Add exponential backoff retry mechanism to handle ECONNREFUSED errors when the
server isn't ready yet during daemon startup. This includes:
- New errorUtils module with error classification helpers
- withRetry function in time.ts supporting configurable exponential backoff
- Machine registration retry with sensible defaults (60 attempts, 1-30s delays)
- Error refactoring to consolidate extractErrorInfo utility
close#35
Restructure CLI entry point and RPC handler registration to improve maintainability:
- Introduce command registry pattern with CommandDefinition interface for consistent command structure
- Extract individual command modules (claude, codex, daemon, doctor, gemini, auth, connect, etc.)
- Move RPC handlers into separate feature modules (bash, files, git, directories, ripgrep, difftastic, slashCommands)
- Create shared RPC types and response helpers (rpcTypes.ts, rpcResponses.ts)
- Move SpawnSessionOptions and SpawnSessionResult to rpcTypes for proper type organization
- Simplify index.ts to minimal entrypoint using command registry
- Update imports in apiMachine.ts and daemon/run.ts to use rpcTypes module
This enables:
- Better code organization by feature/command
- Easier testing of individual commands
- Safer RPC handler registration without side effects
- Clearer separation of concerns between routing and business logic
Implement comprehensive worktree session support allowing users to spawn sessions in temporary git worktrees. Includes backend worktree management, full-stack integration, and refined UI for session type selection.
Backend:
- Add worktree creation/removal utilities with branch management
- Track worktree metadata (basePath, branch, name, path) in session metadata
- Automatic cleanup of worktrees when sessions fail or exit
- Enhanced error handling with stderr tail logging
UI improvements:
- Redesign session type toggle with improved alignment and spacing
- Move worktree description inline with label for cleaner layout
- Add branch name input field that appears when worktree mode selected
- Auto-focus on worktree input when switching modes
- Reduce gap between radio options from gap-3 to gap-1.5
- Update descriptive text and placeholders for clarity
Integration:
- Thread worktree parameters through API client, RPC handlers, and daemon
- Add worktreeEnv utility to read worktree info from environment
- Update session spawning to support both simple and worktree modes
Consolidate process lifecycle management (kill, check alive) into a new
utility module with proper Windows/Unix handling, replacing scattered
process.kill() calls with consistent async APIs.
Remove tsx dependency and update all dev scripts and documentation to use bun
as the primary TypeScript runtime for development. Consolidate process detection
logic in daemon.ts to check for dev mode via src/index.ts regardless of runtime.
Complete documentation refresh covering:
- Version detection via CLI binary mtime (not package.json)
- Multi-Agent Support section with token authentication for claude/codex/gemini
- Directory creation approval flow for session spawning
- HTTP Control Server endpoints with Fastify + Zod schemas
- State persistence fields including startedWithCliMtimeMs
- Integration Testing section with test environment and key scenarios
- Typed shutdown sources (hapi-app, hapi-cli, os-signal, exception)
- MachineMetadata with new happyLibDir field
- WebSocket communication patterns and RPC methods
- Machine sync architecture with separated metadata and daemon state
Replaces CLAUDE.md with structured daemon documentation.
Replace CLI version string comparison with file modification time (mtime) based detection. This provides a more reliable way to detect when the CLI binary has been updated, especially for bun-compiled executables where package.json may not be accessible.
Changes:
- Add getInstalledCliMtimeMs() utility to check CLI binary or package.json mtime
- Store startedWithCliMtimeMs in daemon state on startup
- Use mtime comparison in version check loop for daemon auto-restart
- Move version flag handling to early CLI startup before daemon initialization
- Fix machine active state merging to prefer newer activeAt timestamp
This improves daemon restart behavior when CLI is updated via package managers.
Migrate HAPI CLI from npm-based distribution to Bun single-executable format:
- Remove npm bin wrappers (bin/happy.mjs, bin/happy-mcp.mjs)
- Simplify package.json: remove npm publish config (exports, main, module, types, files, publishConfig)
- Update bin entry to point to TypeScript source (src/index.ts)
- Migrate shebang from Node to Bun (#!/usr/bin/env bun)
- Simplify build scripts: remove npm-specific steps (pkgroll, prepublishOnly, release-it)
- Update spawnHappyCLI to support compiled binaries and development TypeScript mode
- Update daemon/doctor diagnostics for new process detection logic
- Production: use `bun build --compile` for single-executable releases
- Development: run TypeScript directly via `bun src/index.ts` or `tsx src/index.ts`
Consolidate CLI and server runtime directories from ~/.config/hapi/ (CLI) and ~/.hapi-server/ (Server) to a single ~/.hapi/ directory. Unify environment variables from HAPI_HOME_DIR (CLI) and HAPI_BOT_DATA_DIR (Server) to a single HAPI_HOME variable across both applications. Update all documentation and configuration references accordingly. Bump bun-types to 1.3.5.
This commit rebrands the project from "Happy" to "HAPI" throughout the codebase, including documentation, comments, logs, and tool references. It also adds comprehensive README files for the server and web components, clarifies the monorepo structure in AGENTS.md and root README.md, and removes the outdated roadmap.md file.
Changes include:
- Rebrand references from Happy to HAPI in CLI, server, and web components
- MCP tool names updated from mcp__happy__ to mcp__hapi__
- Process/service names updated consistently
- New server/README.md with deployment and configuration guide
- New web/README.md with stack and development instructions
- Updated root README.md with quickstart guide
- Updated AGENTS.md with cleaner structure documentation
- Removed cli/roadmap.md (now superseded by documentation)
Implements comprehensive ACP backend enabling integration with ACP-compliant agents like Gemini. Includes stdio transport, message handling, permission flow, and registry for agent management. Adds new 'hapi gemini' command to launch ACP agent sessions.
Enables building hapi as standalone Bun-compiled executables for macOS,
Linux, and Windows (x64/arm64). Adds build script, bootstrap entry point,
runtime asset management, and automatic deployment of bundled tools
(ripgrep, difftastic). Includes MCP stdio bridge support and proper
environment handling for compiled binaries. Updates documentation with
build and installation instructions for single executable distribution.
Introduce runtime path abstraction for Bun-compiled binaries that extracts
assets to ~/.happy/runtime/{version} instead of using project paths. This
enables proper distribution of CLI as a self-contained binary with embedded
tools (ripgrep, difftastic) and scripts that are extracted at runtime.
