How to Compare Code Versions in Microcontroller Programming

Recommended Follow 👇 the public account below to learn more embedded knowledge!
Most programmers have used version control tools like SVN, which has a comparison feature that effectively manages different versions of code and allows for version changes to be compared. It is a very useful software tool. Besides this, what other code comparison tools are there? Let’s share some.
As the saying goes: “Three sentences without straying from the profession,” this is also true for the lovely group of programmers. Even when faced with endless programming work, programmers still diligently work hard, dreaming of changing the world with the code they write. To do a good job, one must first sharpen their tools. Every programmer has their own essential programming tools. Next, I will recommend five of the best code comparison tools for programmers.
1. Beyond Compare
Beyond Compare can easily compare the differences between two source code files, highlighting every byte difference in color for easy viewing, supporting various comparison rules.
Beyond Compare selects the best method to highlight differences, allowing text files to be viewed and edited using syntax highlighting and customizable comparison rules, suitable for documents, source code, and HTML.

Diffuse is quite fast in command line, supporting syntax highlighting for languages like C++, Python, Java, XML, etc. It offers visual comparison, which is very intuitive, supporting two-way and three-way comparisons. This means you can compare two or three text files simultaneously using Diffuse.
It supports common version control tools including CVS, Subversion, Git, and Mercurial, allowing you to directly retrieve source code from the version control system for comparison and merging.
3. WinMerge

WinMerge is a file comparison and merging tool that runs on Windows. It allows for easy comparison of multiple document contents, suitable for programmers or anyone who frequently writes documents.
WinMerge compares the contents of two files and highlights the differences, allowing users to quickly identify discrepancies; it also allows the contents of the left file to overwrite the right one directly, or vice versa.
4. Code Compare
