Reimplement ralph-loop in TypeScript with Bun runtime#6
Conversation
Port the Ruby ralph-loop.rb parallel Claude runner to TypeScript, targeting the Bun runtime for native TS execution without a build step. https://claude.ai/code/session_017U4Gj5uNfcEJk3uLYeM9p2
36 tests covering rendering, state queries, config loading, PRD I/O, state mutation, process management, cleanup, and task list display. Exports class and helpers with guarded entry point for testability. https://claude.ai/code/session_017U4Gj5uNfcEJk3uLYeM9p2
- Fix: cleanup was sending signals to process groups that were never created (Bun.spawn has no pgroup option). Now uses proc.kill() directly. - Fix: remove bash shell wrapper; use Bun.file() for stdin, eliminating shell injection surface and the shellEscape method entirely. - Consolidate runningPids + processGroups + subprocesses into a single subprocesses Map (Bun.Subprocess provides .pid, .kill(), .exitCode). - Extract banner art into const arrays, render with a loop. - Remove unnecessary async from checkRunningTasks (no awaits). - Add missing break statements in switch/case after process.exit calls. - Tests: use new RalphLoop() instead of Object.create, add withDir helper, remove unused imports. 34 tests pass. https://claude.ai/code/session_017U4Gj5uNfcEJk3uLYeM9p2
