For centuries, people have wondered: "What's the fastest way to get a JPEG into a Slack channel?" Scientists now believe that jpgtobot is the answer. To verify these findings, please

• Install Haskell (Windows, Mac, and Linux);
• Install Stack;
• git clone https://github.com/hlian/jpegbot/ && cd jpegbot && stack build;
• Create a Slack incoming token and save it to a file named hook;
• Create a Google Custom Search API key and save it to a file named google-server-key (see this);
• Create a Google Search Engine and save the ID to a file named google-search-engine-id (see this again);
• stack exec jpgtobot.

• Use ngrok to open a tunnel to port 3000 (ngrok 3000);
• Copy down the ngrok URL;
• Create a Slack custom command /jpeg POSTing to that URL;
• In Slack, type /jpeg corgi.

If all goes well, you'll see something like this:

A demo app for Network.Linklater, a library I wrote! It lets you write Slack bots very easily. Please check it out, whenever you have free time.
