Chamber

Chamber is a tool that translates Slack messages using The Microsoft Translator API. Currently, Chamber supports translating from English to Japanese and from Japanese to English. The name of Chamber is taken from the character by the Japanese animation 翠星のガルガンティア (Gargantia on the Verdurous Planet).

Requirements

• Configure Slack

  • Create an outgoing web hook by selecting "Outgoing WebHooks" from the "Add New Integrations" option on the Slack Integrations page.
    • Set on the "Channel".
    • Not set on "Trigger Word(s)", it's important.
    • Set a server url (like "https://chamber.example.com") on the "URL(s)". If you have a valid certification for SSL, you should use it. But self signed certification does not work.
  • Create an incoming web hook by selecting "Incoming WebHooks" from the "Add New Integrations" option on the Slack Integrations page.
    • Set on the "Channel".
      • It is recommened that you set the channel that is the same as "Outgoing Webhooks", because this tool seems true to bot.
    • After creating the web hook, you can confirm the token of the integration.

• Configure a Windows Azure Marketplace account

  • If you don't have it, you can create the account in https://datamarket.azure.com/ .
  • Create an application with Microsoft Translate API.
    • After creating the application, you can confirm the client secret of the application.

Translate

If you don't understand the latest message in Slack, let's ask Chamber!

English -> Japanese

Bob> A rolling stone gathers no moss.
r9> @chamber: 彼は何と言っている？
chamber> 「転がる石は苔むさない。」と言っている。

Japanese -> English

r9> 終わりよければすべてよし。
Bob> @chamber: Translate
chamber> "All's well that ends well."
