38 | # pod2latex, version 1.1 |
| 39 | # by Taro Kawagish (kawagish@imslab.co.jp), Jan 11, 1995. |
| 40 | # |
| 41 | # pod2latex filters Perl pod documents to LaTeX documents. |
| 42 | # |
| 43 | # What pod2latex does: |
| 44 | # 1. Pod file 'perl_doc_entry.pod' is filtered to 'perl_doc_entry.tex'. |
| 45 | # 2. Indented paragraphs are translated into |
| 46 | # '\begin{verbatim} ... \end{verbatim}'. |
| 47 | # 3. '=head1 heading' command is translated into '\section{heading}' |
| 48 | # 4. '=head2 heading' command is translated into '\subsection*{heading}' |
| 49 | # 5. '=over N' command is translated into |
| 50 | # '\begin{itemize}' if following =item starts with *, |
| 51 | # '\begin{enumerate}' if following =item starts with 1., |
| 52 | # '\begin{description}' if else. |
| 53 | # (indentation level N is ignored.) |
| 54 | # 6. '=item * heading' command is translated into '\item heading', |
| 55 | # '=item 1. heading' command is translated into '\item heading', |
| 56 | # '=item heading' command(other) is translated into '\item[heading]'. |
| 57 | # 7. '=back' command is translated into |
| 58 | # '\end{itemize}' if started with '\begin{itemize}', |
| 59 | # '\end{enumerate}' if started with '\begin{enumerate}', |
| 60 | # '\end{description}' if started with '\begin{description}'. |
| 61 | # 8. other paragraphs are translated into strings with TeX special characters |
| 62 | # escaped. |
| 63 | # 9. In heading text, and other paragraphs, the following translation of pod |
| 64 | # quotes are done, and then TeX special characters are escaped after that. |
| 65 | # I<text> to {\em text\/}, |
| 66 | # B<text> to {\bf text}, |
| 67 | # S<text> to text1, |
| 68 | # where text1 is a string with blank characters replaced with ~, |
| 69 | # C<text> to {\tt text2}, |
| 70 | # where text2 is a string with TeX special characters escaped to |
| 71 | # obtain a literal printout, |
| 72 | # E<text> (HTML escape) to TeX escaped string, |
| 73 | # L<text> to referencing string as is done by pod2man, |
| 74 | # F<file> to {\em file\/}, |
| 75 | # Z<> to a null string, |
| 76 | # 10. those headings are indexed: |
| 77 | # '=head1 heading' => \section{heading}\index{heading} |
| 78 | # '=head2 heading' => \subsection*{heading}\index{heading} |
| 79 | # only when heading does not match frequent patterns such as |
| 80 | # DESCRIPTION, DIAGNOSTICS,... |
| 81 | # '=item heading' => \item{heading}\index{heading} |
| 82 | # |
| 83 | # Usage: |
| 84 | # pod2latex perl_doc_entry.pod |
| 85 | # this will write to a file 'perl_doc_entry.tex'. |
| 86 | # |
| 87 | # To LaTeX: |
| 88 | # The following commands need to be defined in the preamble of the LaTeX |
| 89 | # document: |
| 90 | # \def\C++{{\rm C\kern-.05em\raise.3ex\hbox{\footnotesize ++}}} |
| 91 | # \def\underscore{\leavevmode\kern.04em\vbox{\hrule width 0.4em height 0.3pt}} |
| 92 | # and \parindent should be set zero: |
| 93 | # \setlength{\parindent}{0pt} |
| 94 | # |
| 95 | # Note: |
| 96 | # This script was written modifing pod2man. |
| 97 | # |
| 98 | # Bug: |
| 99 | # If HTML escapes E<text> other than E<amp>,E<lt>,E<gt>,E<quot> are used |
| 100 | # in C<>, translation will produce wrong character strings. |
| 101 | # Translation of HTML escapes of various European accents might be wrong. |
