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)
|
|
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 tetex-extra 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]

LocalSettings.php changes
OSX Specific installation
Modify the file render.ml to include the full absolute paths to latex, dvips convert etc as follows:
|
|
let cmd_dvips tmpprefix = "/usr/local/teTeX/bin/powerpc-apple-darwin-current/dvips -q -R -E " ^ tmpprefix ^ ".dvi -f >" ^ tmpprefix ^ ".ps"
2 let cmd_latex tmpprefix = "/usr/local/teTeX/bin/powerpc-apple-darwin-current/latex " ^ tmpprefix ^ ".tex >/dev/null"
3 (* Putting -transparent white in converts arguments will sort-of give you transperancy *)
4 let cmd_convert tmpprefix finalpath = "/usr/local/bin/convert -quality 100 -density 120 " ^ tmpprefix ^ ".ps " ^ finalpath ^ " \
>/dev/null 2>/dev/nu ll"
5 (* Putting -bg Transparent in dvipng's arguments will give full-alpha transparency *)
6 (* Note that IE have problems with such PNGs and need an additional javascript snippet *)
7 (* Putting -bg transparent in dvipng's arguments will give binary transparency *)
8 let cmd_dvipng tmpprefix finalpath = "/usr/local/teTeX/bin/powerpc-apple-darwin-current/dvipng -gamma 1.5 -D 120 -T tight --strict " ^ \
tmpprefix ^ ".dvi -o " ^ finalpath ^ " >/dev/null 2>/dev/null"

Now compile texvc with make to create a texvc executable that knows where the locations of the components are.
