Translation file placeholder

[Renato66]

I have an existing project and im start to implement i18n, but its a little hard to me to see every text that needs to be transformed into $t in my app and we don't have any translations yet making it impossible to the QA team test. Then i made this simple file that put a emoji ✅ in front of every word/phrase based on a 'complete' translation file

// lang/en.js
import ptBr from '../pt-BR' // my  'complete' translation file
export default JSON.parse(JSON.stringify(ptBr).replace(/":"/g, '":"✅ ').replace(/\|/g, '| ✅ '))

this file could be in the docs, or in the files that the plugin changes

I am sorry but I do noy understand what is your problem and what improvements you expect in vue-i18n.
Could you add more detail?

[Renato66]

when you don't have a translation file in other language, its hard to test if every text is in $t() format
with this you could easily see, where you are missing the $t() because that text wont have a placeholder like ✅ in front of the text

here im missing Area Chart Example to be transformed in $t()

OK, I understood your technique to distinguish translated/non-translated strings visually by adding icons.

BTW, if fallback translation showed, a meesage like "Fall back to translate the keypath 'hello' with 'en-US' locale." will be displayed in the console.

The technique sounds useful for QA, but I think it should not be enabled by default in vue-i18n itself, since such icons should not be displayed in the app in production,.
SGTM to document the technique as TIPS in the docs. Contributions are welcome !!

To distinguish translated/non-translated strings visually (not only log in console), I will propose "FallbackHandler" that allows changing strings in case of fallback, so we may add icon (❌ or 🔥 ) to the fallback locale strings.
Currently, there is MissingHandler that allows changing string only in ase of key missing.
WDYT?

I still don't have that file, we are just preparing the soil to receive that translation

Yah that sounds great ( the 🔥 is better)

it could have a function in VueI18n constructor that grabs the message object and transforms it

export const i18n = new VueI18n({
  locale: 'pt-BR', // set locale
  fallbackLocale: 'pt-BR',
  showIcons: false, // process.env.NODE_ENV !== 'production' default: false
  messages: {
    'pt-BR': ptBR
  }
})

Thank you for your feature request!
This feature is very interesting!

However, we need to verify a little more whether this feature breaks other features (e.g. linked messages, Component interpolation, ... etc), due to this feature change locale messages.

export default JSON.parse(JSON.stringify(ptBr).replace(/":"/g, '":"✅ ').replace(/|/g, '| ✅ '))

In particular, this should be handled a little more strictly.

@kazupon this feature attends "just" my project, but this pr #732 have some options to toggle and has some tests to make sure that nothing breaks the code =)
