I think the main win is leveraging Python’s ecosystem (especially ML/data tools) without leaving F#. Plus, cross-compiling - some teams write core domain logic once in F# and use Fable to export Python, TypeScript, etc., so external customers can consume it natively in their stack.

Surprise ! Depuis deux mois je vis dans le secret le plus absolu car j'ai été le seul YouTuber FR a être invité par Nintendo pour tester The Duskbloods en avant première, à Tokyo, dans les locaux de From Software. J'ai jamais aimé PVP et pourtant, Duskbloods c'est incroyable !

11 years ago I’ve made first commit on the project that would later be known as Ionide. A lot has changed over all those years, but one thing remains - the biggest value of the project has been meeting awesome people from F# community, many of whom I’m proud to call friends. #fsharp

Thank you for the feedback. We enabled repo-assist for Fable repository. Could you please have a look to confirm we did it right ? We decided to not run in blast mode, as it would eat a lot of tokens (cost a lost) via the Claude API. It also allows us to test how useful it is for us.

Maxime @mangelmaxime.bsky.social · 06/03/2026

It can be surprisingly good at times. But often, you need to ask him to simplify the code, make it more idiomatic at some places. Kind of like your first version of the code is never on par with your standard. Also, the more similar code you have in your code base the better.

Maxime @mangelmaxime.bsky.social · 04/03/2026

I don't know if this is because it was the first run or if this is something that will happen all the time. I also personally didn't get good result from AI in general, but another maintainer of Fable was able to create a new target quickly thanks to AI. 2/2

I will watch your Amplifying F# talk as I didn't have the time to do it just yet. One concern I have with Repo assist, is how much noise it generates. For example, on FSAC and Ionide I needed to disable notification because I received too many of them. 1/

The main difficulty for Three.js binding with Glutinum is that Glutinum only support one file at a time for now. But in theory, you can do the transformation and adapt the code where needed. You can also start porting only the API you need and not everything at once.

Something to note, is because of how Fable works you need the libraries to have been upgraded to use nullness to. This is something we are still experimenting about and we will write a blog/documentation about it later.

Maxime @mangelmaxime.bsky.social · 05/05/2025

F# nullable should works for JavaScript at least. We are looking into how to support it for TypeScript, as we originally wanted to emit native null check for TypeScript, but we will probably do it in a similar way as for JavaScript. 1/

Hello, In theory this is possible but I am not well verse into the status of the Rust target. I think it is usable but we need more users to find bugs or share their experiences. You should open a discussion on the Github repo to ask feedback from Ncave github.com/fable-compil...
