From 366b340f9fd8b36c0f3f2a9a730af092fce1a212 Mon Sep 17 00:00:00 2001 From: Lucas Modrich Date: Sun, 5 Oct 2025 10:07:04 +1100 Subject: [PATCH 1/5] feat: rename Go CLI binary to gwtm for improved usability MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGE: Binary name changed from git-worktree-manager to gwtm The shorter binary name (4 chars vs 20 chars) significantly improves user experience by reducing typing friction. This follows industry standards where popular CLI tools use memorable short names (gh, kubectl, helm, hugo). Changes: - Update Makefile to build 'gwtm' binary - Update .goreleaser.yml for multi-platform releases - Update GitHub Actions workflows to use new binary name - Add migration guide in README.md with symlink instructions - Update CLAUDE.md with build instructions - Add complete Go CLI implementation with Cobra framework - Update constitution to document multi-implementation strategy The Bash script (git-worktree-manager.sh) remains unchanged. Migration path for existing users: ln -s $(which gwtm) /usr/local/bin/git-worktree-manager ๐Ÿค– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .github/workflows/release.yml | 26 +- .github/workflows/test.yml | 45 +- .goreleaser.yml | 56 ++ .specify/memory/constitution.md | 141 ++++- CLAUDE.md | 32 +- Makefile | 34 ++ README.md | 126 +++- cmd/git-worktree-manager/main.go | 20 + go.mod | 9 + go.sum | 10 + internal/commands/branch.go | 146 +++++ internal/commands/list.go | 50 ++ internal/commands/prune.go | 45 ++ internal/commands/remove.go | 78 +++ internal/commands/root.go | 49 ++ internal/commands/setup.go | 145 +++++ internal/commands/upgrade.go | 62 ++ internal/commands/utils.go | 27 + internal/commands/version.go | 79 +++ internal/config/env.go | 22 + internal/config/env_test.go | 61 ++ internal/config/paths.go | 11 + internal/config/paths_test.go | 67 +++ internal/git/branch.go | 63 ++ internal/git/branch_test.go | 186 ++++++ internal/git/client.go | 56 ++ internal/git/client_test.go | 124 ++++ internal/git/config.go | 43 ++ internal/git/config_test.go | 142 +++++ internal/git/remote.go | 109 ++++ internal/git/remote_test.go | 198 ++++++ internal/git/worktree.go | 71 +++ internal/git/worktree_test.go | 126 ++++ internal/ui/errors.go | 16 + internal/ui/errors_test.go | 68 +++ internal/ui/output.go | 20 + internal/ui/output_test.go | 133 ++++ internal/ui/prompt.go | 40 ++ internal/ui/prompt_test.go | 107 ++++ internal/version/semver.go | 148 +++++ internal/version/semver_test.go | 178 ++++++ internal/version/upgrade.go | 178 ++++++ specs/001-i-would-like/spec.md | 116 ++++ .../contracts/cli-interface.md | 504 ++++++++++++++++ specs/002-go-cli-redesign/data-model.md | 316 ++++++++++ specs/002-go-cli-redesign/plan.md | 247 ++++++++ specs/002-go-cli-redesign/quickstart.md | 568 ++++++++++++++++++ specs/002-go-cli-redesign/research.md | 443 ++++++++++++++ specs/002-go-cli-redesign/spec.md | 197 ++++++ specs/002-go-cli-redesign/tasks.md | 501 +++++++++++++++ specs/003-002-go-cli/spec.md | 116 ++++ 51 files changed, 6308 insertions(+), 47 deletions(-) create mode 100644 .goreleaser.yml create mode 100644 Makefile create mode 100644 cmd/git-worktree-manager/main.go create mode 100644 go.mod create mode 100644 go.sum create mode 100644 internal/commands/branch.go create mode 100644 internal/commands/list.go create mode 100644 internal/commands/prune.go create mode 100644 internal/commands/remove.go create mode 100644 internal/commands/root.go create mode 100644 internal/commands/setup.go create mode 100644 internal/commands/upgrade.go create mode 100644 internal/commands/utils.go create mode 100644 internal/commands/version.go create mode 100644 internal/config/env.go create mode 100644 internal/config/env_test.go create mode 100644 internal/config/paths.go create mode 100644 internal/config/paths_test.go create mode 100644 internal/git/branch.go create mode 100644 internal/git/branch_test.go create mode 100644 internal/git/client.go create mode 100644 internal/git/client_test.go create mode 100644 internal/git/config.go create mode 100644 internal/git/config_test.go create mode 100644 internal/git/remote.go create mode 100644 internal/git/remote_test.go create mode 100644 internal/git/worktree.go create mode 100644 internal/git/worktree_test.go create mode 100644 internal/ui/errors.go create mode 100644 internal/ui/errors_test.go create mode 100644 internal/ui/output.go create mode 100644 internal/ui/output_test.go create mode 100644 internal/ui/prompt.go create mode 100644 internal/ui/prompt_test.go create mode 100644 internal/version/semver.go create mode 100644 internal/version/semver_test.go create mode 100644 internal/version/upgrade.go create mode 100644 specs/001-i-would-like/spec.md create mode 100644 specs/002-go-cli-redesign/contracts/cli-interface.md create mode 100644 specs/002-go-cli-redesign/data-model.md create mode 100644 specs/002-go-cli-redesign/plan.md create mode 100644 specs/002-go-cli-redesign/quickstart.md create mode 100644 specs/002-go-cli-redesign/research.md create mode 100644 specs/002-go-cli-redesign/spec.md create mode 100644 specs/002-go-cli-redesign/tasks.md create mode 100644 specs/003-002-go-cli/spec.md diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 77dc8e9..ed9290d 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -18,10 +18,30 @@ jobs: with: node-version: 20 -

(unchanged): +git-worktree-manager.sh / +git-worktree-manager.sh --new-branch [base] +# ... same flags and syntax +``` + +**Contract Validation**: +- All tests remain valid; simply replace binary name

If confirmed, the system checks if the branch exists on the remote repository. If the branch does not exist remotely, the system prompts the user for confirmation to push the branch to the remote. +- When a user tries to create a worktree for a branch that exists remotely but not locally, the system prompts the user for confirmation, then fetches the remote branch and creates the worktree from it if the user confirms. +- When network failures occur during clone or fetch operations, the system prompts the user whether to retry the operation or abort, allowing the user to decide based on their network situation. +- When GitHub API rate limits are hit during version checks, the system fails with a clear error message and suggests the user try again later when the rate limit resets. +- When repositories have renamed their default branch (e.g., from 'master' to 'main'), the system automatically detects the current default branch using git symbolic-ref and prompts the user to confirm the detected default branch before proceeding with setup. +- When a user
