Course using F#: Write your own tiny programming system(s)

1. coollang-2020-fs

   1 5 38 9.2 F#

   Compiler of a small Scala subset

   

   Looks interesting.

   Once I saw it's a Czech university course using F#, I knew Tomáš Petříček would be the lecturer :)

   A couple years back, I wrote a compiler of tiny-ish scala subset in F# (the code is imperative, though)[1]

3. teaching

   2 1 102 6.9 F#

   :mortar_board: Materials for my lectures including programming langauge design, software engineering and human-computer interaction.

   

   There seems to be a lot of confusion for this, unfortunately.

   Some more information can be found at https://github.com/tpetricek/Teaching (specifically, https://github.com/tpetricek/Teaching/tree/master/2023/tiny-...). The course is currently ongoing. The videos and PDFs seem to be down, but I wouldn't be surprised if that's just because of hacker news overloading things.

   Seems neat, from the slides and demos.

4. Avalonia.FuncUI

   3 30 1,031 6.6 F#

   Develop cross-plattform GUI Applications using F# and Avalonia!

   

5. Elm

   I started down this path sometime last year with Crafting Interpreters and I’ve gotten obsessed with this entire world since. I wrote a little language [0] using Python Lex Yacc a couple of months ago at work because I wanted an awk-like way to quickly make graphs/charts from the CLI. Then I wrote a parser-as-a-type in TypeScript [1] for the same grammar.

   My plan was to take a look at OCaml for future tinkerings with parsers, but man, F# is already looking very familiar between TypeScript and Lex/Yacc-like things.

   Thanks for this post, I think I might have a new favorite language in the oven!

7. Fabulous.Avalonia

   6 3 144 9.0 F#

   Declarative UIs for Avalonia with F# and MVU, using Fabulous

   

   Also take a look at Fabulous[1]. The code with it looks nicer than Avalonia.FuncUI.
