Integration with Vue

[WaltzingPenguin]

I'm attempting to integrate ttag with Vue's single file components.

<template>
    <p>{{ gettext('foo-template') }}</p>
</template>

<script>
import { gettext } from 'ttag'

export default {
    data() {
        return {
            text: gettext('foo-script')
        }
    },
    methods: {
        gettext
    }
}
</script>

foo-script gets picked up and translated just fine, but nothing inside of the <template> tag does. Looking through the compiled output, {{ gettext('foo-template') }} gets compiled into this.gettext('foo-template') and ttag currently does not handle its functions being reassigned.

Is there any way to get babel-plugin-ttl to recognize this.gettext as a target? The discover option doesn't seem to work once a "." is invovled.

This is also an issue when integrating with Svelte, so I'm assuming there's a fair number frameworks with similar issues.

Edit: The library works just fine with Svelte, without modifications. Functions just need to be passed down to the template through "helpers"

Hello @ADantes! Unfortunately, I have not tried ttag with Vue. Currently this.gettext will be not recognized by babel-plugin-ttag. Going to investigate this issue, and will report any progress on Vue and Svelte here ASAP.

It would be really helpful if you could set up some example repository with just basic Vue and ttag.

Thank you for taking a look into this! This is the example I was trying: https://github.com/ADantes/ttag-with-vue

If you run npx webpack, the output template.po file contains only one of the two items I'm looking for.

For an even simpler case, I believe a solution for this would solve the same problem:

import { gettext } from 'ttag'

export function View() {
    this.gettext = gettext
}
View.prototype.render = function render() {
    return this.gettext('foo-render')
}

As far as I can see, we should implement this as a plugin for Vue - https://vuejs.org/v2/guide/plugins.html#Writing-a-Plugin to have gettext available in a templates. gettext func is good for simple strings translations. But what about formatting? As I understood we can not just simply use template literals like

t`Hello ${ name }`

inside Vue templates.
But, I think we can just start with a simple gettext('translation') and later add formatting options. But, would it be enough? How do you think @ADantes ?

This seems helpful vuejs/vue#9721 (comment)

So it is quite trivial to add tagged template support and write a plugin to expose the functions, but the problem remains that babel-plugin-ttag doesn't recognize something.t. @AlexMost what can we do about this? Maybe make the matching configurable?

Hi @graup! Thanks for the helpful link, will try to investigate. Also, any help will be appreciated!
