# nix-exprs
## how to use
### enable cachix
i have a binary cache at <https://getchoo.cachix.org>, make sure to enable it
in your flake or nixos/darwin config.
### library
> **Note**
> coming soon
### flake configuration
```nix
{
inputs = {
getchoo = {
url = "github:getchoo/overlay";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = {
nixpkgs,
getchoo,
...
}: {
nixosConfigurations.hostname = nixpkgs.lib.nixosSystem {
modules = [
{
nixpkgs.overlays = [getchoo.overlays.default];
environment.systemPackages = with pkgs; [
treefetch
];
}
];
};
};
}
```
### nix channels
#### adding the channel
```bash
nix-channel --add https://github.com/getchoo/nix-exprs/archive/main.tar.gz getchoo
nix-channel --update
```
#### usage
```nix
{pkgs, ...}: let
getchoo = import <getchoo>;
in {
nixpkgs.overlays = [getchoo.overlays.default];
environment.systemPackages = with pkgs; [
treefetch
];
}
```
### cli support
`nixpkgs.overlays` does not configure overlays for tools
such as `nix(-)run`, `nix(-)shell`, etc.
the best way to make this overlay available to them is to
add it to your flake registry or `~/.config/nixpkgs/overlays.nix`.
#### flake registry
```shell
nix registry add getchoo github:getchoo/overlay
nix run getchoo#treefetch
```
#### overlays.nix
[add the channel](#adding-the-channel) to your nix profile, then place
this in `~/.config/nixpkgs/overlays.nix` (or a nix file in `~/.config/nixpkgs/overlays/`):
```nix
let
getchoo = import <getchoo>;
in [getchoo.overlays.default]
```
