Support for message key prefix

[fabiancz]

This feature simplify writing of translate keys in templates. Example of Nette template:

{block #content}
{translatePrefix 'messages.example.'}
    <h1>{_title}</h1>
    <h2>{_subtitle}</h2>
    <p>{_some_text}</p>
{/translatePrefix}
{/block}

messages.en_EN.neon file:

example:
    title: "Title of the page"
    subtitle: "Subtitle of the page"
    some_text: "Lorem ipsum sil dolor amet .."

You appreciate this, when you'r preparing large Nette templates for translation. Writing/copying same prefix of keys is really annoying.

Should nott be here $template instead of $presenter?

[fabiancz]

With $template it throws: "The variable 'translator' does not exist in template."

You'd have to add this variable somewhere in BasePresenter createTemplate():

$template->translator = $this->translator;

And I think this is unnecessary step.

Please, see changes - there is typo in indention. It must be fixed, thanks.

I think it's wrong to have this in the Translator class. However I do think it could be useful in templates. The macro {translatePrefix} could set the prefix in a local variable inside the template and then the macro {_} could prepend it automatically.

It certainly doesn't belong to translator and the indentation is horrible :)

Better would be to create a class PrefixedTranslator which would wrap existing translator and at the end of the macro it will then unwrap it.

Fyi there is an issue for this :) #3

Sorry for indentation. It works bad with my IDE.

I think it should be in Translator class (or PrefixedTranslator for example) because then you can use it both in PHP and template.

[fprochazka]

The problem with adding it directly to Translator class is a global state, which will be a problem, when you use the translator in presenters and forms.

Thank you for your time, would you mind testing the new macro? I'm also open to better naming if anyone has a thought. Please let any further discussion happen at #3
