Release status: unmaintained
|Description||Shows Wolfram CDF files in wiki pages.|
|Latest version||0.2.1 (Goodge Street) (2012-04-25)|
|MediaWiki||1.18+ (requires 'position' support in ResourceLoader)|
|License||GNU General Public License 3.0 or later|
Allows Wolfram CDF files (interactive content generated by Wolfram Mathematica) to be shown in wiki pages.
The basic syntax for the cdf extension is:
<cdf width="width in pixels" height="height in pixels">filename</cdf>
When specifying the filename, you do not need to include the `File:` namespace in the filename - it will work with or without it. If enabled, you may also provide an absolute URL instead of a filename to show a CDF file from another server.
<cdf width="650" height="400">SomeExample.cdf</cdf> <cdf width="565" height="589">http://demonstrations.wolfram.com/HobermanCube/HobermanCube.cdf</cdf>
Note that the second example above will only work if
$wgCDFAllowExternalURLs is set to
true; the default is to not show external URLs.
Download instructions edit
To download the extension, you may obtain a zip of the latest code from the download link in the infobox. Alternatively, you may clone the git repository with the following command:
git clone git://github.com/TheWatcher/wolfram_cdf.git
To install this extension, place the wolfram_cdf directory in your extensions directory, and add the following to LocalSettings.php:
Note that, in order to actually upload and use .cdf files, you will need to ensure that file uploads are enabled (
true) and cdf extensions are allowed. For example:
$wgEnableUploads = true; $wgUseImageMagick = true; $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'txt', 'cdf' );
You may also need to either ensure that your webserver serves up .cdf files as
application/x-netcdf or, if that is not possible, you may need to modify
$IP/includes/mime.types to contain
text/plain txt cdf
This should only be done in exceptional circumstances, however!
The following parameters can be set in the LocalSettings.php file:
- If this is set to
true(the default is
false) then <cdf> tags may contain URLs to load .cdf files from other web servers. This should be enabled with caution, as it may have security implications!
- If set to
true(the default is
false), the extension will place a 'Click here to download this CDF' link beneath each CDF box to allow users to save a copy of the CDF for offline use.
For example, your LocalSettings.php file may contain:
require_once("$IP/extensions/wolfram_cdf/CDF.php"); $wgCDFAllowExternalURLs = false; $wgCDFShowDownloadLink = true;
The following css classes can also be used to apply styling to the html generated by this extension:
- Each CDF box is contained within a div with this class
true, the CDF download link is placed in a div with this class.
