I’ve long been intrigued by Haskell and recently have been reworking some existing apps in Yesod to get more hands-on experience (most notably, working on the Pi-Base). There’s a lot to like - the type system offers some pretty strong correctness guarantees, but more significantly, it makes refactoring and developing feel a whole lot less like work and a whole lot more like playing with Legos. But coming from Rails and the ridiculously helpful Ruby ecosystem, I’ve struggled to find replacements for a few of my workhorse gems.
For the home server I’ve started working on, I found myself needing to do some periodic background tasks, which probably means forking off a clock-worker. While there are lots of different ways to approach this, this is essentially a solved problem in the Rails world; you should pretty much be able to drop in any one of several gems and call it a day. I’ll admit I’m new to the Haskell ecosystem, but it doesn’t seem as cut and dried here. In fairness, this could be in part because the pieces are all already there and assembling them yourself isn’t all that bad.
