   4 ### texi2html customization script for LilyPond
   5 ### Author: Reinhold Kainhofer <reinhold@kainhofer.com>, 2008.
   6 ###         Some code parts copied from texi2html and adapted. These functions
   7 ###         were written mainly by Patrice Dumas
   8 ### License: GPLv3+
   9 ###
  10 ###
  11 ### Features implemented here:
  12 ### -) For split manuals, the main page is index.html.
  13 ### -) All @unnumbered* sections are placed into the same file
  14 ###    (implemented by split_at_numbered_sections)
  15 ### -) Use our custom CSS file, with IE-specific fixes in another CSS file,
  16 ###    impelmented by lilypond_css_lines
  17 ### -) TOC (folded, with the current page highlighted) in an overflown <div>
  18 ###    is added to every page; implemented by:
  19 ###           lilypond_print_element_header -- building of the TOC
  20 ###           lilypond_toc_body -- generation of customized TOC output
  21 ###           lilypond_print_page_head -- start <div id="main">
  22 ###           print_lilypond_page_foot -- closing id=main, output of footer & TOC
  23 ### -) External refs are formatted only as "Text of the node" (not as >>see
  24 ###    "NODE" section "SECTION" in "BOOK"<< like with default texi2html). Also,
  25 ###    the leading "(book-name)" is removed.
  26 ###    Implemented by overriding lilypond_external_ref
  27 ### -) Navigation bars on top/bottom of the page and between sections are not
  28 ###    left-aligned, but use a combination of left/center/right aligned table
  29 ###    cells; For this, I heavily extend the texi2html code to allow for
  30 ###    differently aligned cells and for multi-line tables);
  31 ###    Implemented in lilypond_print_navigation
  32 ### -) Different formatting than the default: example uses the same formatting
  33 ###    as quote.
  34 ### -) Allow translated section titles: All section titles can be translated,
  35 ###    the original (English) title is associated with @translationof. This is
  36 ###    needed, because the file name / anchor is generated from the original
  37 ###    English title, since otherwise language-autoselection would break with
  38 ###    posted links.
  39 ###    Since it is then no longer possible to obtain the file name from the
  40 ###    section title, I keep a sectionname<=>filename/anchor around. This way,
  41 ###    xrefs from other manuals can simply load that map and retrieve the
  42 ###    correct file name for the link. Implemented in:
  43 ###           lilypond_unknown (handling of @translationof, in case
  44 ###                             extract_texi_filenames.py messes up...)
  45 ###           lilypond_element_file_name (correct file name: use the map)
  46 ###           lilypond_element_target_name (correct anchor: use the map)
  47 ###           lilypond_init_map (read in the externally created map from disk)
  48 ###           lilypond_external_href (load the map for xrefs, use the correct
  49 ###                                   link target)
  50 ### -) The HTML anchors for all sections are derived from the node name /
  51 ###    section title (pre-generated in the .xref-map file). Implemented by:
  52 ###           lilypond_element_target_name (adjust section anchors)
  53 ### -) Use the standard footnote format "<sup>nr</sup> text" instead of the
  54 ###    ugly format of texi2html (<h3>(nr)</h3><p>text</p>). Implemented in
  55 ###           makeinfo_like_foot_line_and_ref
  56 ###           makeinfo_like_foot_lines
  57 ###           makeinfo_like_paragraph
  58 ###
  59 ###
  60 ### Useful helper functions:
  61 ### -) texinfo_file_name($node_name): returns a texinfo-compatible file name
  62 ###    for the given string $node_name (whitespace trimmed/replaced by -,
  63 ###    non-standard chars replaced by _xxxx (ascii char code) and forced to
  64 ###    start with a letter by prepending t_g if necessary)
