A bot for Slack written in Go (golang) that politely reports when a link has been used before in the channel.

• Build the code with go build

• Start the bot with ./slack-oldbot on an internet-accessible server. (Check the output of ./slack-oldbot -h for configuration options)

• Configure an Outgoing Webhook in your Slack and point it to the place where your bot is running. For example: http://example.com:8000/

• The bot will listen to incoming requests, extract urls, add them to the list, and if they've been used before, it will respond in the channel.

• Export your team's data from https://my.slack.com/services/export, and use that to seed the bot. See the -importDir and -importChan options.
• Keep your bot scoped to one channel.
