d2lmf 1.0.0

Motivation
It’s frustrating dealing with the zip files full of assignment
submissions that you get from D2L.

Merging all of a student’s submissions into a single folder is
tedious.
Navigating submissions on the command line sucks, because each
directory name starts with a long number.
Extracting all the zip files, tar archives, and 7z archives that
students submit adds a needless extra step to marking.

I’ve found this tool useful for eliminating those annoyances, and I hope
you will too.

How to Use
This is the most common command I use:
d2lmf extract -R "Assignment 1 Download Oct 11, 2015 803 PM.zip" A1/T01
It extracts the submissions from the zip folder into the directory
A1/T01. The -R option makes it run all the recommended cleanup
actions on the submissions, and is equivalent to using -x, -j,
-c and -m.
The -x specifies that we want to extract any zip, rar, tar, or 7z
archives that students submitted. The -j deletes ‘junk’ like
.DS_Store. The -c collapses needlessly nested directories.
Finally, the -m merges all submitted files into a single directory
for each student.
On Windows, you may need to invoke d2lmf as a Python module, like so:
python -m d2lmf extract -R "Assignment 1 Download Oct 11, 2015 803 PM.zip" A1/T01

How to Install

Ubuntu
sudo apt-get install python-pip
sudo pip install d2lmf

OSX
curl https://bootstrap.pypa.io/get-pip.py > get-pip.py
sudo python get-pip.py
sudo pip install d2lmf

Windows
First, download and install Python from
https://www.python.org/downloads/
Then, install d2lmf with the command below:
python -m pip install d2lmf

Dependencies
The extraction of rar and 7z archives depends on external tools. If you
do not have a rar or 7z utility installed, those archives will be
skipped.
On Windows, I suggest installing 7-Zip. On
Ubuntu, p7zip is the equivalent, and it can be installed with
sudo apt-get install p7zip-full. p7zip is also available for OSX,
and can be installed from homebrew with
brew install p7zip.
