BraidMail

A Braid Chat bot that lets you manage your email from Braid.

Development

Create config file config/dev.exs and fill in the appropriate information. See config/test.exs for a reference of the config info that should be set. See below under "Integrations Setup" how to get the various API tokens.

Run mix deps.get to fetch all dependencies.

Run mix ecto.create and mix ecto.migrate to set up the database.

Deployment

Create config/prod.exs and populate it with the appropriate information. See config/test.exs for a reference of the config info that should be set.

You'll probably also want to put config :mnesia, :dir, 'data/mnesia' in prod.exs.

To create the release artifact, run

$ MIX_ENV=prod mix release --env=prod

Then find the created tarball under _build/prod/rel/braidmail/releases/, upload it to your server, and extract it. You'll also want to create a directory for the Mnesia database (e.g. mkdir -p data/mnesia). The bot can then be started as a daemon with bin/braidmail start or bin/braidmail foreground to run in the foreground (e.g. with Supervisor). To point the database to the correct host, you'll need to set an environment variable: MNESIA_HOST=braidmail@127.0.0.1. This only seems necessary when starting the server, but not when running the migrations.

Connect to the running process with bin/braidmail remote_console.

Integrations Setup

Braid Config

Add the bot to your braid group.

The message webhook URL should be https://<bot address>/braid/message

Leave "Enable All Public Messages" unchecked and don't set the "group event webhook URL".

Put the "Bot ID" in the config under the key :braid_id and the "Bot Token" under the key :braid_token.

Gmail API Keys

Go to the developer console and create a new OAuth-flow app. Put the "client id" value in the config under the key :gmail_id and the "client secret" under the key :gmail_secret.

The "Authorized redirect URIs" should include whatever address the bot is accessible at, with the path "/gmail/oauth2".

Put the URI you set as the authorized redirect URI in the config as :gmail_redirect_uri.

You also need to enable the gmail API for the project, which you should be able to do from the developer console by going to dashboard, then clicking "Enable API", then selecting Gmail.

Installation

If available in Hex, the package can be installed by adding braidmail to your list of dependencies in mix.exs:

def deps do
  [{:braidmail, "~> 0.1.0"}]
end
