I just poked about a bit on the ActiveMath site. I could not get into the CVS, btw. It does not allow "anonymous" and "guest" wants a password. Very interesting stuff.
Fixed, fixed... I find it partially a shame that maven 1.0 was released without even support for such overrides...
Just to explain this bit, JomeConsole is, mostly, a wrapping:
- of Jome
(http://www.activemath.org/projects/Jome/ actually a
finished project of ESSI/INRIA Nice)
providing the linear-parser to OpenMath (string)
- and a little evaluator using jdom and walking the jdom tree (of OpenMath elements) to evaluate the function
Jome is LGPL with main purpose to provide a "formula editor" for OpenMath. It's quite old, relying on an even older library of INRIA. Among the errors, I think, Jome is using as core model a linear-syntax model (which makes, e.g. a "+" a first class citizen).
Jome owners might, I believe, consider a donation at Apache... but it's main purpose is user-interface!
JomeConsole (including the evaluator) is MPL, could be donated with pleasure but is really small!
I have a couple of questions for you. First, would you be willing to contribute / relicense, whatever, the expression parser that you mentioned in your mail to commons-math? I could not find the relevant ActiveMath code in the downloads that I grabbed so I don't know exactly what we are talking about here. Could you tell me where the relevant classes are (and if you would be willing to contribute them to [math])? If so, we can talk about it on the list. Actually best to respond to this question on the list.
We had been exchanging with Mark a few months ago about where to find a package for formulae and there was nothing finished. One of the trends was Math-Beans, I think there's a little part in the source-tree currently.
I remember, at the time, already being annoyed by the dichotomy between complete generality (e.g. that matrices could be able to have entries in any ring) and... feasability. Currently, I think, what's in there considers more or less real numbers only, maybe complex numbers, but no fancy ring like Z_p or a ring of polynomials.
Mark was clearly stating that there's an amount of packages around that do formulae... (I remember now of Dautelle's JADE, http://www.dautelle.com/jade/) and that it was better to expect a donation from somewhere else...
Now this somewhere else hasn't come yet... maybe we should hunt and link around before ?
