Hey all! I've been working on this on-and-off for a few months, but it is sort of in a broken state right now on GitHub. I'm playing with some modifications to the charts and dependency graph, and the localStorage autosave/load is a bit glitchy.

Just saw Dan posted it now, and figured I should chime in (and push my last few commits).

The version here works the OK-est, but it still needs work: http://www.omarrizwan.com/cruncher/

Hoping to get back to it sometime within the next few weeks.



Thx for the link to the better demo.

I like all the graphical add-ons like the data flow graph: you have an expression graph so why not show it to the user...

This file is very interesting: https://github.com/osnr/cruncher/blob/master/src/jison/parse... How would one have to change the grammar to allow for things like sin(30°) in the equations?


Very interesting! Could be a useful tool to teach algebra. I've posted some bug reports on github. Please keep up the good work!


Even the demo doesn't work for me in Chrome dev.


I'd love it if you could post some demo's!
