Re: [ANN] libmc

[Leaf Storm <leafstormrush@...>]

Now that I've really stepped back and analyzed why I'm doing this, I'm
realizing how ridiculous my wishlist really is. :-) Pretty much the
only thing I really think has a chance of getting in (besides the
"Really useful generic stuff" section) if I want to keep libmc light
and simple is the option parser. The algebraic/geometric stuff you are
right about - it's not something most people need, and would be better
in a separate library. And as for unit conversions, it wouldn't be
that it's so hard to implement, but the conversion factors would be
just really bulky.

The XML generation involves something along the lines of xml.p {class
= 'greeting', "Hello, world!"} - really, just a quick & dirty way of
generating XML. Though I used Genshi as an example, a better idea of
what I was thinking is at
http://dev.pocoo.org/projects/werkzeug/browser/werkzeug/utils.py, in
the HTMLBuilder class. It implements that in just a couple of KB,
whereas Genshi is a big library that manipulates the DOM and stuff.

Anyway, remember - it *is* a wishlist. :-)
