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

How does it work

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).

I wanna run it myself

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
