texvc had several tasks in the past: 1 checking the input 2 convert MediaWiki custom syntax to standard LaTeX 3 run LaTeX 4 convert dvi2png This change provides a simplified version that performs only steps 1+2. This is required to avoid security problems with tools like MathJax, especially if these tools are run at the server-side. Bug: 54624 Change-Id: I1650e6ec2ccefff6335fbc36bbe8ca8f59db0faa

== About texvccheck ==
|
|
|
|
texvc takes the user input validates it and replaces MediaWiki specific functions.
|
|
Input data is parsed and scrutinized for safety.
|
|
|
|
texvc was written by Tomasz Wegrzanowski for use with MediaWiki; it's
|
|
included as part of the MediaWiki package (http://www.mediawiki.org) and is
|
|
under the GPL license.
|
|
|
|
texvc-lite, was extracted from the original texvc program in 2013 by
|
|
Moritz Schubotz and uses only the sanitizing and customization part.
|
|
|
|
The list of all commands can be viewed by browsing the source files.
|
|
Most commands are listed at
|
|
http://sdrv.ms/15w2gVw
|
|
there is also a tool for convenient whitelisting of special commands
|
|
that are used in local wikis.
|
|
|
|
Please report bugs at: https://bugzilla.wikimedia.org/
|
|
with "MediaWiki extensions" as product and "Math" as component.
|
|
|
|
== Setup ==
|
|
|
|
=== Requirements ===
|
|
|
|
OCaml 3.06 or later is required to compile texvc; this can be acquired from
|
|
http://caml.inria.fr/ if your system doesn't have it available.
|
|
|
|
The makefile requires GNU make.
|
|
|
|
In Ubuntu Precise, all dependencies can be installed using:
|
|
|
|
$ sudo apt-get install ocaml
|
|
|
|
=== Installation ===
|
|
|
|
Run 'make' (or 'gmake' if GNU make is not your default make). This should
|
|
produce the texvccheck executable.
|
|
|
|
By default,
|
|
MediaWiki will search in this directory for texvc, if you moved it elsewhere,
|
|
you'll have to modify $wgTexvc and set it to the path of the texvc executable.
|
|
|
|
== Usage ==
|
|
|
|
Normally texvc is called from MediaWiki's Math modules and everything
|
|
Just Works. It can be run manually for testing or for use in another app.
|
|
|
|
=== Command-line parameters ===
|
|
|
|
texvccheck '\TeX input string'
|
|
|
|
Be sure to properly quote the TeX code!
|
|
|
|
Example:
|
|
|
|
texvc "y=x+2"
|
|
|
|
=== Output format ===
|
|
|
|
The output is the sanitized and customized tex string.
|
|
|
|
texvc output format is like this:
|
|
+%s ok
|
|
S syntax error
|
|
E lexing error
|
|
F%s unknown function %s
|
|
- other error
|
|
|
|
== Hacking ==
|
|
|
|
Before you start hacking on the math package its good to know the workflow,
|
|
which is basically:
|
|
|
|
1. texvc gets called by Math/Math.body.php (check out the line begining with "$cmd")
|
|
2. texvc does its magic, which is basically to check for invalid latex code.
|
|
3. texvc takes the user input validates it and replaces MediaWiki specific functions
