Hey everyone, just FYI: After investigating, we do *not* believe that ohm-js, or any other package under the @ ohmjs namespace, is affected by the Shai-Hulud worm or any of the recent npm supply chain attacks.

Any Ohm fans who want to get a taste of low-level programming? Get 25% off the only book in the world* that will teach you WebAssembly with Ohm! (*So far.)

First new release of Ohm in…eh *pulls at shirt collar* quite a while. v17.2.1 is here…one small l'il feature and a teeny weeny fix: github.com/ohmjs/ohm/re... Also pushed v2.0.1 of @ohm-js/cli.

For more info, see: www.inkandswitch.com/ambsheets/no...

Pretty pleased with the ergonomics of the Wasm (macro-)assembler in @ohmjs.org. It's built on the low-level assembler lib we created for @wasmgroundup.com, but has some nice higher-level features, including labeled breaks. I'm particularly proud of the idea to put the block label at the end. 😊

You know about the Ohm Discord, right? Great place to ask questions, get feedback on your grammars, and hang out with the some of the friendliest folks out there. discord.gg/KwxY5gegRQ

Thanks to a generous contribution from Shopify, we've secured enough funding to make further progress towards production-ready Ohm+WebAssembly support! github.com/ohmjs/ohm/i... Thank you Shopify for funding open source. ❤️

A few different Ink & Switch projects have used Ohm…here's the latest one. From @alexwarth.bsky.social (co-creator of Ohm) and @geoffreylitt.com (who made Wildcard, one of our all-time favourite Ohm-powered projects)

Ever wanted to use Ohm from another language? Go, Python, Rust? See the brand new, experimental support for compiling Ohm grammars to Wasm: github.com/ohmjs/ohm/d... It wasn't the main goal, but it also appears to be a perf win — parsing is about 10x faster on real-world grammars (e.g. ES5).

One of the biggest production users of Ohm that we know of is Shopify. They used Ohm in the Liquid HTML parser that powers their prettier plugin & VS Code language server — as well as the Shopify Admin's CodeMirror-based editor. www.npmjs.com/package/@sh...

Working on a cheat sheet for @ohmjs.org grammars. wdyt?

Making progress on the Wasm implementation — and encountering some interesting challenges!

Made some good progress on this! Follow along on the issue if you're interested: github.com/ohmjs/ohm/is...

Hey folks, we had another Cloudflare ⇆ GitHub SSL issue which meant the web site was down for about an hour. Thanks for @onlineornot.com we found out pretty quickly, and it should be fixed now! And we'll be getting rid of Cloudflare so hopefully we'll be rid of this problem for good 🤞

Wondering if the book is *practical*? I'm currently using the helper library extracted from the book for a new @ohmjs.org feature which will allow you to compile Ohm grammars to Wasm. This will make it possible to use Ohm grammars from Go, Python, etc. Details here 👉 github.com/ohmjs/ohm/is...

Excited to kick off some new Ohm work next week — adding the ability to compile an Ohm grammar to WebAssembly. See github.com/ohmjs/ohm/i... if you're interested, and feel free to comment if you have opinions!

Very cool to learn that Ohm was used to create Gambu-Script, which is used to teach programming to over 90k students in Austria! It's part of SchuBu, a free-to-use digital schoolbook: www.schubu.org/p768/progra...

If you dig Ohm and are interested in WebAssembly, check out this book by @dubroy.com (co-creator of Ohm). You'll learn Wasm (the instruction set and module format) by building a compiler for a small programming language. It's also a great way to learn Ohm!

Anyone catch Ohm in the current edition of JavaScript Weekly? javascriptweekly.com/issues/723

Just been told that ohmjs.org is currently down. Sorry about the disruption! We're working on a fix, but in the meantime, if you need to access the docs you can find them here: github.com/ohmjs/ohm/t...

Constraint-Based Spreadsheet, 2014. An attempt to make spreadsheets more powerful and user-friendly by replacing one-way formulas with multi-way constraints. Check out the source code (@ohmjs.org inside!) and play with the live demo at github.com/harc/constra...
