SameCodeFinder

SameCodeFinder is a static code text scanner which can find the similar or the same code file in a big directory.

Feature

SameCodeFinder could detect the same function in the source code files. The finder could show the Hamming Distacnce between two funcitons.

Find the same code which need to be extract to reuse
Show the Hamming Distance between each soucecode file(Support All kinds of soucecode type)
Show the Hamming Distance between each soucecode function(Support Java and Object-C now)

The below photo show the calculate result of MWPhotoBrowser

The result come from the command

python SameCodeFinder.py ~/Projects/opensource/MWPhotoBrowser/ .m  --max-distance=10 --min-linecount=3 --functions --detail

Install the python implement of SimHash

pip install simhash

Visit A Python Implementation of Simhash Algorithm if you want to know more about the module.

python SameCodeFinder.py [arg0] [arg1]

[arg0]
- Target Directory of files should be scan
[arg1]
- Doc Suffix of files should be scan, eg
  - .m - Object-C file
  - .swift - Swift file
  - .java - Java file
--detail
- show process detail of scan
--functions
- Use Functions as code scan standard
--max-distance=[input]
- max hamming distance to keep, default is 20
--min-linecount=[input]
- for function scan, the function would be ignore if the total line count of the function less than min-linecount
--output=[intput]
- Customize the output file, default is "out.txt"
