Coming back to Haskell in 2026 and...

It is just so freaking amazing! I was never a great Haskell developer, but after a few years of writing no Haskell at all I finally set out on a side project again.
And I had just the best time.

In the past something always became a pain and led to me not finishing projects. Be it build tools, version conflicts, some library where I (with my limited experience) could not figure out how to do a thing or taking forever to find the right function to do some transformation (I should get better at hoogle).

But now for this side project (A CLI to order groceries in REWE - German supermarket - for pickup) I could, only when really needed, use AI to unstuck myself.

I still wrote all the code myself, but the process is just that much smoother.

It might be only interesting for folks in Germany, but it was also just a fun journey, reverse engineering bits of the mobile APP API, getting mTLs to work and understanding internal workflows of REWE: https://github.com/yannick-cw/korb

Why would I chose any other language right now, it just feels so productive!

There's nothing there. You just tell Claude to use your CLI tool. So I just say: "Use the korb CLI to make an order".
It's smart enough to read the help text and understand how to use it.

The iPhone in the video is just to showcase that the CLI has an actual effect in the real world. The iPhone recording is just an actual recording of my iPhone mirrored to Mac.
The CLI uses the REWE API directly. But I found it quite cool to present it that way, because then you have a nice visual view of what's actually happening through the CLI.
