I hate it when I make an official release of a program with an ugly snippet of code that I can't figure out how to write more cleanly, only to come up with a solution 10 minutes after pushing the release. I just make the change in the dev branch so it gets incorporated into the next version.

In my defense, the thing I was overlooking was that #Haskell's Maybe type is an instance of Foldable. It's not the kind of data type that exactly screams Foldable, is it?

Side note: I should use Hoogle's search by type signature feature more frequently. I needed a function that looked like this: Monad m => (a -> m ()) -> Maybe a -> m (), which is literally just mapM_.

So, I created a #Haskell #TUI program using brick. I wanted to have it support cursor keys, as well as vim and Emacs-style cursor movement, but for whatever reason I can't get it to register C-n and C-p keypresses. C-f and C-b worked fine though.

Anyone have any ideas as to why this might be?

data Foo = Bar { val :: Int } | Baz { val :: Int }

I'm an idiot.

I was trying to install #Haskell on a machine and thought the installer was taking a really long time. In my defense, the last line of text was:

Installation may take a while.
