The Python CLI is currently the shipped `apm` command +via PyInstaller packaging and `pip install apm-cli`. + +The Go CLI currently implements: +- `apm --help` / `apm --version` (full parity with Python) +- `apm init [--yes] [PROJECT_NAME]` (functional, creates apm.yml) +- Per-command `--help` for all 26 commands (golden-file verified) + +Remaining commands return a "not yet fully implemented" message. + +## Cutover Trigger Conditions + +The Go binary becomes the shipped `apm` command when ALL of the following +are true: + +1. All 26 commands respond correctly to `--help` (done) +2. The representative command matrix passes functional tests: + `init`, `install`, `update`, `compile`, `pack`, `run`, `audit`, + `policy`, `mcp`, `runtime`, `targets`, `list`, `view`, `cache`, + `deps`, `marketplace`, `uninstall`, `prune` +3. Python-vs-Go parity tests pass for all commands in the matrix +4. `go build ./cmd/apm` produces a single static binary +5. CI passes on the crane PR branch (`crane/crane-migration-python-to-go-full-apm-cli-rewrite`) + +## Cutover Steps + +When conditions are met: + +1. Update `pyproject.toml` to add `[project.scripts]` pointing to the + Go binary wrapper OR replace the `apm` entrypoint with a shim that + calls the Go binary. +2. Update `build/apm.spec` (PyInstaller) to be marked deprecated/archived. +3. Update `install.sh` and `install.ps1` to download the Go binary. +4. Tag a release with `goreleaser` (or equivalent) producing platform + binaries. +5. Update `README.md` install instructions to reference the Go binary. + +## Python Compatibility Shim + +Until all commands are implemented in Go, the Python CLI remains the +authoritative `apm` command. The Go binary is available as `apm-go` +for testing. + +The shim removal plan: once the command matrix passes functional tests, +the Python entrypoint is replaced by the Go binary in the same PR that +passes the final parity tests. + +## Timeline + +Each Crane iteration advances one or more commands. At the current pace +(one iteration every 20 minutes), full command coverage is expected +within ~10 additional iterations. diff --git a/cmd/apm/apmyml.go b/cmd/apm/apmyml.go new file mode 100644 index 00000000..02f0316c --- /dev/null +++ b/cmd/apm/apmyml.go @@ -0,0 +1,191 @@ +// apmyml.go provides a minimal apm.yml parser for the Go CLI rewrite. +// Only the fields needed for read-only CLI commands are parsed. +package main + +import ( + "bufio" + "fmt" + "os" + "path/filepath" + "strings" +) + +// ApmProject holds the parsed apm.yml structure. +type ApmProject struct { + Name string + Version string + Description string + Author string + Targets []string + Scripts map[string]string + Deps []ApmDep + MCPDeps []ApmDep + Marketplaces []ApmMarketplace +} + +// ApmDep is a single dependency entry (owner/repo or owner/repo@ref). +type ApmDep struct { + Package string + Ref string +} + +// ApmMarketplace is a registered marketplace source. +type ApmMarketplace struct { + Name string + URL string +} + +// findApmYML walks up from dir looking for apm.yml. +func findApmYML(dir string) (string, error) { + current := dir + for { + candidate := filepath.Join(current, "apm.yml") + if _, err := os.Stat(candidate);
