## Nix writers
|
|
|
|
- Jednoduchý způsob přidávání skriptů v různých programovacích jazycích do systému
|
|
- [https://nixos.wiki/wiki/Nix-writers](https://nixos.wiki/wiki/Nix-writers) - pro všechny podporované jazyky
|
|
- Rozdíl oproti klasickému `pkgs.writeShellScriptBin`
|
|
- [nixpkgs](https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/writers/scripts.nix) - pro všechny možnosti konfigurace skriptů
