Akku

About two hundred R6RS & R7RS libraries from Akku (which also mirrors snow-fort) are available inside the akkuPackages attrset, and the Akku executable itself is at the top level as akku. The packages could be used in a derivation's buildInputs, work inside of nix-shell, and are tested using Chez & Chibi Scheme during build time.

Including a package as a build input is done in the typical Nix fashion. For example, to include a bunch of SRFIs primarily for Chez Scheme in a derivation, one might write:

{
  buildInputs = [
    chez
    akkuPackages.chez-srfi
  ];
}

The package index is located in pkgs/tools/package-management/akku as deps.toml, and should be updated occasionally by running ./update.sh in the directory. Doing so will pull the source URLs for new packages and more recent versions, then write them to the TOML.
