Getting started

Make sure you have Node v18+ installed.

The easiest way try out the CLI is using npx:

$ npx george-cli myfile.grg

The CLI can check multiple files at once:

$ npx george-cli *.grg

When used in combination with a clipboard tool like pbcopy or xclip, it becomes really easy to share the analysis of all your .grg files with your classmates:

$ npx george-cli *.grg | pbcopy # Copy to clipboard on Mac
$ npx george-cli *.grg | xclip -selection clipboard # Copy to clipboard on Linux, I'd recommend creating an alias

You can also watch for file changes to get feedback from George as you edit the file:

$ npx george-cli --watch *.grg

Recommended Workflow

For your SE212 assignments I recommend you save your work in a private git repository. You can create an npm project and install the CLI locally and make npm run test test all your .grg files. When editing files in an editor (e.g. VSCode), you make npm run watch script and run that in your editor's terminal while you edit your files.

$ npm init -y
$ touch a.grg, b.grg, c.grg # example 
$ npm install --save-dev george-cli
$ vim package.json # change the "test" script command to run george-cli
$ cat package.json

  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "npx george *.grg",
    "watch": "npx george --watch *.grg"
