Math

[killerfrog]

Hi everyone,

I'm trying to get math works

If I write :

{{ math.formula("\\alpha^2+\\beta^2*\\gamma^3=1") }}

it does work, but if I write something just a little more complicated, it gives me error :

{{ math.formula("\[\sum\limits_{i = \infty } {\frac{{e^i }}{{ i^i }}}\]") }}

returns :

La fonction math.formula a échoué en renvoyant:

latex failed with status 1:

ligne 1, colonne 14: ")" expectedligne 1, colonne 2: EOF expected}\]") }}

To prove there is no error in what I wrote (except this has absolutely no meaning in maths), here it is : http://ohara00.homeftp.net:8080/cgi-...}{{i^i%20}}}\]

What's wrong ?

Thank you

The problem comes the inner }}, which the parser mistakes for the end of the dekiscript expression.

Try the following.
1) switch to HTML mode
2) find the {{ math.formula("\[\sum\limits_{i = \infty } {\frac{{e^i }}{{ i^i }}}\]") }} text
3) replace it with <pre class="script">math.formula("\[\sum\limits_{i = \infty } {\frac{{e^i }}{{ i^i }}}\]")</pre>

This removes the reliance on {{ }} parsing and should fix your issue.

Alternatively, you can try using spaces between the inner }} double curly braces, like } }. But I don't know if that will change the rendering of your formula.

ish that's not very userfriendly.

Would there be a way for activating it a little bit like BBcodes under phpBB3 (see the post i've done there on this subject).

example :

[tex] f(x)=\int_{-\infty}^xe^{-t^2}dt [/tex]

The way it's supposed to work is that you created a "formatted" area using styles, then you type in your formula, click on "transform content" and select "math.formula".

1.9.0 missed the mark on that, sadly. It only has syntax transforms.

that will be a great feature. Let just wait then.
