For anyone interested in the slides & videos, those are now accessible again! Sorry for the technical issues (it was not the HN effect, but a migration to a new disk...).
For anyone not familiar with the fsharp community, tpetricek has made fantastic contributions. Not a week goes by I don’t Google something and end up at a stackoverflow answer or fssnip entry he wrote.
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 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!
You should be able to use Avalonia UI[1] as an alternative GUI layer on Windows, Linux, macOS, iOS and Android.
There is a beautiful functional MVU wrapper around it called Avalonia.FuncUI[2] with Avalonia.FuncUI.Elmish[3] which is an implementation of Elmish[4] (based of the Elm language[4]) for F#.
WinForms is a Win32 wrapper so unless you're running Mono which I don't think has been targeted by F# in ages I don't think that's going to work, unless you plan to run a very old F# version.
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]
