Yet another attribute translation question

[anilanar]

I looked through issues here and I couldn't find one that mentions this problem. Currently it's impossible to translate the following without translating strings in JS:

<input placeholder="Numbers between {{start}} and {{end}}">

Feature request:

Support one of the following syntaxes:

<input translate-placeholder placeholder="Numbers between {{start}} and {{end}}">

or

<input translate-attr="placeholder" placeholder="Numbers between {{start}} and {{end}}">

With this approach, translate-plural, translate-n, translate-context and any other directive related mechanisms can be used for attributes.

Related to #226.

<input placeholder="'Numbers between {{start}} and {{end}}'|translate">

Right. I see your issue. You could pipe it to another filter to do interpolation. Something like:

app.filter('substitute', function($interpolate) {
return function(text, context) {
    var interpolateFn = $interpolate(text);
    return interpolateFn(context);
}
});

<input placeholder="'Numbers between {{start}} and {{end}}'|translate|substitute:{start: '1', end: '30'}">

How's this for a workaround: http://plnkr.co/edit/5vdiC8Nydm351BtPzap9?p=preview

👍 This is a much needed feature IMO...

Much needed feature indeed. Just moving a project from angular-translate to angular-gettext and did not have those issues there. You could simple do:

{{ 'This is {{var1}} favourite {{var2}}.' | translate : { var1: 'my', var2: 'place' } }}

Which would translate into:

This is my favourite place

I understand that due to the minimalistic footprint you do not want to add this feature, but the substitute filter is a ridiculous (though: working!) workaround, that does not feel like it should be used like that. Particularly when translators are presented with using [[]] some times, and `{{}}`` other times.

Would be great if it would find its way into the library.

Finally, @anilanar, I see you live in Germany, so: "Der Ton macht die Musik" (= It's not what you say, but how you say it.).

Stumbled upon this today: https://angular-gettext.rocketeer.be/dev-guide/custom-annotations/
You can just create a new directive called "placeholder" which will run all placeholders through translation automatically.

@intellix that example doesn't support interpolation. You can duplicate everything in the translate directive logic, but I'm guessing that @anilanar doesn't want to do that.
