What about directive?

[Disorrder]

Please, make it useful like angular-translate. I mean, it's really good to use it by directive and filter

For example,

<span v-translate="error.{{authError}}"></span>

Renders into

<span>Unexpected username!</span>

Hi @Disorrder !!
Thank you for your comment.

The vue-i18n is inspired by Rails Internationalization API.
http://guides.rubyonrails.org/i18n.html

I think that current translation style is simple than better angular translate style.

Also, it's flexible as in the following code (e.g. inline, computed property and method).

I don't plan to add feature in future.

分かった :D
I've got used to angular syntax and now using Vue for extremely compact MVVM application, this code works fine.
(es6 & jade syntax)

Vue.directive('translate', {
    isLiteral: true,
    update(val) {
        this.el.innerHTML = this.vm.$t(val);
    }
})

span(v-if="error", v-translate="error.{{error}}")

Yes !
You can extend with custome directive. :)

@Disorrder this would have also worked:

<a :v-text="$t('error.' + error)"></a>
