Main changes:
== texvc accepts more TeX ==
== texvc_test for mass tests ==
Tested on corpus of TeX equations downloaded and perl-extracted from PlanetMath, and it accepts 3553 of 6302.
Two things to consider about this numbers: * These "equations" were extracted by very primitive regular expression (/$([^$]+)$/), and many of them aren't really equations. * lot of those that are use features predefined in prefaces of particular articles.
It would really help if I could get real TeX sources of PlanetMath somehow. Any idea ?
== HTML rendering engine is more powerful ==
It can render fractions now, like that one:
<math>\sum^{N+M}_{k=0} k^6 + \frac{\sum_{i=1}^M i}{\prod_{j=1}^N j}</math>
What is transformed into acceptably-looking but impossible to write by hand code like that:
<table><tr align=center valign=bottom><td>N+M<td><td><table><tr align=center valign=bottom> <td>M<td></tr><tr align=center><td><font size=+2>∑</font><td>i</tr><tr align=center valign=top> <td>i=1<td></tr></table></tr><tr align=center><td><font size=+2>∑</font><td>k<sup>6</sup>+<td> <hr style="{background: black}"></tr><tr align=center valign=top><td>k=0<td><td><table> <tr align=center valign=bottom><td>N<td></tr><tr align=center><td><font size=+2>∏</font> <td>j</tr><tr align=center valign=top><td>j=1<td></tr></table></tr></table>
