I've copied the example available in the readme file and it doesn't work and I can't figure out why. I'm getting the following error:

Which version of the library you're trying to use?

Right. So the example in current master is for the latest version, 1.1.0 (also works with 1.0.0). Stackage apparently included the fresh readme because forma-1.1.0 is in nightly snapshots. You can go to Hackage though and look at the older version of readme there:

https://hackage.haskell.org/package/forma-0.2.0
