Hi, I wrote a Haskell indenter for Haskell for the Kate editor a few years ago, which – if I remember correctly – worked quite well. It's quite simple and doesn't try to bee *too* clever, but has some logic for when it should dedent. Not sure if it's helpful, but you could have a look (it's well-commented javascript):
