Which language is used in Git?

Git is primarily written in C, with some parts implemented in Perl, Shell, and other scripting languages. Here's a breakdown of the languages used in Git's development:

1. Primary Language

• C: Git's core functionality, such as version control operations (e.g., commits, merges, and diffs), is implemented in C. This choice allows Git to be lightweight, fast, and efficient across various platforms.

2. Supporting Languages

• Perl: Early on, Perl was used for scripting some auxiliary functions in Git. Over time, many of these have been rewritten in C or Shell.
• Shell: Shell scripting is used for parts of Git’s functionality, especially for platform-specific configurations and commands.
• Python and Tcl: Used occasionally for test scripts or specific tool integrations.

Why C Was Chosen

• Performance: C provides high execution speed and low-level control over system resources, which is essential for Git's file system operations.
• Portability: C code can be compiled and run on virtually any operating system, making Git widely compatible.

Git's choice of C as its core language is one reason it is known for being a fast and reliable version control system.
