What does HackerNews think of fsharp?

The F# compiler, F# core library, F# language service, and F# tooling integration for Visual Studio

Language: F#

#20 in Compiler
#8 in .NET
#5 in JavaScript
Can't speak to the others, but I'm pretty sure the F# team just doubled or tripled in size (it's still small though). Also the GitHub repo is very active: https://github.com/dotnet/fsharp .
> the Microsoft .net core compiler is FOSS

Oh, I didn't know that.

Very cool.

Can I apt-get the toolchain?

[EDIT]: and for those interested, here's the github repo:

https://github.com/dotnet/fsharp/

You can simply contribute to https://github.com/dotnet/fsharp/, the maintainers are very friendly to new contributors in my experience (though the codebase is old and often quite hard to understand).
Yeah, that's a rather large type definition We used to have some issues in the compiler in processing records that are 250 or more labels large, and can process ones with 1000 labels or more. But it's still a pain point, especially if it's generated, since those can get large pretty easily.

The issue you're describing sounds more like a compiler/core tooling issue than a Rider issue though. Would you mind filing an issue here? https://github.com/dotnet/fsharp

We collaborate with the Rider folks quite a lot and so they'll see this if it is indeed a Rider issue.

This is not about being open-source, but about being popular.

OCaml is a fine language, but it's not a wildly popular one. Should the authors have started with, say, Python or JS, they won't have the problem with support from third parties. Please note how their choice was between open-source Rust and proprietary (CORRECTION: also open-source already) F#, both descendants of the ML family.

When you pick a language and start to feel you're overgrowing its ecosystem, you either migrate off of it (as in the post), or start developing it to help it move in the direction you want. In the case of OCaml, Jane Street and Facebook chose the latter route.

UPDATE: Thanks for reminding that F# has been open-sourced: https://github.com/dotnet/fsharp/

I don't believe F# has been abandoned. It's actively being maintained.
