Enabling math markup
Organic Design procedure
|
|
Use this procedure to add math rendering support which is not included in the install a new server procedure by default as it requires many additional program libraries (about 200MB worth)
|
|
As of MediaWiki version 1.18 the math rendering has been put into the Math extension. See MW:Manual:Math for more details. To download the latest version of the extensions, use:
Note that as of MediaWiki 1.19, the extension repository has become out of sync with the codebase and a specific version needs to be used which you can download from [1].
Build the texvc binary
Enabling math markup requires latex, dvips, gs, and convert. OCaml 3.06 or later from caml.inria.fr is required to compile texvc. On Debian-based systems the requirements can be installed with the following packages:
|
|
apt-get install dvipng cjk-latex ocaml
|
|
- Run make from within the MediaWiki's math directory to build the texvc binary on your system.
- Make sure the directories tmp and math under 'images' exist and are writable.
Example
The following maths code
|
|
<math>
e^x = \sum_{n = 0}^{\infty} {x^n \over n!} = 1 + x + {x^2 \over 2!} + {x^3 \over 3!} + {x^4 \over 4!} + \cdots
</math>
|
|
Should give the following output
|
|
[math]e^x = \sum_{n = 0}^{\infty} {x^n \over n!} = 1 + x + {x^2 \over 2!} + {x^3 \over 3!} + {x^4 \over 4!} + \cdots[/math]
