-- Zig plugin for lint+

--- CONFIG ---

-- config.lint.zig_mode: "ast-check" | "build"
--   changes the linting mode. ast-check is a quick'n'dirty check (default),
--   build compiles the tests in a file (but does not run them).
-- config.lint.zig_args: table[string]
--   passes the given table of arguments to zig test. this does not have any
--   effect in "ast-check" mode.

--- IMPLEMENTATION ---
