Ability to reuse commands between hooks and tasks

[silvenon]

I have a validate task that lints, checks types etc., and I'd like to reuse that in my pre-push hook as well, but I have to settle for:

validate:
  commands:
    # validation commands

pre-push:
  commands:
    validate: npx lefthook run validate

which doesn't provide a command-by-command experience that I would have seen if I had written each command individually. What I'm looking for is something like this:

validate:
  commands:
    # validation commands

pre-push:
  extends: validate
  commands:
    typescript: null # disable type checking on pre-push because it's slow

This way lefthook can copy over the entire configuration, and I can also run it in npm run validate if I wanted to etc.

You can use YAML anchors for this purpose:

• Re-use commands and scripts between hooks #470
• How can I generate configs for multiple directories? #633 (reply in thread)

Or you can explicitly call custom hooks:

# lefthook.yml

validate:
  commands:
    # ...

pre-push:
  commands:
    validate:
      run: lefthook run validate

Thanks! I was wondering what that was while I was searching around… I've never seen that syntax before 😄

Btw, the lefthook run validate experience isn't good because it will not show the progress of individual commands, it will only show the spinner for "validate" until all the commands are resolved.

That's why I was searching for an alternative.
