# comma

Comma runs software without installing it.

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

- 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"
  ```

## NixOS installation

- No flakes:

  replace "v1.2.0" with the latest version

  ```nix
  environment.systemPackages =
  let
    comma = (import (pkgs.fetchFromGitHub {
      owner = "nix-community";
      repo = "comma";
      rev = "v1.2.0";
      sha256 = "0000000000000000000000000000000000000000000000000000";
    })).default;
  in [ comma ];
  ```


- Flakes

  Add

  ```nix
  inputs.comma = {
    url = "github:nix-community/comma";
  };
  ```

  to inputs

  and

  `inputs.comma.overlays.default` (or comma without `inputs.` if you use explicit input arguments)

  to nixpkgs.overlays


## Usage
