How to allow Moderators to bypass Rules?

Aki-to

I've created the following extension for limiting a post's length to 700 characters.

https://packagist.org/packages/akito/flarum-limit-post-length#0.1.0

I would like to allow users with certain roles, like e.g. moderators, to bypass this rule.
I suppose, I would need to check against the role ID, whether the post should be limited or not.
However, I am not sure, which API to use in this case.

I would appreciate, if someone could point me to related places in here.

The recommended way to do this would be to use permissions.

You can add a permission to the admin side of things with this documentation and you can then check if a user has those permissions using this part of the documentation.

So you could create a permission called bypassLengthLimit and then assign that permission to admins and moderators (and any other group you'd want) and anyone without that permission would be restricted.

I see, thanks, that makes sense.

Would I add a similar code snippet to the extend.php of my extension or where would I put that, so Flarum understands it?

Snippet from Documentation

app.initializers.add('interstellar', function(app) {

  app.extensionData
    .for('acme-interstellar')
    .registerPermission(
      {
        icon: 'fas fa-rocket', // Font-Awesome Icon
        label: app.translator.trans('acme-interstellar.admin.permissions.fly_rockets_label'), // Permission Label
        permission: 'discussion.rocket_fly', // Actual permission name stored in database (and used when checking permission).
        tagScoped: true, // Whether it be possible to apply this permission on tags, not just globally. Explained in the next paragraph.
      }, 
      'start', // Category permission will be added to on the grid
      95 // Optional: Priority
    );
});

I now checked all the related documentation, looked at other extensions to get an idea by example, though I'm not sure how to implement this. Where exactly do I put the permission setting? Where & how exactly would I ask, whether the user has the permission? Wouldn't the post validator need access to the current User instance?

I would appreciate specific examples on how this would work in my extension.

Been trying to figure out how to implement this & it won't budge. All I want is a getActor in the configuration for new Extend\Validator(PostValidator::class), but it does not seem to be possible & I don't know how I would tell the validation to skip the character limit, when the callback is registered without an if telling it to skip on certain conditions.
