WikiLink is actually two separate things; firstly, a java class for interfacing with a mediawiki server, and secondly, a Mathematica package providing a wrapper around this. This page documents the Mathematica package, whie the java class, and its addition functionality, will be documented elsewhere.

Download

Download WikiLink.zip (file description). Unzip this, probably in the same place you've unzipped the KnotTheory` package. This will create a subdirectory called WikiLink, containing (at least) these files:

Filename	Description
WikiLink.nb	The Mathematica notebook containing wrapper function definitions.
WikiLink.m	The Mathematica package automatically generated from WikiLink.nb.
wikilink.jar	The WikiLink java class and source code (MediawikiConnection.java).
jdom.jar commons-httpclient-3.0-rc2.jar commons-codec-1.3.jar commons-lang-2.1.jar commons-logging.jar	Libraries (all available under either GPL or the Apache license) required by wikilink.jar

Importing the package in Mathematica

First, you'll need to set some paths, so WikiLink` can find the java files it needs.

In[1]:=

KnotAtlasPath = "c:\\scott\\math.berkeley.edu\\Work\\Mathematica\\KnotAtlas\\";

In[2]:=

AppendTo[$Path, KnotAtlasPath];

In[3]:=

SetDirectory[KnotAtlasPath];

In[4]:=

<< "WikiLink\\WikiLink.m"

In[5]:=

SetJarPath[KnotAtlasPath <> "WikiLink\\"];

We then try to connect to the wiki. Executing this line will prompt you for a username and password.

In[6]:=

CreateWikiConnection[ "http://katlas.math.toronto.edu/w/index.php", wikiUserName=InputString["Enter Your Username:"], InputString["Enter Your Password"] ]

The function WikiUserName[] checks that we're logged in

In[7]:= ?WikiUserName WikiUserName[] returns either the name of the user you are logged in as, or $Failed if you appear to be not logged in.

In[8]:=	wikiUserName==WikiUserName[]
Out[8]=	True

Usage

WikiLink` provides only a few functions.

Thus for example and

Compatibility

WikiLink has been tested against mediawiki 1.4.5beta3 and 1.4.7.
