Understanding the Basics of Modifying Open Source Code

What is Open Source?

Open source is a term used to describe software programs that are freely available to anyone to download and modify. These open source programs are written and distributed under a license that permits code changes to be shared freely among software developers. Open source software is made by a community of developers who make the code available for others to view, modify, and share.

Understanding the Basics of Modifying Open Source Code

Modifying open source code can seem daunting at first, but with a basic understanding of programming language and some practice, it can be done quickly and effectively. The first step is understanding the underlying code base. This includes understanding the language, structure, and any included libraries or frameworks. Once you have a grasp of the code base, the process to modify it is relatively straightforward.

  • Create a project: Create a project in the language you are working with. Be sure to keep the project organized by separating files related to different languages or functions.
  • Make a copy: It is important to keep the original, unmodified code intact. Make a copy of the code in its original form, and store it in a safe location. This is important for troubleshooting purposes.
  • Identify the Desired Change: Before editing the code, identify the desired change. This could be related to a single line of code or a more complex design change. Make sure to document the desired changes clearly.
  • Create a Test Plan: Once the changes are identified, create a test plan for each individual change. This should include scenarios that will test the functionality of the desired changes and verify that they are working correctly.
  • Implement Changes: Using your documented changes, implement the code necessary to accommodate the desired modification. Make sure to test the code thoroughly throughout the process.
  • Test the Code: Once the changes are made, it is important to test the code. This includes running the test plan that was previously created, as well as manually testing the code.
  • Document Changes: Once the code modification is complete, it is important to document the changes. This serves both for a reference point in the future, as well as for traceability purposes.

Working with open source code can be a rewarding experience, and a great way to learn more about programming and software development. Modifying code can be tricky, but by following the basic steps outlined above, you can quickly and effectively make modifications to open source code.

Skill 1 – Familiarizing Yourself With the Codebase

One of the most important skills to possess when modifying an open source code is to familiarize with the existing codebase. It’s important to understand the architecture of the codebase and how all the various parts interact with one another in order to make any successful modifications. This can involve spending some time reading the documentations of the project’s file layout, understanding how authentication is coded in and familiarizing yourself with the components of the front end.

Skill 2 – Device a Plan for Modifying the Code

In addition to familiarizing oneself with the codebase, it’s important to have a plan of attack when it comes to making modifications. This plan should include all of the different changes you are making and any additional features you would like to include. Having a plan helps ensure that the changes are organized and that the modifications do not cause any unintentional issues. It also allows a developer to better visualize the modifications and plan how long it will take to complete them.
Finally, it’s important to be familiar with the debugging and testing tools associated with the open source code. Testing tools, such as unit testing and integration testing, help keep the codebase secure and ensure that all the modifications are running as desired. Furthermore, debugging tools can be used to help identify any potential issues with the modified code and quickly diagnose and fix them.
Overall, modifying an open source codebase can be daunting, but with the right skills, it can also be an enjoyable learning experience. Familiarizing yourself with the codebase, having a plan for the modifications, and being familiar with debugging and testing tools are all essential skills for successfully modifying an open source codebase. Understanding these skills can help to make the process of modifying a codebase much easier and reduce the chances of unexpected errors.
