released in progress planned
0.1.0

Initial Release

2026-03-31 released

Terminal emulator, built-in multiplexer, and full AI integration stack.

  • VT100/xterm state machine (CSI, SGR 256+truecolor, OSC, DCS passthrough)
  • CPU SIMD rendering via @Vector — no GPU, <50μs per frame
  • Multi-pane with 4 tiling layouts (master-stack, grid, monocle, floating)
  • 9 workspaces, Ctrl+Space prefix keys
  • CustomPaneBackend protocol for Claude Code agent teams (7 operations)
  • MCP server (6 tools over Unix socket)
  • OSC 9999 agent self-declaration protocol
  • Process graph (DAG with agent metadata)
  • Session save/restore with binary serialization
  • Command-stream scrollback compression (20-50x)
  • X11 via pure XCB, Wayland via xdg-shell
  • Config file: ~/.config/teru/teru.conf
  • Hook system (spawn/close/agent_start/session_save)
0.1.1

Clipboard & AUR

2026-03-31 released

Clipboard auto-detection, Wayland keyboard fix, and AUR package.

  • Clipboard: auto-detect display server (wl-copy on Wayland, xclip on X11)
  • Build: link libxkbcommon for Wayland-only builds (keyboard was broken with -Dx11=false)
  • Keyboard: enable xkbcommon translation for both X11 and Wayland backends
  • AUR package live: paru -S teru
  • Makefile with build profiles (make dev, make release, make install)
0.1.2

Full AI Integration

2026-04-01 released

Three-layer AI integration fully wired: PaneBackend + HookListener + MCP Server.

  • Claude Code hook listener: Unix socket HTTP server accepts 16 lifecycle event types
  • HookHandler expanded from 5 to 16 events (PreToolUse, PostToolUse, SessionStart/End, Stop, Notification, PreCompact/PostCompact)
  • processHookEvent dispatches to ProcessGraph (agent spawn/stop/pause, tool activity)
  • Full project roadmap added
0.1.3

Prefix Key & Pane Controls

2026-04-01 released

Configurable prefix key, pane zoom, and pane resize.

  • Configurable prefix key: prefix_key = ctrl+b in teru.conf
  • Pane zoom: Ctrl+Space, z toggles between current layout and monocle
  • Pane resize: Ctrl+Space, H/L adjusts master ratio in master-stack (15%-85%)
0.1.4

Wayland Parity + Copy Mode

planned

Proper Wayland keyboard integration and vi-like copy mode.

  • Wayland keyboard: use compositor keymap FD via xkb_keymap_new_from_fd()
  • Copy mode: vi-like scrollback navigation (Ctrl+Space,[ enters, hjkl/v/y)
  • Custom keybindings in config file (key=action mapping)
0.1.5

Terminal Basics

planned

Kitty keyboard protocol, shell integration, and improved search.

  • Kitty keyboard protocol (disambiguate press/release/repeat, modifier encoding)
  • Shell integration scripts (bash/zsh/fish auto-inject OSC 133 emitters)
  • Scrollback search improvement (persist query, highlight count, next/prev match)
0.2.0

Detach/Attach Daemon

planned

Background daemon process — sessions persist across terminal restarts.

  • Daemon mode (teru-server background process owns PTYs)
  • teru attach (client connects to running daemon)
  • teru detach (disconnect client, daemon keeps PTYs alive)
  • Named sessions (teru new -s work, teru attach work)
  • Session persistence across terminal restarts
0.3.0

Graphics + Full Unicode

planned

Kitty graphics protocol, Sixel, emoji, CJK, and font fallbacks.

  • Kitty graphics protocol (bitmap display, streaming, placement)
  • Sixel graphics (legacy image protocol)
  • Full Unicode: emoji via COLR/CPAL tables
  • Full Unicode: CJK double-width characters (wcwidth)
  • Font fallback chains (Hack → Noto → system fonts)
0.4.0

Plugin System

planned

WASM plugin runtime with hooks, render, and tool APIs.

  • WASM plugin runtime (sandboxed)
  • Plugin API: hooks (on_key, on_output, on_resize, on_agent_event)
  • Plugin API: render (custom status bar widgets, overlays)
  • Plugin API: tools (register MCP tools from plugins)
  • Lua scripting bridge (Lua 5.4 for config/keybind scripting)
0.5.0

AI-First Features

planned

Context gauge, cost tracking, cross-pane approval, process graph visualization.

  • Context compaction gauge (status bar shows Claude Code context usage %)
  • Agent cost tracking (accumulate tokens from hook metadata, show per-agent cost)
  • Cross-pane approval (permission_prompt hook → inline yes/no widget)
  • Auto-workspace for teams (spawn_agent with group → dedicated workspace)
  • Process graph visualization (Ctrl+Space,g — DAG view)
  • Agent replay (rewind session using scrollback + event timestamps)
0.6.0

macOS

planned

Fix AppKit backend, PTY, Homebrew tap.

  • Fix AppKit backend for Zig 0.16
  • PTY via forkpty() from util.h
  • Keyboard via Carbon UCKeyTranslate
  • Clipboard via pbcopy/pbpaste
  • Homebrew tap (nicholasglazer/homebrew-teru)
  • Retina/HiDPI support
0.7.0

Windows

ConPTY, Win32 keyboard, winget + Scoop.

  • ConPTY (CreatePseudoConsole, Win10 1809+)
  • Win32 keyboard translation
  • Clipboard (OpenClipboard + SetClipboardData)
  • Scoop bucket + WinGet manifest
0.8.0

SDK Integration

planned

Claude Code SDK embedding, headless sessions, and session recording.

  • Claude Code SDK embedding (optional Node.js/Python process for terminal-native AI chat)
  • Headless session spawning (claude -p --output-format stream-json, NDJSON parsing)
  • Session recording with semantic markup (commands, agent events, timing)
  • Session replay (searchable, shareable recordings)
