Hey. I am Lukasz Stafiniak.

This was written looong ago and then my life took a different turn. But the ideas seem worthy enough not to delete them.

Under the licentia poetica:

Calc is just Calc. You use Calc for math. You need two things for doing Math - the brain, and the Calc. Math was discovered only after discovering writing. You can do Math just with your mind (that’s a good exercise), but you need books to learn from, and you need to write down your ideas to make place for new ones. Then you can go back and forth, with no worry of forgetting, you try different manipulations and watch how they help your understanding. In the old brave times mathematicians and physicists used pen to do that. Would you imagine? Nowadays, we, common people, can do math with Calc.

The idea is to make Calc the math buffer of Emacs. It would be a formula editor and manipulator, controlling the power of the many mathematics systems, interacting with your source code, in any language. With such a math-board, different systems could be bridged to work together, for the best cross-use of their features and libraries. And, first of all, it should be a convenient editing tool, in the broad sense.

The idea of drag & drop comes from proof assistants, I think. (For example, Coq’s interface, PCoq, and Proof General, Emacs’ generic interface for proof assistants.) Some ideas are described in the paper “Proof by Pointing” by Yves Bertot, Gilles Kahn and Laurent Thery (the paper can be found at INRIA webpages http://www-sop.inria.fr/croap/ctcoq/help/pbp.html ).

I hope to write a package independent of Calc (but it’s all yours, Calc) for Lexing-Parsing-Pretty Printing, e. g. lp^3 (or Languages Per Free) so that it can be used for other purposes than Calc as well.

I’ve started the work on lp3. Done: the overall structure for stand-alone lp3. In future I plan to make it a Semantic satellite and perhaps implement 2D general parsing. (sorry for delays)
