Deno support for githooks

See https://git-scm.com/docs/githooks and https://deno.land/manual@v1.25.4/tools/task_runner

This is a simple tool for deno projects that allows you to associate specific deno tasks with specific githooks by extending the native deno.json configuration file.

It works like this:

  • In your deno.json file, add a githooks key containing a map of {githook} to {deno task}. For example:
// deno.json
{
  "tasks": {
    "start": "deno run -A dev.ts",
    "check": "deno fmt --check && deno lint"
  },
  "githooks": {
    "pre-commit": "check"
  }
}
  • In your terminal, run the githooks.ts script. It will automatically create a hook file for each githook in your deno.json file.
$ deno run -A -r https://deno.land/x/githooks/githooks.ts

That's it. Now your git should call deno task check before every commit.

PROTIP: deco Live projects come with this extension pre-installed in the dev script. You don't have to do anything, just add githooks to deno.json and run dev to install the hooks transparently.
