Separate `overlay.nix` and `overlay.internal.nix`, to encapsulate the `flake` argument. This allows non-flake users to import `./overlay.nix` without providing a dummy `flake = null` attr. The read-only `config.flake` option is only defined by `evalNixvim` when `lib` is extended using the overlay in Nixvim's flake outputs.

/**
|
|
Overlay function extending the Nixpkgs `lib` with Nixvim's additions.
|
|
|
|
This function is intended to be passed to `lib.extend`.
|
|
|
|
# Examples
|
|
|
|
Importing the file directly:
|
|
```
|
|
lib.extend (import (nixvim + "/lib/overlay.nix"))
|
|
```
|
|
|
|
Using the overlay from flake outputs:
|
|
```
|
|
lib.extend nixvim.lib.overlay
|
|
```
|
|
|
|
# Inputs
|
|
|
|
`lib`
|
|
: The final lib instance; the fixpoint of all extensions, including this one.
|
|
|
|
`prevLib`
|
|
: The lib instance prior to applying this overlay.
