Fig adds autocomplete to your terminal.

As you type, Fig pops up subcommands, options, and contextually relevant arguments in your existing terminal on macOS.

Fig Visual Autocomplete For Your Terminal Demo

⚡️ Installation

👋 What are "completion specs"?

A completion spec is a declarative schema that specifies the subcommands, options and arguments for a CLI tool. We use these schemas to generate suggestions.

😎 Contribute your first spec in < 3 minutes

Use the steps below or follow our getting started guide: fig.io/docs


  • Download Fig for macOS
  • Node and NPM (or Yarn).


  1. Click here to fork this repo.

  2. Clone your forked repo and create an example spec

# Replace `YOUR_GITHUB_USERNAME` with your own github username
git clone https://github.com/YOUR_GITHUB_USERNAME/autocomplete.git fig-autocomplete
cd fig-autocomplete

# Add withfig/autocomplete as a remote
git remote add upstream https://github.com/withfig/autocomplete.git

# Install packages
npm install

# Create an example spec (call it "abc")
npm run create-spec abc

# Turn on "dev mode"
npm run dev
  1. Now go to your terminal and type abc[space]. Your example spec will appear. 😊

Other things to know

  • Edit your spec in typescript in the src/ folder
  • On save, specs are compiled to the build/ folder
  • In dev mode specs are read from the build folders.

📦 Other available package.json commands

# Typecheck all specs in the src/ folder
npm test

# Compile typescripts specs from src/ folder to build/ folder
npm run build

# Copy all specs from the build/ folder to the ~/.fig/autocomplete folder
npm run copy:all

# Copy an individual spec from the build/ folder to the ~/.fig/autocomplete folder
npm run copy <spec-name>

🔥 Contributions

We would love contributions for:

  • new completion specs
  • errors with existing completion specs (e.g. missing subcomannds, options, or arguments)
  • generators for argument suggestions
  • better descriptions, icons etc
  • themes!

If you aren't able to contribute, please feel free to open an issue. Most people think that contributing will be too hard, but you'd be surprised, we have deliberately made contributing very very easy. Give it a go!
