/*
Generates locales/<component>-msgs.js for each component (gui, etc) from the
current translation files for each language for that component
Translation files are expected to be in Chrome i18n json format:
'''
{
"message.id": {
"message": "The translated text",
"description": "Tips for translators"
},
...
}
'''
They are named by locale, for example: 'fr.json' or 'zh-cn.json'
Converts the collection of translation files to a single set of messages.
Example output:
'''
{
"en": {
"action.addBackdrop": "Add Backdrop",
"action.addCostume": "Add Costume",
"action.recordSound": "Record Sound",
"action.addSound": "Add Sound"
},
"fr": {
"action.addSound": "Ajouter Son",
"action.addCostume": "Ajouter Costume",
"action.addBackdrop": "Ajouter Arrière-plan",
"action.recordSound": "Enregistrement du Son"
}
}
'''
NOTE: blocks messages are plain key-value JSON files
Missing locales are ignored, react-intl will use the default messages for them.
