Getting contributors for each file using git shortlog in Python subprocesses is a handy way to analyze the authors of code changes in a Git repository. In this tutorial, I'll walk you through the steps to achieve this, including explanations and code examples. We will use the subprocess module in Python to execute Git commands.
Before we begin, make sure you have the following:
We will start by importing the subprocess module, which allows us to run Git commands from our Python script.
Next, let's create a Python function that will use the git shortlog command to get the contributors for each file in your repository.
In this function:
We change the working directory to the provided Git repository path using os.chdir() so that all Git commands run in the correct context.
We use the git log command with options to get the commit history, including the list of files changed in each commit. We then split the output into individual commits.
For each commit, we extract the commit hash and author information, and for each changed file, we add the author to the list of contributors for that file in the file_contributors dictionary.
You can now run the get_contributors_for_each_file function by providing the path to your Git repository as an argument. Here's an example:
Replace '/path/to/your/git/repository' with the actual path to your Git repository. When you run this script, it will print the contributors for each file in your repository.
This tutorial demonstrated how to get contributors for each file in a Git repository using the git shortlog command and Python's subprocess module. You can further modify the code to save the results to a file or integrate it into your own Git analysis tools.
