In the two places where our "helpers" lib is exclusively internal
(flake module args and building the docs), we no longer supply `pkgs`.
In the other 4 locations, we now note why we still do in a comment.
The old `default.nix` is inlined into the "lib" flake-module, which is
the only place it was used.
This allows "helpers" to take its rightful place at the root of `./lib` 👑
Since cbd1003d9d I'm able to add _some_
invalid config definitions to modules the tests are using and get no
build error.
For example `extraConfigLua = null;` should produce an invalid type
error, but doesn't.
One less visible change in that commit is the move away from using the
"standalone" wrapper (`makeNixvimWithModule`), which implicitly sets
`wrapRc = true`.
Adding back `wrapRc` to the tests seems to fix the issue, however this
makes me wonder if there's an underlying issue with wrapping/not-wrapping?
Perhaps we've simply uncovered a long-standing eval issue that is masked
over by using `wrapRc`?
Warnings and assertions defined as `config.warnings` and `config.assertions`
respectively will be checked as part of the test derivation, instead of
when evaluating the modules.
Adds new `checkWarnings` and `checkAssertions` test options (default true).
