Request: Support for dotenv-rails, to load GOOGLE_TRANSLATE_API_KEY from .env.development

[ndbroadbent]

Hello, I use the dotenv-rails gem to define configuration vars in .env, .env.test, .env.development, etc. This doesn't seem to be working with i18n-tasks. I've set GOOGLE_TRANSLATE_API_KEY in my .env.development file, but it looks like i18n-tasks doesn't load the Rails environment, so I get this error:

$ i18n-tasks translate-missing
i18n-tasks: Set Google API key via GOOGLE_TRANSLATE_API_KEY environment variable or translation.google_translate_api_key in config/i18n-tasks.yml. Get the key at https://code.google.com/apis/console.

It would be nice if i18n-tasks could work together with dotenv-rails to load these env vars from .env files.

Also I realize that it's very difficult to maintain an open source project, so if this is too much work or no-one else wants it, then please feel free to close it. Thanks for all your work!

@ndbroadbent Just an idea: I recently found https://direnv.net/, which is a more general solution to the same problem and should fix your problem as well.

This would be good for DeepL as well, which can't be controlled by environment variables at all.

you can do the following to pick up variables from dotenv:

bundle exec dotenv -f ".env.development" i18n-tasks translate-missing

Lines 66 to 68 in 105c0f4

	conf[:deepl_api_key] = ENV['DEEPL_AUTH_KEY'] if ENV.key?('DEEPL_AUTH_KEY')
	conf[:deepl_host] = ENV['DEEPL_HOST'] if ENV.key?('DEEPL_HOST')
	conf[:deepl_version] = ENV['DEEPL_VERSION'] if ENV.key?('DEEPL_VERSION')

@glebm ok, it's been there for years, apparently :D I think this should be mentioned in the README.md though, as it's only obvious from reading the source.
