Basically it just wraps together `nix shell -c` and `nix-index`. You stick a `,` in front of a command to
|
||||
run it from whatever location it happens to occupy in `nixpkgs` without really thinking about it.
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
nix-env -i -f .
|
||||
```
|
||||
- Nix with [Flakes](https://nixos.wiki/wiki/Flakes):
|
||||
|
||||
```bash
|
||||
$ nix profile install github:nix-community/comma
|
||||
```
|
||||
|
||||
- No flakes:
|
||||
|
||||
```bash
|
||||
$ nix-env -i -f "https://github.com/nix-community/comma/archive/master.tar.gz"
|
||||
```
|
||||
|
||||
