Running target only when files (e.g from glob pattern) have changed

Hi

I am trying to achieve to do what github actions are doing with this configuration:

on:
  push:
    branches:
      - develop
    paths:
      - "docs/**/*"
  pull_request:
    branches:
      - develop
    paths:
      - "docs/**/*"

Meaning, that I want to run specific targets only when changes are detected.

Main goal is to avoid multiple build configurations (or workflow flies) in the repo.

Now there is one workflow which runs a nuke build pipeline, but ignoring changes in the docs subfolder, and an other workflow that runs a spell check target (from NUKE), but this workflow is only watching for changes inside the docs folder.

The two example workflows

Docs spell check

on:
  push:
    branches:
      - develop
    paths:
      - "docs/**/*"
  pull_request:
    branches:
      - develop
    paths:
      - "docs/**/*"
...

General build pipeline

on:
  pull_request:
    paths-ignore:
      - docs/**
  push:
    paths-ignore:
      - docs/**
...

I would put the "if" logic inside the Nuke target. That target would run every time but it could get Git changed files and based on that it could do the docs spell check or not. I am currently using the same approach for running unit test just for changed files.

Snippet:

		using (var repo = new LibGit2Sharp.Repository(localGitFolder))
		{
			GetBranchesToCompare(repo, oldBranchName, out var newBranchLocal, out var oldBranchLocal);
			var paths = repo.Diff.Compare<LibGit2Sharp.TreeChanges>(oldBranchLocal.Tip.Tree, newBranchLocal.Tip.Tree)
					.Where(x => x.Exists)
					.Select(x => x.Path);
                        if(paths.Any(x=>x.StartsWith("docs")))
                        {
                            //Do spell check
                        }
