xcalc is useless. I was thinking of building a terminal based calculator for dsl that would process C style equations on a line by line basis and have support for user variables. Does something like this already exist?

not sure whether to do it in C (fun) or C++ (easy).

_pathos, I'd like to see what you come up with.

I found a mind reader...

I'll build a front end and add binary/octal support. Maybe even arbitary length numbers with GMP Bignum.

I had been hoping to use a hack I had worked out using a separater operator stack for precedence...it would work but the code would have been just too cryptic and wouldn't handle syntax errors well. meh

DSCalc is progressing well. I've spent a while adding better error information.

seems to be fully functional, I have no doubt there will be a bug or two because I've found some in the existing code and I don't think its been tested very well. oh well.

Source should be available soon, just adding in program documentation.
