By fix this do yo mean fix texvc or fix correct the wikicode?
To fix the wikicode: Ensure all decorations \dot, \vec, \tilde, \hat, etc, and
font chagnes (\mathcal ) place curly braces {} around their arguments.
Depending on the circumstances this is not strictly speaking always required,
but it will always fix any problems.
Examples
Bad LaTeX: Fixed:
\tilde\mathcal f \tilde{\mathcal{f}}
\dot \vec B \dot{\vec{B}}
But when upgrading this could potentially break a lot of formulas. But I defer
to your judgment about what is or is not a blocker.

--- Comment #14 from Nicholas Longo 2011-10-13 16:39:34
UTC ---
Explanation of Parser behavior.
The parser previously added many braces (aka { } ) around expressions
generously. This was causing issues with commands that produced space and was
breaking some commands. For example It would translate
\operatername{sen} x to $${\operatorname {sen}}x$$ does not
produce the correct result.
As a result the extra braces were removed. This causes strange behavior
relating to math accents in the following ways:
1. Code that would used to compile under LaTeX is no longer sanitized to work
under texvc. Examples include 1 from comment #10.
2. The amsmath package changes the way accents are handled (as discussed in
their user documentation). Texvc only loads amsmath as needed. Which means if
a command such as \text appears then the behavior suddenly seems to change.
This is why Which is why \dot\vec B will not render but
\text{rot}\dot\vec B will render, but incorrectly.
Technically speaking amsmath insists all math accents use braces on all math
accents. Thus despite the example the example of
\text{rot}\dot{\vec{B}} actually compiling other examples do not
compile exactly because of amsmath such as \tilde \mathcal{M}
which is what was happening at the Mellin Transform page. This code $$\tilde
\mathcal{M}$$ is fine as vanilla LaTeX but not accepted by amsmath.
I am testing a patch now which does the following:
1. Restores the original placement of braces of braces.
2. Introduces a new function specifically to handle commands which are brace
sensitive such as \operatorname.
3. Removes some unneeded white space for the sanitized LaTeX.
I could use the following information/examples if anyone comes across them:
Potentially many other examples of incorrect LaTeX were sanitized into working
by way of adding braces. Do we know of any examples of things that broke that
do not involve a math accent such as \dot, \vec, \tilde, \hat, etc.?
I am interested because I think it would be wise to document the ways in which
in which texvc extends/differs from LaTeX. There is, and has been for a long
time interest in moving away from texvc to blahtex, mathjax, etc. And if we
cannot give guidelines as to the non-standard LaTeX occuring within the
wikimedia sites, it could be a rough transition.

I've tested Mediawiki 1.18 with preview, saved article, with login and without on FireFox 7, Opera 11.50 and Chrome 14. Tested sites include now Commons, MediaWiki.org and Incubator with preview. Don't know if texvc reacts on browser?

I've found some circumstances under which improper (misplaced) rendering
happens.
Code is tested on de.wikipedia.org and en.wikipedia.org
# \dot \vec B not rendering
# \dot {\vec B} proper rendering
# \dot \vec B = X not rendering
# \dot \vec B = \text{X} improper rendering
# \dot \vec B = \mathrm X improper rendering

Dozens (hundreds?) of pages have already been updated using the work arounds. For examples of math code that used to work and now fails, look at old versions of pages like: https://en.wikipedia.org/w/index.php?title=Orientation_(computer_vision)&oldid=430039796 http://en.wikipedia.org/w/index.php?title=Mellin_transform&oldid=428975706 Also, the example given by Biezl in Comment 1 is a special case. It doesn't generate an error. Instead in renders a qualitatively different result than prior to the update. In that example, the vector arrow now appears to the upper left of the B rather than on top of it as it did prior to the update. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.
