Test Math Formula HTML

The first test were disappointing. It seems no mathematical formulas work with Creole.

Neither the mediawiki HTML format

{{math|{{radical|1 − ''e''²}}}}

Nor the TEX format

<math> f(x) = x^2\,\!</math>

Nor MathML

 <math xmlns="http://www.w3.org/1998/Math/MathML">
    <mo> &int; </mo>
    <mn> 0 </mn>
    <mn> 1 </mn>
    <msqrt><mi> x </mi></msqrt>
    <mo> &InvisibleTimes; </mo>
     <mo> &DifferentialD; </mo>
     <mi> x </mi>

Although I created a macro that is capable to display this, but it is not convenient to read.

0 1 x x

An other example.

<math xmlns="http://www.w3.org/1998/Math/MathML">
 <mi mathvariant="double-struck">C</mi>

Is rendered as

17+29i C

And finally

<math xmlns="http://www.w3.org/1998/Math/MathML">

As I decided to implement matplotlib anyway, I opted for MathtextBackend. Unfortunately this is poorly documented. Although a tutorial and an extended example is available, no examples cover how it is used with web applications.

I learned from this webpage how to provide matplotlib graphics from a web server. An idea how to integrate matplotlib into django I found here.

This leaves us with two options how to implement matplotlib graphics

  1. by calling a view with the urlencoded TEX formula.
  2. by storing a temporary image that has to be destroyed after its use.

some formula

The implementation is explained here.
