Continuations for Web Development

One of the distinguishing features of Racket’s built-in web-server is that it supports the use of continuations in a web context. This is a feature I’ve only ever seen in Smalltalk’s Seaside before, though Racket’s version is more powerful.

Announcing forms

Today marks the first public release of forms, a Racket library for web form validation. Racket’s formlets module from the standard library already does something similar, but, unfortunately, it lacks any facilities for easily showing validation errors to end users which is a big part of what I want from this kind of library. Another nice thing about this new library is it’ll be able to validate things other than forms – like JSON – soon!

Advent of Racket 2018

I decided to do this year’s Advent of Code in Racket and stream the whole thing. We’ll see how far I make it (getting up this early is rough!), but so far I finished day one. The code is here and the playlist for the recordings is here.

If you want to get notified as soon as I jump on to start streaming, you can follow me on Twitch.

I’ve been playing around with Racket every chance I got since early September of this year. This post is going to serve as a sort of experience report of my foray into Racket so far.
