**IRIS is built on top of TTY, so it runs everywhere. It just needs a terminal!**
|
|
|
|
Run iris wherever you already work; your local machine, a remote server, or anywhere you can ssh. Each suggestion menu renders directly inline inside your real terminal session, not an app's imitation of one, so it never breaks full-screen TUIs or terminal formatting. Automatically index your aliases and shell history to suggest commands that match your actual workflow in real time. Change configurations and propagate them instantly without restarting your shell. One single local native Go binary, not an app: no gui, no electron, no mac-only wrapper, no account, no telemetry. (if you've used fig: it's that, rebuilt to run purely on TTY)

## Why IRIS instead of Fig
|
|
|
|
> [!IMPORTANT]
|
|
> **[Fig](https://app.fig.io/) was officially sunset in September 2024 and migrated to Amazon Q Developer (which requires cloud authentication and proprietary bloat)**
|
|
> **IRIS is the lightweight, open-source, zero-telemetry alternative built purely on native Go and TTY with no accounts, no GUI app, and no background daemons required**
|
|
|
|
### How it compares
|
|
|
|
| Feature | IRIS | Fig |
|
|
| :-------------------------- | :------------------- | :--------------- |
|
|
| **Platforms** | Linux, macOS | macOS only |
|
|
| **Engine** | Native Go (TTY) | Electron |
|
|
| **Startup** | Near-zero overhead | Low overhead |
|
|
| **UI** | Inline overlay | GUI popover |
|
|
| **Remote SSH** | TTY-native, portable | macOS GUI-bound |
|
|
| **Tmux** | ✓ | Limited |
|
|
| **Linux virtual terminals** | ✓ | - |
|
|
| **Memory** | Lightweight | Electron runtime |
|
|
|
|
## Why not shell autocomplete plugins?
|
|
|
|
Shell plugins are great, but they also come with trade-offs. And also, not everyone use Zsh or Fish especially on SSH.
|
|
|
|
| Feature | IRIS | Shell plugins |
|
|
| :-------------------------- | :---------------------- | :--------------------------- |
|
|
| **Installation** | Single binary | Plugin manager required |
|
|
| **Shell support** | Most shells supported | Usually shell-specific |
|
|
| **Startup** | No shell initialization | Increases shell startup time |
|
|
| **SSH** | One config | Per-shell config |
|
|
| **Tmux** | ✓ | Depends on the shell |
|
|
| **Linux virtual terminals** | ✓ | Depends on the shell |
|
|
|
|

|
|
|
|

|
|

|
|
|
|
#### Method 1: Package managers
|
|
|
|
<details>
|
|
<summary><b>Arch Linux (AUR)</b></summary>
|
|
<br>
|
|
|
|
IRIS is available on the Arch User Repository. You can install it using your favorite AUR helper:
|
|
|
|
```bash
|
|
yay -S iris-autocomplete
|
|
```
|
|
|
|
OR
|
|
|
|
```bash
|
|
paru -S iris-autocomplete
|
|
```
|
|
</details>
|
|
|
|
<details>
|
|
<summary><b>macOS / Linux (Homebrew)</b></summary>
|
|
<br>
|
|
|
|
Install IRIS via Homebrew tap:
|
|
|
|
```bash
|
|
brew install versenilvis/iris/iris
|
|
```
|
|
</details>
|
|
|
|
<details>
|
|
<summary><b>Nix Flakes</b></summary>
|
|
<br>
|
|
|
|
If you are using Nix Flakes, you can consume this module directly without building it manually.
|
|
|
|
1. In your `flake.nix` inputs, add:
|
|
|
|
```nix
|
|
iris.url = "github:versenilvis/iris/main";
|
|
```
|
|
|
|
2. Then, use one of the following options to add IRIS to your system:
|
|
|
|
**Option A: Try without installing (ephemeral)**
|
|
```bash
|
|
nix run github:versenilvis/iris
|
|
```
|
|
|
|
**Option B: Install to your user profile**
|
|
```bash
|
|
nix profile install github:versenilvis/iris
|
|
```
|
|
|
|
**Option C: Using Home Manager**
|
|
*(Ensure you pass `inputs` to modules via `extraSpecialArgs`)*
|
|
```nix
|
|
home.packages = [ inputs.iris.packages.${pkgs.system}.default ];
|
|
```
|
|
|
|
**Option D: Without Home Manager (NixOS System)**
|
|
*(Ensure you pass `inputs` to modules via `specialArgs`)*
|
|
```nix
|
|
environment.systemPackages = [ inputs.iris.packages.${pkgs.system}.default ];
|
|
```
|
|

|
|
sudo dpkg -i iris_linux_amd64.deb
|
|
rm iris_linux_amd64.deb

|
|
If you use [aqua](https://aquaproj.github.io/), you can install IRIS by adding it to your `aqua.yaml`:
|
|
|
|
```yaml
|
|
packages:
|
|
- name: versenilvis/iris
|
|
```
|
|
|
|
Then run `aqua i`.

|
<details>
|
|
<summary><b>asdf</b></summary>
|
|
<br>
|
|
|
|
If you use [asdf](https://asdf-vm.com/), you can install IRIS via its plugin:
|
|
|
|
```bash
|
|
asdf plugin add iris https://github.com/versenilvis/asdf-iris.git
|
|
asdf install iris latest
|
|
asdf set -u iris latest
|
|
asdf current iris
|
|
```
|
|
</details>
|
|
|
|
#### Method 2: Install script (recommended)
|
|
|
|
```bash
|
|
curl -sSL https://raw.githubusercontent.com/versenilvis/iris/main/scripts/install.sh | sh
|
|
```
|
|
|
|
#### Method 3: Go install
|
|
|
|
```bash
|
|
go install github.com/versenilvis/iris/cmd/iris@latest
|
|
```
|
|
|
|
#### Method 4: Build from source (for developers)
|
|
|
|
```bash
|
|
git clone https://github.com/versenilvis/iris.git
|
|
cd iris
|
|
just reload
|
|
```
|
|
|
|
## Uninstall
|
|
|
|
To completely uninstall IRIS, remove all configurations, and clean up your shell integration files, simply run:
|
|
|
|
```bash
|
|
iris uninstall
|
|
```
|
|
|
|
## Shell setup
|
|
|
|
> [!WARNING]
|
|
> **IRIS may cause visual conflicts and keybinding overlaps with other shell autosuggestion plugins or third-party completion tools. To prevent this, please disable them safely (e.g., zsh-autosuggestions, zsh-autocomplete, atuin, flyline, ...)**
|
|
|
|
Add an alias to your shell configuration file to launch IRIS easily:
|
|
|
|
**Zsh (`~/.zshrc`):**
|
|
```zsh
|
|
if command -v iris >/dev/null 2>&1; then
|
|
alias i="iris"
|
|
fi
|
|
```
|
|
|
|
**Bash (`~/.bashrc`):**
|
|
```bash
|
|
if command -v iris >/dev/null 2>&1; then
|
|
alias i="iris"
|
|
fi
|
|
```
|
|
|
|
**Fish (`~/.config/fish/config.fish`):**
|
|
```fish
|
|
if command -v iris >/dev/null 2>&1
|
|
alias i="iris"
|
|
end
|
|
```
|
|
## Configuration guide
|
|
|
|
IRIS uses a clean TOML configuration file located at `~/.config/iris/config.toml`.
|
|
|
|
### Creating & viewing config
|
|
|
|
```bash
|
|
iris config init
|
|
iris config show
|
|
```
|
|
|
|
### Sample `config.toml`

|
|
```
|
|
|
|
> [!NOTE]
|
|
> Using `api_key_env` is recommended over hardcoding `api_key` in plain text to keep credentials out of configuration files.

## Reporting bugs
|
|
> [!NOTE]
|
|
> When submitting a bug report, please include:
|
|
> - A detailed description of the bug and steps to reproduce it
|
|
> - Relevant log files captured while running in debug mode
|
|
|
|
Run IRIS with debug mode:
|
|
```bash
|
|
iris -d
|
|
```
|
|
or `config.toml`:
|
|
```toml
|
|
debug=true
|
|
```
|
|
|
|
> [!IMPORTANT]
|
|
> **Since IRIS logs everything you type, you should only enable debug mode when you need to report bugs**
|
|
|
|
If IRIS crashes, it will automatically save a crash log and show the path on your terminal (`~/.iris/crash.log`). Or you can find the path to the latest crash log by running:
|
|
```bash
|
|
iris crash-log
|
|
```
|
|
Please include this file when reporting a crash.
