## What's New

### 0.42.0

Universal macOS binaries — one signed/notarized download runs natively on both Apple Silicon and Intel.

- **Universal macOS binary** (`par-term-macos-universal.zip`) — a single build covering both aarch64 and x86_64, so an Apple-Silicon user who grabs the Intel build no longer runs under Rosetta or hits the "Support ending for Intel-based apps" prompt. The self-updater now prefers the Universal asset and falls back to per-arch on older releases; per-arch downloads still work. (#223)
- **Command-history log is char-boundary-safe** — truncating the rendered line for the history overlay no longer panics on non-ASCII (CJK, emoji) text.
- **`par-term-emu-core-rust` bumped to 0.46** (latest), with the `pty_session` feature now explicitly enabled.

### 0.41.0

A new **Disk Free** status-bar widget shows free disk space as `DISK  62% (250.0 GB free)`.

- **Disk Free widget** (`status_bar: disk_free`) — free space as percent + bytes, cross-platform via `sysinfo`. Defaults to the disk par-term was launched from at a 60-second poll interval (`status_bar_disk_poll_interval`); enable `status_bar_disk_follow_cwd` to follow the active tab/pane's working directory instead. Adds `system.disk_free`, `system.disk_free_percent`, and `system.disk_total` interpolation variables for custom widgets. Disabled by default.

### 0.40.0

Script restart policies now work for observer scripts. `restart_policy` and `restart_delay_ms` had been parsed and shown in the Settings UI since 0.38.0 but never enforced.

- **Scripts honor `restart_policy` / `restart_delay_ms`** (`never`, `always`, `on_failure`) — a script that exits is restarted per its policy after the configured delay, matching how coprocesses already worked. `on_failure` tells a crash from a clean exit, and a crash-loop guard caps restarts at five within a five-second grace window. Closes #222.
- **Dead scripts are reaped on exit** instead of lingering with their terminal observer still attached until the tab was closed.

### 0.39.0

A maintenance release. No new features and no behavioural fixes, but it clears two high-severity security advisories and removes 18 crates from the dependency graph.

- **Two `quick-xml` advisories are cleared** (RUSTSEC-2026-0194 and -0195) by updating past the constraint that pinned it. Real exposure was low — the crate reaches par-term only through a build-time proc-macro parsing bundled Wayland protocol XML, on Linux — but `cargo audit` is clean again.
- **The dead `mermaid` feature is gone**, along with `mermaid-rs-renderer` and `resvg`. Nothing had referenced them since 0.31.0 removed the content prettifier, yet the feature stayed in the default set, so every build compiled and linked an entire SVG rasterization stack. Drops 18 crates.
- **Rust 1.97.1**, with the minimum supported version raised to 1.97, and 105 dependencies refreshed.
- **`make package` and `make secret-scan` work again** — the first had been broken since the initial commit, copying a `LICENSE-MIT` file that never existed.

> **Breaking for library consumers only:** the MSRV is now 1.97, and `--features mermaid` no longer exists. Users of the released binaries are unaffected.

Release notes for every earlier version live in [CHANGELOG.md](CHANGELOG.md).

### 0.38.0

The result of a full security, architecture, quality and documentation audit — the largest release so far. Three changes break a working setup; they are listed first.

> **Upgrading from 0.37.1 or earlier:** **Check for Updates** will not install it — download by hand once. Those releases published no per-binary checksums and those builds carry no signing key, so both self-update gates refuse. Self-update works normally from 0.38.0 onward. See the [migration guide](docs/guides/MIGRATION.md#v0380--upgrading-requires-a-manual-download).

**Breaking**

- **Importing preferences from a URL now requires HTTPS** -- an `http://` import URL stops working. The same path also used to abort the process outright on any HTTPS URL, so in practice it only ever worked over plaintext.
- **A profile's command asks for confirmation before it runs** -- profile matching is driven by the hostname a remote shell reports, so it is remote-controlled input. There is no opt-out.
- **`Cmd/Ctrl+Shift+P` now toggles the profile drawer**, which is what the settings table always advertised; **Manage Profiles** keeps its menu entry but loses the accelerator.

**Added**

- **Linux has a menu bar** -- New Window, Close Window, Quit and Select All were menu-only actions on a platform with no menu, so there was no way to reach them at all. All four are now bindable on every platform.
- **The session survives a panic** -- the event loop publishes a pre-serialized capture every few seconds and the panic hook writes it, so a crash no longer costs every tab its working directory.
- **Duplicate Tab has a default binding** (`Cmd/Ctrl+Shift+J`), and tab reordering appears in the menu.
- **`XDG_CONFIG_HOME` is honoured on Linux and macOS**, and macOS user data moves under `~/.config/par-term/` with a one-time automatic migration.

**Security and stability**

- **A malicious mDNS hostname could reach a shell** through Quick Connect; every SSH argument is now validated and quoted.
- **Any emoji, CJK character or accented letter could crash the terminal** -- six sites used a grid column index as a UTF-8 byte offset. They survived 1,965 green tests because every test input in the repository was ASCII.
- **A failed pane demote destroyed every terminal in the source tab**, silently.
- **Scripting did nothing unless the Settings window was open** -- the entire script runtime sat behind that branch.
- **Update downloads are signature-verified** and release assets are signed, notarized and checksummed.
- **Every pane is submitted to the GPU in one submit instead of one each**, and the full cell grid is no longer deep-cloned on idle frames.

## Installation

### Homebrew (macOS)

```bash
brew install --cask paulrobello/tap/par-term
```

### Cargo Install

If you have a Rust toolchain installed, install directly from crates.io:

```bash
cargo install par-term
```

This builds and installs the binary to `~/.cargo/bin/par-term`.

### From Source

Requires Rust 1.97+ (stable, 2024 edition) and modern graphics drivers:

```bash
# Clone the repository
git clone https://github.com/paulrobello/par-term
cd par-term

# Build with the optimized dev-release profile (~1m20s clean, ~1-2s incremental, ~90-95% of full release performance)
make build

# Run
make run

# Or build the full release binary (~3 min, for distribution)
make build-full

# Install Claude ACP bridge for Assistant Panel (Claude connector)
make install-acp
```

> **Note:** The legacy package `@zed-industries/claude-code-acp` was renamed/deprecated upstream. Use `@zed-industries/claude-agent-acp` (`claude-agent-acp` binary).

### macOS Bundle

To create a native macOS `.app` bundle with a dock icon:

```bash
make bundle
make run-bundle
```

To build and install the app bundle plus the CLI binary and Claude ACP bridge in one step:

```bash
make bundle-install
```

### Linux Dependencies

On Linux, you need GTK3 and X11/Wayland libraries. Install the appropriate packages for your distribution:

**Ubuntu/Debian**:
```bash
sudo apt install libgtk-3-dev libxkbcommon-dev libwayland-dev libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libasound2-dev
```

**Fedora/RHEL**:
```bash
sudo dnf install gtk3-devel libxkbcommon-devel wayland-devel libxcb-devel alsa-lib-devel
```

**Arch Linux**:
```bash
sudo pacman -S gtk3 libxkbcommon wayland libxcb alsa-lib
```

### macOS Gatekeeper Notice

If macOS reports that par-term "is damaged and can't be opened", this is caused by the Gatekeeper quarantine attribute applied to unsigned binaries. Remove it with:

```bash
# For the release binary
xattr -cr target/release/par-term

# For the .app bundle
xattr -cr /Applications/par-term.app
```

> **Note:** The Homebrew cask install (`brew install --cask paulrobello/tap/par-term`) handles this automatically.

## Installing Shaders

par-term includes 73 custom GLSL shaders for background effects and cursor animations. These need to be installed to your config directory.

### Built-in Installer (Recommended)

Use the built-in CLI command to download and install all shaders from the latest release:

```bash
# Install shaders (with confirmation prompt)
par-term install-shaders

# Install without prompts
par-term install-shaders -y

# Force overwrite existing shaders
par-term install-shaders --force
```

### Shell Script

Alternatively, use the shell script installer. The recommended approach is to
download the script first, inspect it, and then run it:

```bash
# Recommended: download, inspect, then run
curl -O https://raw.githubusercontent.com/paulrobello/par-term/main/install_shaders.sh
# Review the script before executing:
less install_shaders.sh
chmod +x install_shaders.sh
./install_shaders.sh
```

> **Note**: The one-liner pipe-to-shell pattern executes remote code without
> review. Use the download-then-inspect workflow above when security matters.

```bash
# Convenience only — inspect the script first when possible
curl -sL https://raw.githubusercontent.com/paulrobello/par-term/main/install_shaders.sh | sh
```

### Manual Install

1. Download `shaders.zip` from the [latest release](https://github.com/paulrobello/par-term/releases/latest)
2. Extract to your config directory:
   - **macOS/Linux**: `~/.config/par-term/shaders/`
   - **Windows**: `%APPDATA%\par-term\shaders\`

### From Source

If building from source, copy the shaders folder manually:
```bash
# macOS/Linux
cp -r shaders ~/.config/par-term/

# Windows (PowerShell)
Copy-Item -Recurse shaders $env:APPDATA\par-term\
```

### Using Shaders

Once installed, enable shaders in your `config.yaml`:
```yaml
# Background shader
custom_shader: "starfield.glsl"
custom_shader_enabled: true

# Cursor shader
cursor_shader: "cursor_glow.glsl"
cursor_shader_enabled: true
```

See the [Shader Gallery](docs/features/SHADERS.md) for previews of all included shaders.

### Linting Shaders

Validate shader metadata, channel references, and control comments from Settings > Effects > Custom Shaders with **Run Lint** (and clear the current output with **Clear Lint**), or from the CLI with:

```bash
par-term shader-lint ~/.config/par-term/shaders/my-shader.glsl
```

Add `--readability` to print a readability score plus suggested `custom_shader_brightness` and `custom_shader_text_opacity` defaults. By default, readability mode prompts before writing those suggestions into shader metadata:

```bash
par-term shader-lint my-shader.glsl --readability
par-term shader-lint my-shader.glsl --apply       # apply suggestions without prompting
par-term shader-lint my-shader.glsl --readability --no-prompt
```

## Keyboard Shortcuts

Essential shortcuts to get started. On macOS, keybindings use `Cmd`; on Linux/Windows, they use `Ctrl+Shift` to avoid conflicts with terminal control codes.

| Shortcut | Action |
|----------|--------|
| `Cmd/Ctrl + T` | New tab |
| `Cmd/Ctrl + W` | Close tab (or window if single tab) |
| `Cmd/Ctrl + N` | New window |
| `Cmd/Ctrl + C` | Copy selection |
| `Cmd/Ctrl + V` | Paste from clipboard |
| `Cmd/Ctrl + F` | Open search |
| `Cmd/Ctrl + D` | Split pane horizontally |
| `F5` | Reload configuration |
| `F11` | Toggle fullscreen |
| `F12` / `Cmd + ,` | Open Settings |

See the [full keyboard shortcuts reference](docs/guides/KEYBOARD_SHORTCUTS.md) for the complete list, including copy mode, pane management, shader toggles, SSH quick connect, and all customizable keybindings.
