Can mergify support pre/post hooks in their actions?

[v1v]

What

Do you think adding a pre/post hooks in the mergify actions could be something interesting to be enabled?

Why

Some of the users of mergify asked the below:

Would it be possible to tell mergify to run a custom script when backporting in order to fix the import paths?

Use case:

Given two branches with one of them changing some of the go import paths. I'd like to enable the backport with a pre-hook run to transform go paths from one way to another one.

Therefore, I'd like to configure mergify.yml with something like:

pull_request_rules:
  - name: backport patches to stable branch
    conditions:
      - base=main
      - label=backport-to-stable
    actions:
      backport:
        branches:
          - stable
        pre-hook: `scripts/transform.sh`

Where scripts/transform.sh transforms some paths in the code from the backport.

Rationale

This could be helpful to extend mergify with some more custom, though it might also require some contracts to avoid any security expose or timeout the script if it takes longer than xx seconds.

Hi!

Good point. This is not possible right now as you guessed, and I don't think it'll be possible short-term. Running custom scripts like this would have a great impact security-wise as you mentioned.

If we were to trigger something like this, it'd probably be via webhook or some other integration like GitHub Actions.

At this point, you're better off using GitHub Actions to achieve your complete workflow for this I think 😢
