# User guide

Iris is a fast terminal autocomplete assistant written in Go. It wraps around your shell (Zsh, Bash, or Fish) to give you real-time command suggestions, a floating dropdown menu, and smart history search right where you type.

- OS: Linux or macOS
- Terminal emulator with ANSI color support
- Go 1.24 or newer (if building from source)

### Installation

### Shell setup

Add an alias to your shell configuration file to launch Iris easily:

```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"

```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`

```toml
[core]
version = 1
shell = ""        # "zsh", "bash", "fish", or empty for auto-detection
mode = "last"     # "last", "spec", or "history"
debug = false
expand-alias = true

[ui]
style = "modern"  # "modern" or "classic"
ghost-text = true
hidden-files = false
max-suggestions = 100
max-height = 15
nerd-fonts = true

[keybindings]
toggle-mode = "ctrl+r"
toggle-menu = "ctrl+space"

[git]
filter-active-branch = true
deduplicate-branches = true

[updater]
check-on-startup = true
channel = "stable" # "stable" or "nightly"
check-interval = "24h"

[ai]
enabled = false
provider = "groq" # "groq" or "ollama"
debounce_ms = 400

[ai.providers.groq]
endpoint = "https://api.groq.com/openai/v1/chat/completions"
api_key_env = "GROQ_API_KEY" # or set api_key directly
model = "llama-3.3-70b-versatile"
timeout_ms = 3000

[ai.providers.ollama]
endpoint = "http://localhost:11434/v1/chat/completions"
model = "qwen2.5-coder"
timeout_ms = 5000
```

> [!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**
