I develop a tool that needs to process text as a mathematic statement and computes result. In the text users can use predefined functions.I use JEP for process this text, but I want to use a better tool.Do you have any suggestion?
I'm not sure about the specific needs of your application, but you might want to consider using EL.(The same expression language used in JSF)There is an excellent open-source implementation of the expression language available called JUEL.Link: http://juel.sourceforge.net/I've used it and I was happy with it.(Actually my other teammates are more eligible to comment on this now)
Have you ever tried antlr ????????????????
If your Application is on the WEB, I used JMath to handle text to math formula, it's nice and fast.
