GSoC 2020 Suppression Patch Filter Report

https://github.com/checkstyle/checkstyle/wiki/Checkstyle-GSoC-2020-Project-Ideas#project-name-patch-suppression

Description: Introducing Checkstyle to a project can be a challenging and NOT an easy job, especially when a project has massive amount of code, very active in development, and there are no resources to start a new process of code cleanup. Checkstyle needs a new approach for filtering violations, which should be based on the diff details of the last commit. With this, users will only need to fix violations only in newly created or changed code. It could be configurable to skip changed lines and and only show violations in purely new code.

What I learn and harvest from GSoC 2020

1. GSoC enables me to understand how to participate in the contribution of an open source community, familiarize myself with Git tools, and make me more confident to write better code.

2. Through the patch-filters, I really realize that Test-driven development (TDD) is a meaningful software development process. patch-filters practices this approach and TDD is the core and driving force of this project.
