l0ng-ai 5003c4d733 feat(editor): language servers for the code editor
A new ui::lsp module runs language servers for local files the editor
opens: rust-analyzer, typescript-language-server, pyright (or pylsp),
gopls and clangd, from a registry table. Each server is keyed by
(server, project root), found from markers such as a Cargo workspace,
package.json, go.work/go.mod or pyproject.toml, and shared by every buffer
under that root. A server missing from PATH (which tty7 already fills from
the login shell) means no LSP for that language and a one-line hint in the
status bar.

The JSON-RPC client frames Content-Length messages over the server's stdio
on dedicated threads, holds everything back until initialize is answered,
cancels requests nobody waits for any more, and answers the server's own
requests (configuration, capability registration, applyEdit). Documents
use full-text sync, debounced, and flushed before every request. A server
whose last file closed shuts down after a grace period, every server exits
with the app, and one that crashes is restarted a few times before it is
left down.

Features: diagnostics as underlines with hover messages and an error and
warning count in the status bar; completion (snippets flattened to plain
text); hover; go to definition by secondary-click or F12, across files
through open_file_in_editor_at; code actions on the editor's own menu
(cmd-.), resolved and executed as the server needs; Format Document
(shift-alt-f); and Rename Symbol (F2) in the editor's bar, applied to open
buffers and to files on disk. The key bindings sit in the Input context so
F2 and F12 stay with terminal programs.

Positions are converted at the boundary: servers count UTF-16 units,
gpui-component counts chars, and the rope counts bytes.

The new editor_lsp setting (default on) turns it all off.

One-minute tour of tty7: agents across repos, one agent driving another through the CLI, the prompt editor, diffs, dragging panes, and sessions that survive quitting the app

▶ Watch in full quality

Why

A background server owns your shells and panes — not the window. Everything below follows from that.

  • Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
  • Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
  • Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
  • Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
  • Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack

Install

Native builds for macOS, Windows, and Linux on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Agent-aware per-pane detection (26 CLIs) · status dot · notifications · branch + diff · tray icon when input is needed · resume after reboot · reopen any past session from Search Everywhere · one-key launch · tab sidebar grouped by repository, with pinned groups
CLI + Skills bundled tty7 CLI · agent skill · run streams a command and exits with its code · split · send · wait --until free · capture
Editor-grade input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P Search Everywhere · ⌘ F scrollback search · hibernate a tab to free its memory · IME
Side panel ⌘ J · process tree and listening ports · file tree · changes and diffs · find in files · GitHub issues and pull requests, read-only, signed in through gh
Customization 13 built-in themes · your own YAML · iTerm2 color import · rebindable shortcuts · English, 简体中文, 日本語 interface
Shell integration injected when a pane starts, nothing to install · prompt marks · working directory · exit codes · command-finished notifications · zsh, bash, fish, PowerShell, WSL, remote panes
Remote workspaces remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off
SSH native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install

Supported agents

Detection is free: brand avatar, branch + diff, tab title. Status takes one click under Settings → Integrations to install that agent's hook, and brings the status dot, notifications, the tray icon, tty7 wait, and resume after a reboot. Fork needs both — the agent's own fork command, and the hook that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get, in a normal PTY, with its own interface. An agent launched through a wrapper script can be mapped to one by name with agent_commands in config.json. Every agent on your PATH is also a row in Search Everywhere (Agent: Claude Code, …) that opens it in a new tab, and the New Tab menu names the ones you have actually run. agent_launch sets the command line it starts with.

Documentation

Full documentation lives in docs/ — keyboard shortcuts · config.json · CLI reference. The agent-facing CLI interface is also documented in skills/tty7/SKILL.md.
