Feature : Configuration with babel config (.babelrc, ...)

Would it be possible to configure macros directly with the babel config (.babelrc or other babel config) :

// .babelrc
{
  "plugins": ["macros", {
    "taggedTranslations": { 
      "someConfig": {}
    }
  }]
}

Then you get it like this in the macro :

const { createMacro } = require('babel-plugin-macros')

const configName = 'taggedTranslations'

module.exports = createMacro(taggedTranslationsMacro, { configName })

function taggedTranslationsMacro({references, state, babel, config}) {
  // config is { someConfig: {} }
}

This way, it’s easier to test a specific config :

import pluginTester from 'babel-plugin-tester'
import plugin from 'babel-plugin-macros'

pluginTester({
  plugin,
  snapshot: true,
  babelOptions: { filename: __filename },
  tests: [{
    code: `...`,
    babelOptions: {
      taggedTranslations: { someConfigIWantToTest: {} } // i add my config here 🚀
    }
  }],
})

@kentcdodds That’s all I need, thanks !

I think you should be able to test this by mocking cosmiconfig like we do in our tests: https://github.com/kentcdodds/babel-plugin-macros/blob/1785a0fab2c374d1505c49cff1bd38fd541819e2/src/__tests__/index.js#L255-L306

I don’t want to have two ways to do the same thing and I’m still not convinced that config is a good thing for macros anyway.

In any case, I don’t think we’ll be doing anything with this issue (unless you’d like to document an example of how to test this situation). Thanks!
