Not all headers are public, or contain public types. GTK-Doc allows
adding headers to be ignored during the "scan" phase, by passing the
`--ignore-headers` command line argument to gtkdoc-scan.
Currently, you can do something like:
ignored_headers = [ 'foo-private.h', 'bar-private.h', ]
gnome.gtkdoc(...
scan_args: [
'--ignore-headers=' + ' '.join(ignored_headers),
],
...)
But it does not guarantee escaping rules and it's definitely not nice.
We can add a simpler version of that mechanism through a new positional
argument, `ignore_headers`, which behaves like `content_files` or
`html_assets`, and takes an array of header files to ignore:
gnome.gtkdoc(...
ignore_headers: ignored_headers,
...)
If a `<modulename>-overrides.txt` file exists in the docs directory it
means it's intended to be used in place of the one gtk-doc generates.
GLib and GTK+, for instance, ship with one because some of the types
they provide — like the thread primitives, or the platform macros —
contain architecture-dependent fields that should not be accessed
directly.
This commit should close the last bit of issue #550.
Allowing the object tree to be generated.
We need to add options to allow copying the ncesseary sources and
assets so the HTML generator can work with them (everything is
relative so we need to copy them in the build directory).
Until now the documentation was not generated from the user provided
main sgml file but it was using a generated one, which lead to a broken
documentation. Starting using it revealed the other bugs fixed in that
commit.
The extra arguments are typically used to specified the location of
installed API references that gtk-doc can use to create cross links
for symbols.
