    I wrote a parser combinator library for TypeScript that I have been having a lot of fun with [1]. It has limitations, I wouldn't use it to write a full language programming language like Gleam, but for "language-ish projects", parser combinators can be lovely to use. I used it to build a typed version of Mustache [2].

    > Rather, I’m after a particular kind of software hygge: Loads instantly, doesn’t crash, and fits nicely in the hand.

    The author is talking about the language, but this is what parser combinators feel like to me, and could be another option. Tarsec is probably the most fun side project I have built in a while.

    I have a short and a long intro, both illustrated: https://github.com/egonSchiele/tarsec/blob/main/tutorials/5-... and https://github.com/egonSchiele/tarsec/blob/main/tutorials/th...

    It also has a neat debug mode, and a way to benchmark performance. I've loved using it, hopefully someone reading will use it too! Use this as a chance to learn something cool (parser combinators)!
