Unfree software: Difference between revisions

Latest revision as of 22:25, 26 October 2024

Unfree software refers to software that has restrictive licensing on modification and/or redistribution. This type of software cannot be freely provided or distributed in an official capacity, which means that unfree software is neither built by Hydra, nor cached on the official binary cache. Despite this, Nixpkgs offers a very large collection of unfree software as derivations, however they cannot be used by default without configuring Nixpkgs and opting in to unfree software usage.

-=== For all packages ===
-This method works for NixOS system-level configuration:
-{{file|/etc/nixos/configuration.nix|nix|<nowiki>
-{
-  nixpkgs.config.allowUnfree = true;
-}
-</nowiki>}}
-=== Command Line ===
-You won't be able to install or search for an unfree package as a user unless you explicitly enable it:
-{{file|~/.config/nixpkgs/config.nix|nix|<nowiki>
-{
-  nixpkgs.config.allowUnfree = true;
-}
-</nowiki>}}
-=== Temporary allowing ===
-For temporary allowing unfree packages, you can use an environment variable:
-<syntaxhighlight lang="bash">
-$ NIXPKGS_ALLOW_UNFREE=1 nix-shell -p vscode
-</syntaxhighlight>
-Note for the new nix3-style commands, you need to pass <code>--impure</code> as well:
-<syntaxhighlight lang="bash">
-$ NIXPKGS_ALLOW_UNFREE=1 nix run --impure "nixpkgs#vscode"
-</syntaxhighlight>
