Using Dotenv in yaml config does not provide value of env var

A new issue to try and resolve my question in the final comment of #1040 as it's likely an unrelated issue.

As per your suggestion in https://github.com/phpro/grumphp/issues/1040#issuecomment-1228604767 I am trying to inject the value of an environment variable into the GrumPHP yaml configuration file.

I have encountered a strange issue trying to get this setup. Instead of making the actual value of my GITLAB_TOKEN env var available, I get a strange string which looks like env_e7937a168f382d27_GITLAB_TOKEN_4e06944bcec1f665r4a82bf0125e3f8d.

# .env.local

GITLAB_TOKEN=XXXXXX

# grumphp.yml

grumphp:
    tasks:
        gitlab_lint:
            api_token: '%env(GITLAB_TOKEN)%'
    environment:
        files:
            - .env.local

Any pointers much appreciated. Thank you.

Hello @benr77,

Took some time to like into the issue - but haven't found a solution yet. There are 2 issues:

1. The env vars from your grumphp config are registered in grumPHP AFTER the container has been built. See https://github.com/phpro/grumphp/blob/f482be4a872078d0e3c0a50a8968976eba4b6bd6/src/Configuration/ContainerFactory.php#L28-L35

2. Even if I tried registering them before - I get the placeholder. Symfony dependency-injection discovers that we want to use a ENV var: https://github.com/symfony/dependency-injection/blob/b9c797c9d56afc290d4265854bafd01b4e379240/ParameterBag/EnvPlaceholderParameterBag.php#L72 Yet it fails to resolve that - even though the https://github.com/symfony/dependency-injection/blob/6.1/Compiler/RegisterEnvVarProcessorsPass.php goes over it. It seems like the container does not provide any container.env_var_processor by default. Meaning the env var doesn't get resolved into it's corresponding value.

The first issue might something we need to change in our configuration. The second one: I'm not sure.... Maybe you can open up a ticket in symfony to ask what the recommended way is for processing .env vars outside the framework (inside a new container)?

Care to take a further look at this? I currently lack some time ...

Maybe an easier way to test this ;)

HELLO=WORLD

grumphp:
  tasks:
    git_commit_message:
      matchers:
        env matcher: "/%env(string:HELLO)%-\\d+/"
  environment:
    files:
      - .env.local

Thanks for taking the time to look into this.

I have opened a discussion on Symfony to try and get a solution. https://github.com/symfony/symfony/discussions/47771

Unfortunately I have not been able to find out any more information from the Symfony community about this.

Then the only way forward is figuring out what is going on in symfony ... It's probably something small or stupid that needs to be activated

@benr77 It should be fixed with #1113.
