Every now and then I've pondered on this a bit. There are parsers out
there, of course; we could consider using something like tree-sitter.
There's just two little problems:
- That's a massive dependency to drag into the docs build that seems
unlikely to speed things up.
- kernel-doc is really two parsers - one for C code, one for the
comment syntax. Strangely, nobody has written a grammar for this
combination.
A suitably motivated developer could probably create a C+kerneldoc
grammer that would let us make a rock-solid, tree-sitter-based parser
that would be mostly maintained by somebody else. But that doesn't get
us around the "adding a big dependency" problem.
