The next step will be to extend the grammar with the feature of transforming such expression "1+2+var_+3=4" into this "var_=4-1-2-3".
I think the attached program solves that problem.
The problem I've been working on is to use the distributive law to simplify expressions at compile time. For example, I'd like to transform "var_ * 2 + var_ * 3 = 4" to "var_ * (2 + 3) = 4". Then, you could transform it to "var_ = 4 / (2 + 3)", all at compile time. Wouldn't that be cool?
Yes!
I think it's possible using Proto, but I haven't worked out the details yet. Any suggestions are welcome.
<snip> Pretty cool, Dave. I wish I had more time to lend a hand, but you and Kim seem to be doing just fine on your own. It makes me really happy to see folks finding interesting uses for Proto transforms. -- Eric Niebler BoostPro Computing http://www.boostpro.com
