It's a bot for Slack that generates memes! But don't take my word for it. Let me show you.
/meme success-kid wrote a meme generator; in haskell
It works because of tightrope, a magical library that makes it easy to write slack bots. And also because of Cairo (a rendering library) and Pango (a text layout library).
The following build instructions are for Mac users. It's a lot more straightforward on Linux.
This project relies on cairo and pango. If you don't have them already, you can install them with Homebrew like this:
$ brew install cairo --without-x11
$ brew install pango --without-x11
Afterwards, I'm pretty sure you need gtk2hs-buildtools for something.
$ cabal install gtk2hs-buildtools
Make sure you don't install that into a sandbox! It adds some binaries that you need. So make sure ~/.cabal/bin is on your PATH.
Afterwards, we do haskell things:
$ cabal sandbox init
We have to install the Haskell pango bindings separately because clang can't build it. Look, don't ask me.
$ cabal install pango -j --with-gcc=gcc-4.8
Then we install the rest:
$ cabal install -j --only-dependencies
Okay! Now we can use it. But first we need to edit the conf file and fill in useful values -- like a token so it can post memes back to Slack, and the domain of the slack account you want to run it on.
$ vim conf
And that's it!
$ cabal run
