withfig/autocomplete

Fig makes the command line easier for individuals and more collaborative for teams.

Our most popular product is Autocomplete. As you type, Fig pops up subcommands, options, and contextually relevant arguments in your existing terminal.

• macOS:
  • DMG: Download from our website: fig.io
  • Homebrew: brew install fig
• Windows/Linux:
  • Join the waitlist
• Remote machines
  • Autocomplete in SSH
  • Autocomplete in Docker Containers

NOTE: Once it's downloaded, launch the app to set up Fig!

A completion spec is a declarative schema that specifies the subcommands, options and args for a CLI tool. Fig uses these schemas to generate suggestions.

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

Prerequisites:

• Download Fig for macOS
• Node and Pnpm

Steps

1. Make sure you have pnpm installed, as that's the package manager used in this repo.

2. Click here to fork this repo.

3. 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
   pnpm install
   
   # Create an example spec (call it "abc")
   pnpm create-spec abc
   
   # Turn on "dev mode"
   pnpm dev

4. Now go to your terminal and type abc[space]. Your example spec will appear. 😊

• 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 folder, and generators run every keystroke.

You can use Fig's autocomplete for your own tools too. Here's how to create private completions:

import { ai } from "@fig/autocomplete-generators"

...

generators: [
  ai({
    // the prompt
    prompt: "Generate a git commit message",
    
    // Send any relevant local context.
    message: async ({ executeShellCommand }) => {
      return executeShellCommand("git diff")
    },
    
    // turn each newline into a suggestion (can specify instead a `postProcess1 function if more flexibility is required)
    splitOn: "\n",
  })
]

# Typecheck all specs in the src/ folder
pnpm test

# Compile typescripts specs from src/ folder to build/ folder
pnpm build

# Lint and fix issues
pnpm lint:fix

We would love contributions for:

• new completion specs
• errors with existing completion specs (e.g. missing subcommands, 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.

Fig works with the native macOS Terminal app, iTerm, Tabby, Hyper, Kitty, WezTerm, and Alacritty. It also works in the integrated terminals of VSCode, JetBrains IDEs, Android Studio, and Nova.

Want to see another terminal included? Check our issue tracker and add your support for it!

Fig uses the Accessibility API on Mac to position the window, and integrates with your shell to read what you've typed.

Not yet, Fig is only available on macOS for now. Windows and Linux support is in progress!

Run brew install fig or, downloading the app at fig.io/download. Then, launch the Fig app!

Yes! Check out our guide on how to get started building autocomplete specs.

Check out our How to Contribute guide. Many of Fig's 200+ contributors made their first open source contribution to Fig!
