We're still looking for more sponsors! If you or your company can help fund this effort: Since 2017, my work on Ohm has been unpaid. Your sponsorship helps the project be sustainable, ensuring that I can maintain and improve Ohm for many years to come!.

Thanks to a generous contribution from @Shopify, we've secured enough funding to make further progress towards production-ready Ohm+WebAssembly support! Thank you Shopify for funding open source. โค๏ธ.

#503 covers the initial investigation into WebAssembly. Due to funding limitations, that work was scoped to a 6-week effort. This issue is about the next phase: productionizing the current prototyp...

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:

If you dig Ohm and are interested in WebAssembly, check out this book by @dubroy (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!.
Excited to announce the official launch of our online book, WebAssembly from the Ground Up! ๐. It's the book we wish we'd had 3 years ago. No messing with tools and frameworks. It's a hands-on guide to the core of Wasm: the instruction set and module format. Link below. ๐

Just been told that 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:

Extensible parsersโฆgreat idea! ๐.
New blog post by Hannes Mรผhleisen and Mark Raasveldt:. Runtime-Extensible SQL Parsers Using PEG. This post discusses how parsers in DBMSs could be re-designed using Parser Expression Grammars for extensibility and improved error reporting.

Still one of my favourite things built with Ohm โ. Shadama by @yoshikiohshima et al is a live programming environment for particle simulation. It compiles to GLSL shaders and runs in the browser via WebGL.

I really want this poster and am really tempted to make a version of the Ohm grammar (ohm-grammar.ohm). Hmmm and I have a long flight coming up soon ๐ค.
finally got my hands on the pascal railroad diagram poster. this is based on an original jef raskin design, as ruined by steve jobs. between this and my (repro) 1969 cobol poster, i now believe i am in possession of all extant visually appealing PL posters. is there another?

In @WasmGroundUp, we teach you how to compile a simple programming language down to WebAssembly. (using Ohm, of course). Here's a section on inline rule declarations, part of a new draft of Chapter 3, "A Calculator Language".

Another fun use case for Ohm ๐. Rail ID is a general-purpose parser for European rolling stock identification codes.

Maybe the @_ohmjs editor will be available in VSCode in the future. ๐. (still some work to get there!)

Thanks to some hard work from @andrewelgert, we now have Ohm grammars for modern versions of JavaScript (ES2015+). Give 'em a spin and let us know how they work for you! .

ICYMI, the last Ohm release came with a sweet new feature: examples embedded in comments. โ Positive examples begin with //+.โ Negative examples begin with //-.โฆand an `extractExamples` helper to easily add them to your tests.
