Fork Purger

>> Delete all of your forked repositories on Github <<

Installation

• Install using pip:

  pip install fork-purger
  

Exploration

• Create and collect your Github user access token.

• Inspect the --help menu. Run:

  fork-purger --help
  

  This will print the following:

  +-+-+-+-+ +-+-+-+-+-+-+
  |F|o|r|k| |P|u|r|g|e|r|
  +-+-+-+-+ +-+-+-+-+-+-+
  
  Usage: fork-purger [OPTIONS]
  
  Options:
  --username TEXT       Your Github username.  [required]
  --token TEXT          Your Github access token with delete permission.
                          [required]
  --debug / --no-debug  See full traceback in case of HTTP error.
  --delete              Delete the forked repos.
  --help                Show this message and exit.
  

• By default, fork-purger runs in dry mode and doesn't do anything other than just listing the repositories that are about to be deleted. Run:

  fork-purger --username <gh-username> --token <gh-access-token>
  

  You'll see the following output:

  +-+-+-+-+ +-+-+-+-+-+-+
  |F|o|r|k| |P|u|r|g|e|r|
  +-+-+-+-+ +-+-+-+-+-+-+
  
  These forks will be deleted:
  =============================
  
  https://api.github.com/repos/<gh-username>/ddosify
  https://api.github.com/repos/<gh-username>/delete-github-forks
  https://api.github.com/repos/<gh-username>/dependabot-core
  https://api.github.com/repos/<gh-username>/fork-purger
  

• To delete the listed repositories, run the CLI with the --delete flag:

  fork-purger --username <gh-username> --token <gh-access-token> --delete
  

  The output should look similar to this:

  +-+-+-+-+ +-+-+-+-+-+-+
  |F|o|r|k| |P|u|r|g|e|r|
  +-+-+-+-+ +-+-+-+-+-+-+
  
  Deleting forked repos:
  =======================
  
  Deleting... https://api.github.com/repos/<gh-username>/ddosify
  Deleting... https://api.github.com/repos/<gh-username>/delete-github-forks
  Deleting... https://api.github.com/repos/<gh-username>/dependabot-core
  Deleting... https://api.github.com/repos/<gh-username>/fork-purger
  

• In case of exceptions, if you need more information, you can run the CLI with the --debug flag. This will print out the Python stack trace on the stdout.

  fork-purger --username <gh-username> --token <gh-access-token> --delete --debug
  

Architecture

Internally, fork-purger leverages Python's coroutine objects to collect the URLs of the forked repositories from GitHub and delete them asynchronously. Asyncio coordinates this workflow in a producer-consumer orientation which is choreographed in the orchestrator function. The following diagram can be helpful to understand how the entire workflow operates:

Here, the square boxes are async functions and each one of them is dedicated to carrying out a single task.

In the first step, an async function calls a GitHub GET API to collect the URLs of the forked repositories. The enqueue function then aggregates those URLs and puts them in a queue. The dequeue function pops the URLs from the queue and sends them to multiple worker functions to achieve concurrency. Finally, the worker functions leverage a DELETE API to purge the forked repositories.
