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
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
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
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
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
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)
