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