feat: Auto-update Homebrew tap on release (closes #28)#31
Merged
Conversation
The fummicc1/homebrew-tap formulae were bootstrapped manually for v0.1.0, so they would drift from every subsequent release without a sync step. Add an update-homebrew-tap job that, on each non-prerelease tag, fetches the per-arch .sha256 release assets and rewrites the version and sha256 fields in both tap formulae, then pushes via a GitHub App token (no PAT). The patch script anchors on each formula url line so it handles the multi-arch on_macos/on_linux block layout without positional fragility. Also document brew install in the CLI and MCP README sections. Claude-Session: https://claude.ai/code/session_01QvZLELvJyEvSiR4SadiSt2

Use the App's own bot identity (fummicc1-app[bot]) for tap commits instead of github-actions[bot], resolving the slug and numeric user id from the App token so the noreply email is valid and commits verify under the App. Claude-Session: https://claude.ai/code/session_01QvZLELvJyEvSiR4SadiSt2

Summary
Completes the
brew install fummicc1/tap/swift-complexitydistribution requested in #28.The tap repository
fummicc1/homebrew-tapand its formulae (swift-complexity.rb/swift-complexity-mcp.rb) were already bootstrapped manually for v0.1.0, but this repository was missing (1) a mechanism to keep the formulae in sync with every release, and (2)brew installinstructions in the README. This PR fills both gaps.Changes
.github/scripts/update_formula.py(new): Rewrites theversionand per-architecturesha256fields by fetching the.sha256assets attached to the release. It anchors on each formulaurlline to map the immediately followingsha256line, so it handles the multi-archon_macos/on_linuxblock layout without positional fragility. Standard library only..github/workflows/release.yml: Adds anupdate-homebrew-tapjob. It runs aftercreate-release, only for non-prereleases. It checks out the tap with a GitHub App token (not a PAT), updates both formulae via the script, then commits & pushes.README.md: Documentsbrew installin the CLI and MCP Installation sections.Prerequisites (post-merge user action⚠️ )
The auto-update job requires the following, which cannot be configured in code:
Contents: Read and writepermission, installed onfummicc1/homebrew-tap.HOMEBREW_TAP_APP_IDandHOMEBREW_TAP_APP_PRIVATE_KEYin this repository.If unset, only this job fails; the release itself (
create-release) is unaffected.Verification
update_formula.py 0.1.0against the current tap formulae reproduces the existingversionandsha256values exactly (idempotency proves the substitution logic is correct).python3 ast.parseconfirms valid syntax.actionlintparsesrelease.ymlsuccessfully (warnings are limited to pre-existing steps; the new job is clean).brew installformatting in the README.https://claude.ai/code/session_01QvZLELvJyEvSiR4SadiSt2
