Add "Namespace" support

[jakejohns]

Zend Expressive Template Interface defines support for namespaces using the :: scope resolution operator.

• Plates calls this folders
• Twig has namespaces, but they have a weird @ notation.

Personally, I've just been using paths to basically simulate some approximation of this functionality, and had previously been considering trying to add some kind of PSR-4-like directory definition that would basically just pretend a directory structure was deeper than it was, but this seems like a solution, and seems to exist elsewhere too.

Thoughts?

(On an unrelated note, and thoughts/idea on starting 3.x anytime so we can modernize some syntax and get rid of some of the old cruft?)

I just noticed that @harikt has harikt/hkt-expressive-auraviewrenderer, but I'm not sure I understand totally how the namespace thing is implemented. It looks to me like it's just disregarded?

Hi @jakejohns ,

I am a bit sick, and have some trouble with eye. So this is quick reply. I may want to look more into what you need here.

Basically it was trying to work in the way expressive was doing.

https:/harikt/hkt-expressive-auraviewrenderer/blob/master/src/AuraViewRenderer.php#L90

addPath($path, $namespace = null)

So addPath('/templates/error', 'err') see here https:/harikt/hkt-expressive-auraviewrenderer/blob/master/src/AuraViewRendererFactory.php#L29-L41

Hey @jakejohns ,

Thanks for making the implementation. I think you have made the namespace in the core. My repo just create namespace on top of expressive renderer. Do you have any other questions ?

[harikt]

I have merged #80 . If you merge those changes the unit tests will pass on 7.x I believe.

[harikt]

Thank you.

This looks good to me.

@pmjones do you have any thoughts ? Else I can merge this and make a release.

[harikt]

Hey @jakejohns ,

can you add some documentation to this.

I will merge once you are done, do ping me so I don't miss it.

[jakejohns]

@harikt how's this?

[harikt]

This looks good.

Question : Do you think we can add a way to set the namespace separator ?

So it may help to change the delimiter from :: to something else also if needed. That may be a rare case though.

UPDATE : May be that will over kill the template registry. Lets not worry about that now 👍 .

Thank you @jakejohns .
