This is a packaging of Inform with Nix. The version available in nixpkgs predates the open-sourcing of Inform, so it necessarily downloads binaries and packages them. This packaging builds Inform from source. I would like to upstream this to nixpkgs, but I don't have the time to get the GUI derivation working. I am publishing my efforts in the interest of someone helping upstream this.
Try it out with:
nix run github:zombiezen/inform-nix -- -helpThe flake is released as MIT, same as nixpkgs. Inform itself is released under the Artistic License 2.0.
