Botbuilder如何在命名空间未定义的情况下使用默认语言环境字符串

Question

I am using the botbuilder framework. I have defined several namespaces for the dialogs I have created, such as help or default . For all of these I have also created json files in my locale/en/ directory, and all is well. However, I have a few sentences that are very common, and I don't feel like copying those over to each of the individual namespaces. I have tried using index.json as a 'fallback' in case the namespace file doesn't define the string. But it doesn't work for me. Contrary to what the documentation seems to suggest.

/locale
  /en
    /help.json
    /default.json
    /index.json <-- Doesn't work
/dialogs
  /help.js
  /default.js
bot.js

Say I have the following library in help.js , that :

lib = new builder.Library('help')
lib.dialog('/', (session) => {
  session.send('custom_cancel')
}
module.exports = lib

The library is used in bot.js :

bot.library(require('./dialogs/help'))

And index.json has this content:

{
  "custom_cancel": "My custom cancel"
}

Whereas help.json is empty:

 {}

Because help.json does not have custom_cancel , the bot will actually send custom_cancel as the string.

Again. I can copy paste the strings to both locations and there is no more problem. But that seems like an ugly solution to me.

Answer 1

I have tried the more explicit version, which seems to help in more cases, but I am not fully convinced yet.

session.localizer.gettext(session.preferredLocale(), 'custom_cancel')

You can use the third argument for the namespace. It seems that '' will point to the index.json file.
