Hey #fsharp what are your thoughts on github.com/fsprojects/f... ?

@dsyme.bsky.social a bit unrelated but I poked you on F# slack in case you missed it.

F# folk, with @nojaf.com we've added support for generating llms.txt to the fsdocs tool that's widely used by the F# community.

We'll release it soon but if you have a chance to take it for a spin before please do.

Dear #fsharp, we're asking again about a possible Fantomas default change: github.com/fsprojects/f...

With 500+ downloads a day and only ~130 votes, we simply don’t have enough data yet. Absolute numbers matter before making such a decision.

Real talk: without a challenger like @bun.sh this would never have happened.

In the next version of our vscode plugin 🚀:

Hi #fsharp we *might* consider changing a default in Fantomas: github.com/fsprojects/f...

I Built an MCP for My ReScript Project and My LLM Went Super Saiyan YouTube video by nojaf

Been building a @rescript-lang.org MCP server lately, letting an LLM truly see a codebase.
If you haven’t met ReScript before, this one’s still worth watching . It has a clear case of how localized MCP servers can lift developer tooling.

Had a lot of fun with this!

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.

In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

Never use your default branch to send PRs in GitHub!
Maintainers can't push to that branch, even though if you enabled "Maintainers are allowed to edit this pull request."

The editor tooling in #ReScript has immense potential. I'm very happy to be among the core contributors and learn from the best!

Working on preserving JSX in #ReScript output at the @rescript-lang.org retreat!

Upcoming ReScript (@rescript-lang.org) v12 move platform binaries into optional dependencies (e.g. rescript/linux-x64)

To shrink the download & install size significantly!

Download & Install size change:
- Before: 67 MB | 197 MB
- After: 15 MB | 48 MB (on a Linux x64 machine)
