I read a slide on OMeta. http://tinlizzie.org/ometa/dls07-slides.pdf Its pattern matching is specialized in expressing pattern matching against lists and trees. Egison aims intuitive expression for a wider range of data types and provide non-linear pattern matching with multiple results on a functional language. Please check a cheat sheet and demo pages on our website. We can get its concepts easily from them. http://www.egison.org/cheatsheet.html http://www.egison.org/demonstrations/poker-hands.html

Thanks. It looks to me like Egison is focused on pattern matching of data. While OMeta is focused on pattern matching of syntax (so is used to create and extend new languages/DSLs). Is that a fair comparison?

How does the Egison online evaluator work? Server-side haskell or the ruby extension?

Any plans for a javascript extension?

What you wrote is what I wanted to write. We call the Egison command on the server limiting code with side-effects via an API server implemeted in Ruby. All source code on Egison including its website is on GitHub. Please check them, too. https://github.com/egison I’m not planning a javascript extension for now, though I’d like it.
