gtk-doc assumes Docbook4, with <ulink> and so on.
Without this, all the links in markdown are converted
to <link xlink:href=...> and then lost in the docbook->html
conversion.
pandoc insists on using the xlink namespace for hrefs,
and the namespace setup doesn't carry over xi:includes.
My first fix was to tell pandoc to generate standalone
docbook documents, which makes it insert the xlink
namespace. But it also makes it wrap all sections and
chapters in articles, and that messes up our toc structure.
So, patch things up differently by stripping the xlink:
from hrefs via regex.
Yay for XML!
This flag causes pandoc to emit a proper doctype
declaration and, crucially, namespace declarations
for the xlink namespace that it insists on using
for href attributes. Without this, putting external
links in md documents doesn't survive the journey
through xml.
Arrange for files named section-foo.md to be turned
into docbook sections, while others get turned into
chapters. This is necessary to allow including such
content in chapters, since chapters in docbook don't
nest.
Use pandoc to convert freestanding markdown files to docbook for
inclusion in the generated docs, and use bits and pieces of
gtk-doc code to continue expanding typical gtk-doc abbreviations.
The new tool for markdown -> docbook is a python script called
gtk-markdown-to-docbook.
The markdown dialect is specified via a list of pandoc extension
in gtk-markdown-to-docbook. It includes header annocations,
definition lists and tables, among other things.
This commit converts the 3 overview chapters (drawing, input
handling and actions) and the migration guide to markdown
syntax. Other files that are still listed in content_files
can be converted later.
This commit adds a pandoc dependency.
