I think that's a misreading - would interpret RJVB's "it should also provide a 
fully functional parser" as an acknowledgement that the Meson plugin should 
already provide enough information for kdev-clang to parse projects correctly.

But anyway...

For basic highlighting, there's some information on the ksyntaxhighlighting 
XML format here:
https://docs.kde.org/stable5/en/applications/katepart/highlight.html

This already seems to exist for Meson, see Tools -> Highlighting -> Other -> 
Meson, the source file is:
https://cgit.kde.org/syntax-highlighting.git/tree/data/syntax/meson.xml

If you want a fancy semantic-analysis parser using the DUChain, the generated 
docs are here (note the inconspicuous <Overview | Design | Implementing | 
Using> tabs):
https://api.kde.org/extragear-api/kdevelop-apidocs/kdevelop/kdevplatform/
language/duchain/html/duchain-design.html
