  152. Instead of a cons cell (numbered . unnumbered), you can also provide a list
  153. of 2 or 4 elements,
  154. (numbered-open numbered-close)
  155. or
  156. (numbered-open numbered-close unnumbered-open unnumbered-close)
  157. providing opening and closing strings for a LaTeX environment that should
  158. represent the document section. The opening clause should have a %s
  159. to represent the section title.
  160. Instead of a list of sectioning commands, you can also specify a
  161. function name. That function will be called with two parameters,
  162. the (reduced) level of the headline, and the headline text. The function
  163. must return a cons cell with the (possibly modified) headline text, and the
  164. sectioning list in the cdr."
