A logic to trigger tasks with extensionless files

[eandersons]

There may be cases when extensionless files have to be checked by specific tasks, but I did not manage find how to get the files without extension to trigger tasks.

A couple of use cases with extensionless files:

• the directory bin/ is expected all files to be shell scripts, and they should be checked with shell task (for example, with shellcheck);
• the directory app/bin/ is expected to have PHP executables that should be checked as PHP files;
• Dockerfiles also have linting tools,

, so it would be quite safe to assume that files in specific directories or with specific name are of certain type.

Can tasks be triggered by extensionless files with the current functionality?

If not, probably a new option (triggered_by_globs or triggered_by_patterns) which would accept values like bin/*, app/bin/* or Dockerfile could be added, but I am not sure how well that would fit with the current implementation of file filtering.

A possible workaround is to add extension to all those files, but there are cases when executable files have to be extensionless (for example, the task doctrine_orm expects the executable file doctrine to be found). A workaround to that would be to create a symbolic link (for example: ln -s doctrine.php doctrine).
I would rather not use such workarounds, but it does not seem that currently I have other options.

The answer depends from task to task: Depending on what options are available, this is already possible.

You can choose not to provide triggered_by which will accept all, and use whitelist_patterns to specify the filenames or even globs.
Again, this depends on the possibilities of the task(s) you try to execute.

Would not by not specifying triggered_by the defaults be used? I am looking at tasks phpstan and shell, and both have php as default.
I also tried a shell task with whitespace_patterns and without triggered_by with the same outcome - a skipped task. I tried also triggered_by: [], still nothing.

Configuration:

grumphp:
  environment:
    paths:
      - app/vendor/bin
  tasks:
    shellcheck:
      metadata:
        task: shell
      scripts:
        - bin/shellcheck
      triggered_by: []
      whitelist_patterns:
        - /bin\/doctrine/

Output:

app/vendor/bin/grumphp run --tasks shellcheck --verbose
[..]
[2025-09-05T13:34:19.132858+00:00] GrumPHP.DEBUG: last command (ls-files) output: [..] bin/doctrine [..]  [] []
GrumPHP is sniffing your code!

Running task 1/1: shellcheck...

The issue seems to be here:

grumphp/src/Collection/FilesCollection.php

Lines 129 to 133 in 49baf65

	public function extensions(array $extensions): self
	{
	if (!\count($extensions)) {
	return new self();
	}

Once I change that line to return $this, it works as expected.
I'm not sure why it is returning an empty list of files when no extensions are provided instead of e.g. previous list anymore.
So I'm not sure it's a bug or desired behaviour.
