👋 Add a completion spec for a CLI tool

Want to add autocomplete to a CLI tool (or make changes to an existing autocomplete spec)? We welcome contributions!

Completion specs are defined in a declarative schema that specifies subcommands, options and arguments. Suggestions are generated from information in the spec or can be generated dynamically by running shell commands or reading local files.

For documentation and tutorials, visit fig.io/docs.

To request autocomplete for a CLI tool, open an issue.

😎 Get Started

Build your first spec in 3 min or less: fig.io/docs/getting-started


  • Early access to the Fig macOS app.

    If you don't have access yet, sign up for the waitlist and say you're interested in building completions!

  • 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. Otherwise they are read from ~/.fig/autocomplete

📦 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>

We would love contributions for

  • any other completion spec for CLI tools you use regularly
  • generators for existing specs
