Environment variables

This page lists environment variables referenced by the Nix configuration.

Build-time variables

• FRANKLYN_USE_FAKE_MVN_HASH
  • Used in server/default.nix
  • If set (non-empty), the Maven derivation uses pkgs.lib.fakeHash to avoid pinning the real hash.
  • After changing server/pom.xml, run scripts/update-mvn-hash.sh to write the new hash for your OS (Linux or macOS) into server/default.nix. The script finds the hash lines by their # linux / # darwin comments, so keep those comments in place.

Dev-shell variables

• LIBCLANG_PATH

  • Exported in the Sentinel dev shell (sentinel/default.nix) for Rust tooling that needs libclang.

• HUGO_GITHUB_PROJECT_URL

  • Exported in the Hugo dev shell (hugo/default.nix).
