Maintained by:

Tri LE

Release 1.3

for Moodle
2.0, 2.1, 2.2, 2.3

This plugin uses JPlag and MOSS as the underlying detection engines to provide an educational tool to raise awareness of students on code plagiarism. It permits:

Quick and easy scanning of assignments
Students' draft submission
Easy report navigation
Multiple scanning and history
Marking pairs of students with possible plagiarism

New version 1.3:

Corrections for reported bugs
Better interface and navigation
Code seeding: upload additional code (e.g. past assignments) to scan with the current assignment

Please take a look at the documentation for screen shoots and more details.

Two quick start video guides could be found at: http://www.screenr.com/Pzl8 and http://www.screenr.com/zfl8.

This plugin was tested with Moodle 2.0 to 2.3. However, it isn't available for use with Moodle 2.4 yet. A fix for compatibility with the latest Moodle version will be released soon.

Hi,
I've noted that this plugin uses yui2 libraries.
Do note that moodle version 2.4 (in development) has moved from using yui2 to yui2in3 as described by MDL-34741.
Here is a link to using yui2in3 : http://yuilibrary.com/yui/docs/yui/yui-yui2.html

Thank you very much. I will switch the remaining YUI 2 to YUI 3. Most of the javascript now use YUI 3 alreay, but some remains in YUI 2 due to lack of time.
If you discover any other things that needs to be corrected, please tell me

Kommentar hinzufügen...I have the same issue:
I have triggered a manual scan (in the submission status – add submission windows).
Then I got a link to the JPlug/MOSS report in the add submission windows.
Following the link I get the following error message: “Invalid course module id”
No report appears.
Thx for checking

It's not working for me either. When I enable the plugin, I then get a blank screen when I try to set up an assignment. Debugging gives:
Fatal error: Cannot redeclare create_file() (previously declared in /home/moodle/public_html/plagiarism/ephorus/lib.php:377) in /home/moodle/public_html/plagiarism/programming/scan_assignment.php on line 90

Ephorus is the other plagiarism plugin we use, for regular text scans comparing with internet sources.

Is this a fatal conflict?

Hi David, yes it is a fatal conflict due to name collision. I will consider changing the name to resolve the conflict and notify you when it is available.
In the mean time, please disable one of the plugin.

Sorry! Temporarily disable it from several day for important bug fixes.

It doesn't seems to work with moodle 2.4.3. The problems are the yui2-libaries. When I try to configure the plugin the system says: "Coding error detected, it must be fixed by a programmer: PAGE->yui2_lib() is not available any more, use YUI 2in3 instead, see MDL-34741 for more information."

May I know there's a release for Moodle2.4+, or a schedule for a new version of the plugin?

Thanks.

Hi Helmond, a new version is under way, and it needs some testing. I hope to finish it at the end of April. Thank you.
