GoTo Velociraptor Check

So you thought no one would notice that one little goto you added? Watch out! This action is always watching, and will send velociraptors to anyone is foolish enough to try to sneak one in. Inspired by the xkcd comic goto:

Usage

You can use the action by adding this step to your project's workflow yaml:

name: Lint
on: [pull_request, push]
jobs:
    name: Goto Velociraptor Check
    steps:
      # Checking out the repo is NOT required
      # - uses: actions/checkout@v2
      - uses: NickCrews/gotoraptor@v1

If the action finds any gotos were added, then the PR or push commit gets flagged. The action looks through all added or modified lines in .cs, .c, .cpp,.h, and .hpp files, using a simple regex to find goto statements. This isn't perfect, and might result in some false positives and false negatives. A more complete method would be to actually compile the code and parse the syntax tree, but I found this not feasible: This action couldn't possibly know exactly how your project is compiled, what compiler flags are used, etc.

In the screenshot below you can see what the action does when it finds an added goto. Of note are the velociraptor memes, the xckd comic, and annotations on specific lines:
