A simple Go app that will automatically archive public channels on the following criteria:

• if the channel is empty; or
• if the channel has had no activity for the last X days.

The poject uses godep to manage dependencies, so you'll need that. Once you've cloned this repo into your $GOPATH:

cd path/to/slack-archivebot
godep go build
./slack-archivebot

Heroku is the simplest option. The script can run quite happily on a free dyno using the Heroku Scheduler add-on.

Note: the above will deploy the app to your Heroku account, and add the Scheduler add-on, but won't configure it to run. To do this, go to your dashboard, find the appropriate app, open the Scheduler add-on, and add a new job that runs slack-archivebot every 10 minutes.

The following environment variables are used to configure the script:

• ARCHIVEBOT_SLACK_TOKEN: the Slack Web API key for your team.
• ARCHIVEBOT_INACTIVITY_DAYS: the number of days' inactivity after which to archive a channel (default: 30).
• ARCHIVEBOT_NOTIFY: a Slack user or channel (e.g. #general or @tblair) to notify whe 62CC n something goes wrong.

Note: you must use an API key for a regular Slack user account. You cannot use a bot user account, because bot users don't have permission to archive channels.
