- `neovimRcContent`: Extra vimL code sourced by the generated `init.lua`.
- `wrapperArgs`: Extra arguments forwarded to the `makeWrapper` call.
- `wrapRc`: Nix, not being able to write in your `$HOME`, loads the
generated Neovim configuration via its `-u` argument, i.e. : `-u /nix/store/...generatedInit.lua`. This has side effects like preventing Neovim from reading your config in `$XDG_CONFIG_HOME` (see bullet 7 of [`:help startup`](https://neovim.io/doc/user/starting.html#_initialization) in Neovim). Disable it if you want to generate your own wrapper. You can still reuse while reusing the logic of the nixpkgs wrapper and access the generated config via `neovim.passthru.initRc`.
