Remove Zend\I18n\View\Helper\AbstractTranslatorHelper dependency

[michalbundyra]

This is a follow-on from #32.

You cannot use the view helpers without requiring zend-view. This is because Zend\Form\View\Helper\AbstractHelper extends Zend\I18n\View\Helper\AbstractTranslatorHelper, which in turn extends Zend\View\Helper\AbstractHelper.

I would like to break this dependency. After a quick scan it looks like implementing the setView() / getView() / setTranslator() / getTranslator() methods in the abstract helper would do the trick. Would this be the right approach?

Unfortunately, it won't. AbstractHelper also implements HelperInterface, which all helpers need to implement. So while you'd remove the need to extend the base helper from zend-view, you'd still have the dependency due to the interface.

Gack :|

OK, so how about moving the core functionality to Zend\Form\Helper or similar and have Zend\Form\View\Helper\* proxy the core helpers?

That should be possible without a BC break (me, eternal optimist ;) and could provide a path towards moving them over to zend-view in future (discoverability / fewer suggests, as discussed over at https://github.com/zendframework/zend-validator/issues/1).

@kynx II like the idea that you have exposed in https://github.com/zendframework/zend-form/issues/32. i.e having a separate package for the view helpers dependent on zend-form and zend-view. kind regards

I'm a newbie and this just bit me for a few minutes with a 26-level stack trace. Figured it out eventually, but should zendframework/zend-i18n be a composer dependency of zendframework/zend-form so that it gets brought in, until this issue is figured out by the big brains?

@bitwombat

It is already there. See composer.json:

"suggest": {
    "zendframework/zend-i18n": "^2.6, required when using zend-form view helpers",
}

https://github.com/zendframework/zend-form/blob/master/composer.json#L46

Why suggest section in composer? Not everyone uses the view / output part of zend-form.

Ah, got it. So I should have read the 'suggested' output from composer better.

Thanks for the reply.

I am closing it. As stated, there is i18n component in suggest in composer.json

[froschdesign]

@samsonasik Please have a look at the original description of this issue report because the problem is not the Composer configuration.

[samsonasik]

@froschdesign ok, I re-open it.
