Previously, `lib/top-level.nix` used an `_isExtended` flag to indicate
whether the provided `lib` was already extended. This made bootstrapping
unclear and introduced the possibility of circular construction.
All construction now flows through the lib-overlay, removing
`_isExtended`. As a result, `lib/top-level.nix` always receives the
final extended lib.
The `<flake>.lib.nixvim` output is now defined as:
(lib.extend <nixvim>.lib.overlay).nixvim
The overlay now imports `top-level.nix` directly, making it the
canonical entrypoint for constructing Nixvim's section of the lib.
A clarifying doccomment was added to `lib/top-level.nix`.

/**
|
|
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 ./overlay.nix { flake = nixvim; })
|
|
```
|
|
|
|
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.
