looking for simple exp parser

Hey folks,
Ive seen a simple expression parser before some time and was not able to find it again
So if anyone knows a parser for simple math expressions (at least +-*/) with the possibility to add own functions (like mySin() ) on the fly, I would be glad if you could tell me!

I think you mean iostream's parser. It's in the
german forum.
It is GPL if i remember correctly, don't know if that is useful for you.
My own expression parser does not support own functions, but maybe you want to add it yourself.
It is also in
german forum or direct d/l @
EvaluateExpression.zip.
No license restrictions, do what you want with it.

thanks a lot, the one written by iostream is what I was looking for. As long as Im in the developing stage, the license thing is okay. In the worst case I would write one by my own, but thats waste of time if there are already good ones developed.
Your parser was btw the first one I tried out today and it looks really great. Custom function callbacks would be a nice enhancement
