writing parseff is mega fun this is a parser for a key/value (with utf8 support)

OxCaml is the extension of the extension of a dialect of ML If we fork OxCaml to add mlx... ex of the ex of the ex of ml

a pull request out of the blue 10 minutes after I publish in ocaml discord... just feels nice

Parseff, a parser combinator library for OCaml 5

If you try opencode, it's really hard to go back to claude Even now that opus/sonnet won't work in oc. I just hope 5.4 codex and other models become better, and oc implements some of the cool features from cc

Parser combinators are great until your code becomes operator soup `>>=` `<|>` `<<=`

BREAKING (nothing is broken): I just deployed a new html_of_jsx documentation site build with mlx, yocaml (@xvw.lol) and ochre (for the syntax highlight, still wip). That's what's possible with doc-markdown and odoc 🎊

Every Haskell project is just an identity choice. Nobody cares about the code. The "written-in-haskell" IS the product. Nobody picks OCaml for a web app because they ran the benchmarks. They pick it because they want to be the type of person who writes OCaml for a web app.

I love how @bobkonf.bsky.social become the 2nd house for ocaml talks

I have a mutual who's a developer who teaches me functional programming for free and always puts a lot of effort into sharing open-source projects, talking about them but I feel a bit bad because nobody uses them. One day I went to their profile to see who they were and it showed me 'edit profile'

who said you can't have nice documentation in OCaml?

Wow Eliom + Wasm Of OCaml is released (thanks to the @ocsigen.org toolchain) ! discuss.ocaml.org/t/eliom-12-c... #OCaml #ocsigen #wasm

i didn't expect opencode would make me install nvim...

this is what claude code was doing before your silly prompt

people, I found the absolute best name I could possibly imagine for a reason/ocaml project... a syntax highlighter called ochre

Time to go for a run

such a great feeling when you find all your stack used in the wild

TUIs are hot

poc: vibecoding from the slopes

me (to my friends who don't understand ai): you should always validate gipiti's answers, security matters alot, blabla also me: don't even read the output by whisperflow, --dangerously-skip-permissions, no plan mode, accept any code change without reading, not even a in git, auto deploy to prod

zo.computer is the real openclaw + Mac Mini I just installed pi, so I have an orchestrator for 5 instances that I can access anytime and ask them shit like schedule a barber, but also, clone repos, push PRs and deploy to fly.io feeling the agi rn

Finally I had time to finish!!! react rules of hooks for reason-react components - feature complete - deployed in our monorepo - linting the effects, the memos, the everything github.com/ml-in-barce...

I just implemented context support for React Server Components in server-reason-react. unlike React.js where createContext/useContext are client-only, our OCaml implementation supports context in server components, including across Suspense boundaries.

pov: I just opened my first non-trivial PR into ocaml/ocaml

1M context window changes the game again, I spend 2 weeks "cleaning" up rules, moving some into skills, some into hooks... and that's kind of useless now? I'm not super sure, been using it for 4 hours, but the model doesn't get dumb anymore I need to test the limits, to know more

Native support for mlx in the ocaml-lap-server (syntax highlight, and all LSP features from ocaml in mlx)

Adobe buys semrush (our biggest competitor)

This is pretty sick React.cache was a missing piece for RSC to work well™ github.com/ml-in-barce...

Modular explicits are coming to OCaml 5.5 🎊🫰🥳🎉🎂 github.com/ocaml/ocaml...

At this point, Github should implement the same UX as cursor to annotate files. The attention to details is so well done with the @ menu to annotate files/past chats/folders... that's the only reason why I'm still using Cursor over claude code

I finally released v1.0.0 of a ppx that enforces the rules of hooks for reason-react - exhaustive deps in useEffect/useMemo/useCallback - order of hooks (hooks at the toplevel/not conditionally) github.com/ml-in-barce...

retweet so my gf picks it up and chooses wisely

I really want to have my monitor floating in an arm like this one, but... is there any that isn't ugly as shit? Looking for one that can hide cables, doesn't look so industrial, and is visually more linear. Does it exist? x.com/indoorheart...

Maybe a hot topic, but Gitter was everything we ever needed No Slack, nor Discord, nor discuss, nor Zulip... and def not MS Teams

I have a lot of thoughts about oxcaml (complexity, compatibility, blabla) but for me, oxcaml is the future of low-level

Yes, LLMs make you more productive when you know exactly what has to be done

The time has arrived, styled-ppx won't support ReScript v11/v12 going forward Incompatible ppxlib, massive maintenance work and uncertainty about the future of ppx are enough reasons to pull the trigger Melange and native OCaml remain fully supported 😭😭😭

if anyone else here is like me and wants a Discord alternative that has an entirely different set of values *and* is pretty close to feature parity: I've been working on fluxer.app (@fluxer.app) 👀 fully open-source, self-hostable, but I really need some more funding and support to keep going!

Amazing way to promote and prove yourself to be honest

pov: first time installing base, yay

I built my own JavaScript runtime in OCaml I wanted to see how far OCaml could go against Bun and Node, and also also OCaml vs zig vs c++ in similar APIs. So I built `sirocco`. Uses JavaScriptCore (same engine as Bun and Safari). Event loop with libuv and it's written in OxCaml.

2025 was a pretty good year for me. The goal here is to share more of my work, trying to build a group of people interested in react/ocaml/webdev (but software in general), helping each other and being obsessed with learning Happy new year, lovely people

without cheating, what would return? jq -n '1 + 42' # 43 jq -n '[1] + [42]' # [1, 42] jq -n '{a:1} + {b:42}' # {a:1, b:42} jq -n '{a:1} + {a:42}' # ???

getting ghosted after this cold email 😭

deployed big update to rsc-playground.pages.dev lots of bugfixes and a few new examples. this basically works now! i'll open source a bit later

yes, but of course, every time I choose ocaml, it is a completely rational and unbiased decision

React’s JSX shouldn't be a one-to-one transformation. The react compiler should do many JSX optimizations (similar to millionjs or html_of_ppx)

Made og images from my blog to be screenshots of the blog itself (and a little footer!) Nice improvement, isn't it? Now I need to stop writing 400 words at the start and place a cute image

Doing some static analysis in the preprocessor is the perfect use-case for a ppx, and a much better solution than a library. - another win for ppxes - another win for mlx bsky.app/profile/dav...
