Subject: Introduction of GpluginLoader Plugin for Git

[-- Attachment #1.1: Type: text/plain, Size: 661 bytes --]

Dear Git Community,
To address the different needs for workflows between community members and developers, I have developed GpluginLoader, a plugin loader for loading plugins based on c/c++ source code, and it is platform independent.
Additionally, I have included several source files to provide APIs for plugins, including functions for retrieving the current repository's README file, profile, and holder, among others. These APIs are encapsulated in the git-plugin-api.c and git-plugin-api.h files.
You can find the GpluginLoader repository here: https://github.com/Tianxiaoxiao1021/GpluginLoader.
Best regards,
Tianxiaoxiao developer team: Tianxiaoxiao1021
