"AMCtoOwncloud":https://github.com/remjg/AMCtoOwncloud is a _Nautilus script_ that sends Auto Multiple Choice (AMC) annotated papers to Owncloud/Nextcloud and share them with the corresponding students.

Each quiz file is uploaded to a remote folder unique to each student. Then each folder is:

* _shared with the student_ who can be a local user or a remote user on another federated server

* _shared by link_

Eventually, _shared links are saved_ to a newly created @.csv@ file (default behaviour) or to the current @.csv@ file.

The root folder @Quizzes/@, @Quiz 1@, and @Maths Quizzes@ are configurable, and the other fields come from the `.csv` file.

I use this script to avoid sending emails.

Download the "latest release from github":https://github.com/remjg/AMCtoOwncloud/releases/tag/v0.3.0 and copy @AMCtoOwncloud.sh@ and @.AMCtoOwncloud.py@ in the _Nautilus scripts_ folder: @~/.local/share/nautilus/scripts/@

In order to make it work, you need to install the following Python modules:






    36

    Rémi G.
    






    37
    5
    Rémi G.
    
@requests@, @lxml.html@, @owncloud@ (see "pyocclient":https://github.com/owncloud/pyocclient).

Usually the first are packaged in your distribution. For the @owncloud@ package, I use the following command:

You also need @gnome-terminal@ or you will have to edit the @AMCtoOwncloud.sh@ script file to use another terminal.

The CSV file containing all your student information must use colons @:@ as separators and the following headers (there are optional parameters in method @identify_students()@ to change this behaviour, see [[Special-use-cases]]):

Finally, *annotated papers must contain the student number in their name*

(the first number of the file name is extracted to associate each quiz to the corresponding student). Don't forget to configure @auto-multiple-choice@ using the column headers of your @.csv@ file:

For instance, if your _Owncloud_ server is behind a _Central Authentication Service (CAS)_, you might want to use the parameter @SSO=True@. It has been tested with the Virtual Learning Environment "Envole":https://envole.ac-dijon.fr of a school that use CAS fo authentication.

You can also save shared links to the _current_ @.csv@ file with @replace_csv=True@. Make sure to backup before and be aware that _comment lines starting with a @#@ are lost in the process_.
