# Tools for developing Git

## Summary

This document gathers tips, scripts and configuration file to help people working on Git’s codebase use their favorite tools while following Git’s coding style.

### Author

The Git community.

## Table of contents

- Visual Studio Code (VS Code)

- Emacs

### Visual Studio Code (VS Code)

The contrib/vscode/init.sh script creates configuration files that enable several valuable VS Code features. See contrib/vscode/README.md for more information on using the script.

### Emacs

This is adapted from Linux’s suggestion in its CodingStyle document:

- To follow rules of the CodingGuideline, it’s useful to put the following in GIT_CHECKOUT/.dir-locals.el, assuming you use cperl-mode:

    ;; note the first part is useful for C editing, too
    ((nil . ((indent-tabs-mode . t)
             (tab-width . 8)
             (fill-column . 80)))
             (cperl-mode . ((cperl-indent-level . 8)
                            (cperl-extra-newline-before-brace . nil)
                            (cperl-merge-trailing-else . t))))

For a more complete setup, since Git’s codebase uses a coding style similar to the Linux kernel’s style, tips given in Linux’s CodingStyle document can be applied here too.
