prassoai/homebrew-tap

Public distribution channel for the murmur CLI — the command-line client for the Murmur agent orchestration platform. The same prebuilt release binaries are served two ways: a Homebrew formula and a Nix flake. You do not need access to the (private) murmuration source repo to install from here.

Homebrew

brew install prassoai/tap/murmur
murmur version --client

Nix (flakes)

The flake lives in this public repo, so it installs with zero private-repo access:

# One-off run:
nix run github:prassoai/homebrew-tap#murmur -- version --client

# Install into your profile:
nix profile install github:prassoai/homebrew-tap#murmur

The CLI is proprietary, so the package is marked unfree; opt in when invoking:

export NIXPKGS_ALLOW_UNFREE=1
nix run --impure github:prassoai/homebrew-tap#murmur -- version --client

Supported systems: x86_64-linux, aarch64-linux, x86_64-darwin, aarch64-darwin. The binaries are statically linked (CGO_ENABLED=0); the flake also runs autoPatchelfHook on Linux so older dynamically-linked assets still launch on a bare NixOS host.

How it stays current

Both surfaces are generated automatically. When a stable murmur release is cut, prassoai/murmuration's release workflow sends a single update-formula repository_dispatch carrying the release tag and per-platform sha256. .github/workflows/update-formula.yaml renders both Formula/murmur.rb and nix/release.lock.json from that one payload and commits them together, so Homebrew and Nix always point at the same release. Don't edit Formula/*.rb or nix/release.lock.json by hand — they are overwritten on the next release.

The design rationale lives in docs/proposals/DESIGN_NIX_PACKAGING.md in the murmuration repo.
