Zig Language Support plugin

This a plugin for KDevelop that adds language support for Zig. It uses zig's builtin parser via a library.

Syntax error messages
Syntax highlighting of structs, fns, enums. Rainbow colored local vars
Goto decl, view doc comments on hover.
Highlight usages on hover, lookup uses of fns, vars, etc..
Resolve imports from zig std lib and user defined packages
Evalutate some comptime expressions (enum switches, if exprs, basic math exprs)
Basic typed fn resolution for fns that return structs or typed params (still WIP)
Hints for type mismatches, missing args, invalid enum/struct fields, etc..

Resolving basic math expressions

The following shows it is able to resolve methods of a USBCDC driver using zig's builtin buffered writer to print.

First, build and install kdevelop from source so the test libraries are availble.

mkdir build
cd build
cmake -G ninja ..
ninja install

Use zig test duchain/kdevzigastparser.zig to run zig tests. Run the duchaintest for kdev-zig tests.

In case you run into problems with it use ninja uninstall.

To enable debug logging set the following env var.

export QT_LOGGING_RULES="kdevelop.languages.zig.duchain.debug=true;"

Then run KDevelop.

You must have zig 0.12 dev installed somewhere where FindZig.cmake will find it (eg ".local/bin").

It was forked from kdev-rust and borrows code from kdev-python so licensed under the GPL.
