In addition to the things you might expect, lightjj has the following cool features:\n\n- Includes a real merge tool with a 3-pane editor\n- Smart divergence resolution\n- File history\n- Review diffs with markdown preview, annotate lines with severity and comments, export to agent prompt, repeat\n- Works everywhere — locally, over SSH, or port-forwarded\n- Multi-repo, multi-workspace support\n\n## Core Features\n\n- **Revision graph** — SVG DAG, working-copy `@` indicator, immutable `◆` markers, bookmark badges with PR status\n- **Diff viewer** — unified/split, Lezer syntax highlighting, word-level diffs, context expansion, conflict A/B labels, open-in-$EDITOR\n- **Bookmarks panel** (`2`) — sync state at a glance: ahead/behind/diverged/conflict, PR badges, staleness. `d`/`f`/`t` for delete/forget/track, per-remote visibility toggles\n- **Inline rebase** — pick source (`-r`/`-s`/`-b`) and target (onto/after/before) modes, cursor to destination, Enter\n- **Multi-select** — batch abandon, squash, rebase across revisions with `Space`\n- **Op log \u0026 evolog** — full operation history with undo/restore, per-revision evolution with inter-diffs\n- **File history** — right-click any diff line, two-cursor compare (j/k + Space to pin), scoped to mutable for speed\n- **Inline annotations** — per-line review comments keyed by `change_id`; auto-re-anchor on rewrite; export markdown/JSON\n- **Stale-WC detection** — concurrent CLI op left the working copy stale? Warning bar with one-click recovery\n- **Themes** — 7 hand-tuned builtins + 486 derived from Ghostty's palette set; `t` toggles dark/light, full picker in Cmd+K\n\n## Install \u0026 Usage\n\n**One-line install** (macOS \u0026 Linux):\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/chronologos/lightjj/main/install.sh | sh\n```\n\nOr `go install` (requires Go \u003e= 1.21):\n\n```bash\ngo install github.com/chronologos/lightjj/cmd/lightjj@latest\n```\n\n**Run:**\n\n```bash\nlightjj                            # serve current repo, open browser\nlightjj -R /path/to/repo           # explicit repo path\nlightjj --addr localhost:8080      # custom listen address\nlightjj --no-browser               # don't auto-open browser\n```\n\n**Remote repos** — run on the remote and port-forward, or use SSH proxy mode:\n\n```bash\n# Port-forward\nssh -L 3001:localhost:3001 user@host \\\n  \"lightjj -R /path/to/repo --addr localhost:3001 --no-browser\"\n\n# SSH proxy mode\nlightjj --remote user@host:/path\n```\n\nSSH proxy mode adds ~400ms per command (reduce to ~20ms with ControlMaster). Auto-refresh polls on `--snapshot-interval` (default 5s), snapshotting the remote working copy automatically.\n\n**Updating:** re-run the install command. Check your version with `lightjj --version`.\n\n## Roadmap\n\n|         | Theme                 |                                                                                              |\n| ------- | --------------------- | -------------------------------------------------------------------------------------------- |\n| **1.0** | Ship-ready core       | done                                                                                         |\n| **2.0** | Code editing \u0026 review | Mega-file virtualization, cross-revision search, N-way conflict resolution, LSP-in-FileEditor |\n| **3.0** | Agentic               | Annotations as a library, agent-writable API, MCP server mode                                |\n\n## Requirements\n\n- **jj \u003e= 0.39**\n- **Go \u003e= 1.21** — only if building from source\n- **gh** (optional) — for PR badges; must be authed wherever the repo lives\n\n## Development\n\n```bash\n# Two terminals:\ngo run ./cmd/lightjj --addr localhost:3000 --no-browser   # backend\ncd frontend \u0026\u0026 pnpm run dev                                # frontend (Vite HMR)\n\n# Tests\ngo test ./...              # Go\ncd frontend \u0026\u0026 pnpm test   # Vitest\n```\n\nSee [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) for system design and [docs/CONFIG.md](docs/CONFIG.md) for configuration.\n\n## Upstream\n\nCore command builder patterns ported from [jjui](https://github.com/idursun/jjui).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchronologos%2Flightjj","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fchronologos%2Flightjj","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchronologos%2Flightjj/lists"}
