PyDriller

PyDriller is a Python framework that helps developers in analyzing Git repositories. With PyDriller you can easily extract information about commits, developers, modified files, diffs, and source code.

Install

pip install pydriller

Quick usage

from pydriller import Repository

for commit in Repository('https://github.com/ishepard/pydriller').traverse_commits():
    print(commit.hash)
    print(commit.msg)
    print(commit.author.name)

    for file in commit.modified_files:
        print(file.filename, ' has changed')

Read the docs for more usage examples. Furthermore, a video is available on Youtube.

How to contribute

First clone the repository:

git clone https://github.com/ishepard/pydriller.git
cd pydriller

(Optional) It is suggested to make use of virtualenv. Therefore, before installing the requirements run:

python3 -m venv venv
source venv/bin/activate

Then, install the requirements:

pip install -r requirements.txt

(Important) I tend to not accept Pull Requests without tests, so:

  • unzip the test-repos.zip zip file
  • inside are many "small repositories" that were manually created to test PyDriller. Use one of your choice to test your feature (check the existing tests for inspiration)
  • if none is suitable for testing your feature, create a new one. Be careful: if you create a new one, do not forget to upload a new zip file test-repos.zip that includes your new repository, otherwise the tests will fail.

To run the tests (using pytest):

unzip test-repos.zip
pip install -r test-requirements.txt
pytest
