# Changelog

## 0.2.1 (2026-03-31)

### PTY

- Validate PTY size during startup as well as `resize/3`
- Remove generated PTY Zig wrapper file from the repo
- Ignore generated PTY Zig wrapper file going forward

### Build

- Make `mix ghostty.setup` copy `priv/` artifacts more robustly from the project root
- Refresh build `priv/` directories deterministically during setup

### Docs

- Use GitHub example links in README so HexDocs does not warn about missing local `examples/` paths

## 0.2.0 (2026-03-30)

### Terminal

- `input_key/2` — encode keyboard events to escape sequences
- `input_mouse/2` — encode mouse events (when tracking enabled)
- `encode_focus/1` — encode focus gained/lost
- `cells/1` — render state as grid of `{grapheme, fg, bg, flags}` tuples
- `Ghostty.Terminal.Cell` — flag helpers (`bold?/1`, `italic?/1`, etc.)
- Effect messages sent to the calling process:
  `{:pty_write, data}`, `:bell`, `:title_changed`
- Option validation — `ArgumentError` for invalid cols/rows/scrollback
- Graceful init failure — `{:error, reason}` instead of crash

### PTY

- Real pseudo-terminal via `forkpty()` NIF
- Programs like `vim`, `top`, `htop` work (child gets a real TTY)
- Non-blocking reader thread sends `{:data, binary}` messages
- `write/2`, `resize/3`, `close/1`
- Proper cleanup in destructor (SIGHUP, waitpid)

### LiveView

- `Ghostty.LiveTerminal` — Phoenix LiveView component
- `terminal/1` component with JS hook
- `handle_key/2` converts JS keyboard events to key encoding
- `priv/static/ghostty.js` — renders cell grid with colors and styles
- Optional: only compiles when `phoenix_live_view` is present

### Input

- `Ghostty.KeyEvent` — strict validation, raises on unknown keys
- `Ghostty.MouseEvent` — strict validation, raises on unknown buttons

### Build

- `mix ghostty.setup` — one-command contributor onboarding
- Precompiled NIFs via `zigler_precompiled`
- Precompile workflow builds and uploads terminal and PTY NIF artifacts for Linux x86_64, Linux aarch64, and macOS aarch64
- Precompiled terminal artifacts bundle `libghostty-vt` so clean installs work without manual setup
- Release workflow regenerates and commits `checksum-Ghostty.Terminal.Nif.exs` and `checksum-Ghostty.PTY.Nif.exs`
- zlint for Zig code

### Docs

- README examples are covered by tests
- Release/install flow documented in `AGENTS.md`

## 0.1.0 (2026-03-29)
