# ashell
![Preview](preview.png)
`ashell` is a modern, GPUI Component-based desktop terminal client written in Rust.
This project focuses on providing a high-performance and visually appealing shell workspace by combining local and remote environments with a rich set of built-in features.
## 🚀 v0.4 Major Upgrades
v0.4 builds on the v0.3 foundation and focuses on more capable workspace operations and a smoother daily workflow:
-**Keybinding Management**: View and edit common shortcuts from the settings UI with conflict hints.
-**Settings Page Polish**: A more compact and clearer settings experience with improved layout and interaction flow.
-**Multi-Pane Tabs with a tmux-like Workflow**: A single tab can now host multiple panes, with split, focus, and switching actions for a tmux-inspired experience.
-**Transfer History Improvements**: The transfer history panel now presents richer task details, making upload and download activity easier to review.
-**SSH Passphrase Support**: Private keys can now store a passphrase, and SSH connections will use it automatically.
-**Terminal Rendering Enhancements**: Terminal rendering now handles Block Elements and similar custom glyphs more completely.
## Download
You can download the latest installers from the [GitHub Releases page](https://github.com/rust-kotlin/ashell/releases/latest):
- macOS: `.dmg` installers for x64 and arm64, plus portable `.zip` archives.
- Windows: `Setup.exe` installers for x64, x86, and arm64, plus portable `.zip` archives.
- Linux: a portable x64 `.tar.gz` archive.
## Mac Installation Guide
### Method 1: Homebrew (Recommended)
If you use [Homebrew](https://brew.sh/), you can install it quickly with:
```bash
brew install rust-kotlin/taps/ashell --cask
```
To update the app:
```bash
brew update
brew upgrade ashell --cask
```
> **Note**: Since the app uses ad-hoc signing, the Homebrew installation or update includes a postflight script to automatically handle the quarantine flag. This will require you to enter your administrator password for authorization.
### Method 2: Manual Download
1. Download the `.dmg` matching your processor from the [Releases page](https://github.com/rust-kotlin/ashell/releases/latest).
2. Open the DMG and drag `ashell.app` into **Applications**.
3. Since the app uses ad-hoc signing, macOS may warn that the app is "damaged" upon first launch. If this happens, open Terminal and run:
```bash
sudo xattr -cr /Applications/ashell.app
```
## Windows Installation Guide
Download the appropriate installer from the [Releases page](https://github.com/rust-kotlin/ashell/releases/latest):
| System architecture | Installer suffix |
| --- | --- |
| Intel/AMD 64-bit | `windows-x64-setup.exe` |
| Intel/AMD 32-bit | `windows-x86-setup.exe` |
| Windows on ARM | `windows-arm64-setup.exe` |
The installer can optionally create a desktop shortcut and registers ashell in the Start menu and the Windows uninstall list.
The installer is not yet signed with a commercial code-signing certificate, so Windows SmartScreen may display a security warning.
## Features
The current version provides a fully-featured GPUI-native workspace:
- **Local & Remote Sessions:** Open local terminal tabs or connect to remote servers via SSH.
- **Advanced SSH Authentication:** Supports both password-based and key-based (file path or inline) SSH connections.
- **Session Management:** Easily save, reopen, edit, and remove your SSH sessions.
- **SFTP Integration:** Built-in SFTP file manager to browse, upload, download, and manage remote files.
- **Robust Terminal Emulator:** Parses terminal output with `alacritty_terminal`, supporting rich ANSI color spans, fast rendering, and complete keyboard input forwarding.
- **System Telemetry:** Real-time visualization of CPU, memory, swap, network, and disk metrics in the left cockpit sidebar.
- **Theming System:** Switch between multiple GPUI Component themes directly from the top toolbar.
- **Embedded Fonts:** Uses embedded Maple Mono NF CN fonts out-of-the-box for excellent CJK character and Nerd Font icon support.
- **v0.3 Core Enhancements:** Global font and font-size controls, concurrent SFTP transfers, persistent layout state, disconnect awareness, hot-swappable i18n, and smart terminal right-click copy/paste.
## Run
To run the application locally:
```bash
cargo run --release
```
## Codex and Terminal Completion Notifications
ashell supports generic OSC 9 completion notifications. For Codex CLI, add the following to
`~/.codex/config.toml`:
```toml
[tui]
notifications = ["agent-turn-complete", "approval-requested"]
notification_method = "osc9"
notification_condition = "unfocused"
```
When an eligible notification originates in the background or a non-visible tab, ashell shows a
native notification and a flashing bell on the corresponding tab. Unread notifications also add a
red badge to the macOS Dock icon or a red overlay to the Windows taskbar icon. Clicking the native
notification activates ashell and switches to the originating terminal tab; viewing that tab clears
its unread state. No reminder is shown when ashell is active and the notification originates in the
currently visible tab. An unselected tab shows a loading indicator beside its title for two seconds
after receiving terminal output. Continued output refreshes the indicator, while the selected tab
does not show it.
You can test a generic OSC 9 notification with:
```bash
printf '\033]9;Task completed\007'
```
## Package macOS App
```bash
./scripts/package-macos-app.sh
open target/release/ashell.app
```
The packaging script creates a standard `.app` bundle. It does not attach an entitlements file, and after signing, it verifies that `com.apple.security.app-sandbox` is not present (meaning it runs non-sandboxed).
## Package Linux (Debian/Ubuntu)
### Prerequisites
```bash
sudo apt install pkg-config libfontconfig1-dev
cargo install cargo-deb
```
### Build .deb
```bash
cargo build --release
cargo deb
```
The `.deb` file will be generated at:
```
target/debian/ashell_0.4.8-1_amd64.deb
```
### Install
```bash
sudo dpkg -i target/debian/ashell_0.4.8-1_amd64.deb
```
After installation, you can launch from the application menu or by running `ashell` in the terminal. The `.deb` package includes:
- `/usr/bin/ashell` — Main binary
- `/usr/share/applications/ashell.desktop` — Desktop entry
- `/usr/share/icons/hicolor/256x256/apps/ashell.png` — Application icon
