Moved `extraFiles` from `modules/output.nix` into its own file `modules/files.nix`.
Users should now assign text to a `text` attribute, however they could
also assign a file path to a `source` attribute instead.
The old method of directly assigning a string still works, and is
coerced to the new type along with a deprecation warning.
To enable some features (like adding tree-sitter queries) we need to add
files to specific directories in the runtime path (queries/lang/file.scm
for tree-sitter queries for example).
This commit adds support for specifying such files. You must be careful
to not have any collisions between `files` and `extraFiles`.
The lua dependency is required to perform transforms (luasnip can
fallback to a simpler algorithm if it's absent). This requires us to
expose the `extraLuaPackages` option of makeNeovimConfig.
This represents a major rearchitecture for nixvim, so I'm leaving this up to track the progress for now, and to serve as a reference for any breaking changes during transition.
The main change is, of course, being able to use nixvim standalone. To do this, you should use the new build function, which takes in two arguments: the system architecture (e.g. x86_64-linux) and the configuration. For the new configuration, do not use the programs.nixvim. prefix.
For module development, the main change is that you should no longer prefix your modules with programs.nixvim..
