Accumulating scripts to avoid running multiple times

[brettz9]

This request can probably be best explained with an example.

{
    "src": "npm test && npm run build && npm run check-readme",
    "test": "npm test && npm run create-readme",
}

...I don't want to re-run test if both src and test files are modified.

Is there a way it could be recognized such that npm test wouldn't need to be repeated?

@brettz9 Hi! Sorry for the late reply, but with the more recent changes this is now possible.

You can configure it using arrays like this:

{
    "src": ["npm test", "npm run build", "npm run check-readme"],
    "test": ["npm test", "npm run create-readme"],
}

The whole hook would fail if any of the commands return a non-zero exit code and would stop further execution.
The commands would be run in order, but only once regardless of how many file patterns matched which caused them to run.

If you change both src and test in one Git operation, run-if-changed would run:

npm test
npm run build
npm run check-readme
