I think Bozhidar's other projects[0][1][2] are more relevant as "credentials" for an Emacs mode, although probably more niche :)

[0] Projectile, a project mode https://github.com/bbatsov/projectile

[1] Cider, a clojure mode https://github.com/clojure-emacs/cider

[2] Prelude https://github.com/bbatsov/prelude

For context for those not aware, CIDER is probably the #1 Clojure repl in terms of popularity for day to day work.

Good projects. I have only used Clojure professionally for about 2 years out of the last 15 years but I lived in Cider.

When I bought my new laptop a few months ago I consciously and purposefully refused to install VSCode, just improved my Emacs setup for all writing and programming - and I have been happier for it.

I was satisfied with Tuareg + Merlin for OCaml development in Emacs, it just worked for me and didn't break when I upgraded packages, but yes, this being from bbatsov is a strong incentive to try it out. My only concern is that it uses tree-sitter, which I try to avoid because of the messiness of the JavaScript ecosystem.

I think tree-sitter's relationship with JavaScript is entirely syntactic. You don't need any JS runtime installed to write grammars, because technically tree-sitter CLI already has a JS runtime included and using that it converts your grammar first to an intermediate JSON format, then it generates parser code in C. And then this C code gets compiled into a shared library, which is what editors like Emacs use, so to use tree-sitter modules you definitely don't need a JS runtime either.

Aren't there specific IDEs for OCaml like for more mainstream languages?

Vim/Emacs/Sublime (And now things like VSC/Helix) are more than sufficient for coding without an IDE. Autocomplete scripts, the terminal, build scripts, etc work great. Now with LSP you can turn any editor into an IDE pretty trivially.

You answered it yourself. More mainstream languages have specific IDEs and OCaml is not more mainstream.

What’s the specific Rust IDE?

There is RustRover from JetBrains.

Downvote? Really? You're not allowed to ask a question any more?
