Generate libwebp Container Spec Docs from Text Source
=====================================================
HTML generation requires kramdown [1], easily installed as a
rubygem [2]. Rubygems installation should satisfy dependencies
automatically.
[1]: http://kramdown.rubyforge.org/
[2]: http://rubygems.org/
HTML generation can then be done from the project root:
$ kramdown doc/webp-container-spec.txt --template doc/template.html > \
doc/output/webp-container-spec.html
kramdown can optionally syntax highlight code blocks, using CodeRay [3],
a dependency of kramdown that rubygems will install automatically. The
following will apply inline CSS styling, and then use perl to strip
line numbers and unwanted leading whitespace.
$ kramdown doc/webp-lossless-bitstream-spec.txt --template \
doc/template.html --coderay-css style | \
perl -p -e 's|<span class="no">.*?</span>\s||gm' > \
doc/output/webp-lossless-bitstream-spec.html
Note that code blocks must be immediately followed by a language
identifier for syntax highlighting to succeed. Example:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
int block_index = (y >> size_bits) * block_xsize +
(x >> size_bits);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
{:lang='c'}
