Discussion

On MoinMoin 1.8.3 and using firefox 3, having the format line "#format inline_latex" defined in a document crashes the GUI Editor. (When saving some modifications or after clicking the Preview button, an exception PluginMissingError while searching for a valid converter module). The exception will happen after saving or previewing some text or tables pasted from MS Word to the GUI editor.

Problem with the \over binary operator: MoinMoin 1.8.3 - both lines display correctly in mathtran but not Latex. I will block quote both lines here to avoid braces problems, and only show the first line in the example.

$ y^2 \over 2 $
$ {{y^{2} } } \over 2 $

$ y^2 \over 2 $

$ y^2 \over 2 $

A problem

I have encountered a problem/difficulty with inline_latex. My code is:

#format inline_latex scale_factor=3, mathtran_server=http://www.mathtran.org/cgi-bin/toy/
The solution(s) to

$ Ax^2+Bx+C=0; $

can be expressed:

$ x =\frac {-B \pm \sqrt { B^2- 4 A C}}{2 A} $

which goes wrong as seen at [http://hpmail.dk/wiki/moin.cgi/InlineLatex]

If I instead use Mathtran-parser with the code:

The solution(s) to
{{{#!text_x_mathtran scale_factor=3, mathtran_server=http://www.mathtran.org/cgi-bin/toy/
Ax^2+Bx+C=0;
}}}

can be expressed:

{{{#!text_x_mathtran scale_factor=3, mathtran_server=http://www.mathtran.org/cgi-bin/toy/

x =\frac {-B \pm \sqrt { B^2- 4 A C}}{2 A}

}}}

I get the expected result as seen at [http://hpmail.dk/wiki/moin.cgi/Mathtran]

I found the problem: inline_latex sends the complete latex string including $ at the beginning and the end of it to mathtran. Doing

 word = word[1:len(word)-1]

at the beginning of _latex_formula_repl solves the problem.
