feat(cli): add --version flag and Homebrew tap scaffolding (#46) - #58
Merged
Conversation
Adds a top-level `--version` flag (and `gander version` subcommand) that prints the version and exits 0. This lets the Homebrew formula's `test do` block assert the version string without triggering `fetchLatestRelease` (which would fail in Homebrew's network-isolated sandbox). Rewrites the README install section so Homebrew leads: brew tap gandermd/gander brew install gander The `curl | bash install.sh` one-liner is demoted to a 'fallback / non-Homebrew systems' subsection; the rest of the install flow is unchanged. Adds `scripts/bump-homebrew.sh <version>`, a thin wrapper around `brew bump-formula-pr` that opens a PR against gandermd/homebrew-gander after each release. Documented in the Releasing section.

--versionwas needed for the Homebrew formula'stest doblock: running the binary with no args hitsrunNoArg, which callsfetchLatestRelease()— that touches the network and is blocked in Homebrew's sandbox. With--version, the test can assert the version string instead.gander-{goos}-{goarch}) is unchanged.assetNameForRuntimeinupgrade.gocontinues to match.gander --upgradecontinues to work for users installed via Homebrew: the GitHub release URL contract is unchanged.
