#(B)randeis (A)nti-(P)lagiarism (T)ool ##Introduction This tool is using MOSS from Standford University as plagiarsim detection engine and developed by Wenbin Xiao to automatically unpack archive files(recursively if necessary), pre-process submissions then submit to MOSS with configuration.

##Prerequisite

• Python 2.x
• moss please go to MOSS website to apply for the submission script and follow the installation. When you have your moss, put it under the same directory of bapt.

##Usage

bapt -l lang [-b basefiles] -d dir1 [dir2, dir3, ...]

• -l to specify the postfix of the language
• -b optional, to specify the basefiles directory
• -d to specify the directories containing files or archives

##How it works BAPT will go through directories specified by -d:

• If there is an archive file, it creates a directory based on the archive name, then extract files in the archive to that directory; it only extracts files with extension specified by -l option. Extraction is recursive, it means files in sub-archives inside that archive will also be extracted.
• If there is a directory, it will recursively "flatten" the directory such that all files in sub-directories will be moved out to the directory and then sub-directories will be removed.

After preprocessing all files, it will upload them along with basefiles(if the basefile directory is specified by -b) to MOSS.

##Example

###Basic Assuming you have a directory source_dir as following:

source_dir/
├── Alice.tar
│   ├── nested-archive.tar
│   │   ├── file11.java
│   │   └── file12.java
│   ├── file1.java
│   └── file2.java
└── Bob.tar
│   ├── file1.java
│   └── file2.java
└── James/
    ├── sub-dir/
    │   └── file11.java
    ├── file1.java
    └── file2.java

If you run command like:

bapt -l java -b basefiles -d source_dir

After pre-processing, it becomes:

source_dir/
├── Alice/
│   ├── file1.java
│   ├── file11.java
│   ├── file12.java
│   └── file2.java
└── Bob/
│   ├── file1.java
│   └── file2.java
└── James/
    ├── file1.java
    ├── file11.java
    └── file2.java

And then all java files will be submitted to MOSS.

###Multiple Directories You can also submit multiple directories. It can be easily achieved by specifying multiple directories for -d. Example:

bapt -l java -b basefiles -d source_dir/2013 source_dir/2014

This is useful when you want to check assignment solutions from different classes.
