Enhance lookup mechanics and priority propagation (`spec/lookup.go`) Remove the requirement of typing a leading `-` when searching for options, allowing flag suggestions to surface naturally during input Accurately forward the `Priority` field from registry specs into the `Suggestion` struct so the scoring engine evaluates relevance properly Integrate scoring into the main suggestion pipeline (`root/suggestions.go`) Collect context signals using `scoring.CollectSignals(cwd, query, rootCmd, store)` with the live working directory retrieved from `spec.GetCWD()` Pass the entire deduplicated list across spec, history and AI items through `scoring.Score(deduped, signals)` to compute scores and sort by descending order before rendering on screen Record execution history in Frecency Store (`root/wrapper.go`) Save the last executed command to `lastSubmittedCommand` whenever Enter is pressed or a suggestion is selected Trigger `store.Record(...)` asynchronously within the `IRIS_CMD_STOP` hook using a dedicated goroutine guarded by panic recovery and timeout limits, preventing blocks on the main shell thread Optimize workspace identification for AI (`internal/ai/context_provider.go`) Use `workspace.DetectCached(cwd)` to instantly fetch ecosystem context across Git, Node, Go, Rust, Python and Docker alongside active git branch state This caching mechanism avoids redundant subprocess execution when outside git repositories, significantly speeding up prompt context generation
IRIS (Intelligent Real-time Input Suggestion) - A shell auto-completion tool that works like code editor's IntelliSense
Comparison · Installation · Docs · Shortcuts · Reporting bugs
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 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 | < 15 MB | 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 |
Installation
curl -sSL https://raw.githubusercontent.com/versenilvis/iris/main/scripts/install.sh | sh
Warning
Currently, Windows is not supported
Theme
Note
Currently, IRIS doesn't have custom theme but it does have 2 basic styles
| Modern style | Classic style |

Shortcuts
| Shortcut | Action | Description |
|---|---|---|
| Shift + Tab | Toggle menu | Show or hide the suggestion menu. |
| Esc | Hide menu | Temporarily hide the menu until the next key press. |
| Tab | Accept suggestion | Insert the currently selected suggestion into the prompt. |
| Enter | Execute command | Close the menu and send the current command to the shell. |
| ↑ | Navigate up / history | Move the selection up, or open command history when the prompt is empty. |
| ↓ | Navigate down / history | Move the selection down, or open command history when the prompt is empty. |
| → | Accept ghost text | Accept the faded ghost text suggestion when the menu is open. |
| ← / → | Move cursor | Move the cursor inside the input buffer. Disabled when the prompt is empty. |
| Ctrl + R | Switch mode | Toggle between spec and history mode. |
| Ctrl + A | Beginning of line | Move the cursor to the start of the command line. |
| Ctrl + E | End of line | Move the cursor to the end of the command line. |
| Ctrl + L | Clear screen | Clear the terminal while preserving the input buffer and redrawing the menu. |
| Ctrl + U | Clear command | Remove the entire current command and close the menu. |
| Ctrl + C | Cancel command | Send SIGINT, clear the input buffer, and close the menu. |
| Ctrl + W | Delete word | Delete the word immediately before the cursor. |
Note
With Ctrl + A, Ctrl + E, Ctrl + W, Ctrl + U, Ctrl + L, and Ctrl + C: they belong to your shell by default. IRIS handles them directly in raw mode so your cursor and menu stay in sync
Reporting bugs
Note
Describing the bug you are facing, along with the relevant log
Enabling debug mode and then performing actions that led to the error
Run IRIS with debug mode:
iris -d
or config.toml:
debug=true
Important
Since IRIS logs everything you type, you should only enable debug mode when you need to report bugs
