How to Use Git Configuration Based on Subdirectory Names

by | Feb 3, 2023 | Miscellaneous | 0 comments

Git is a powerful tool that allows developers to manage source code and track changes over time. One of the lesser-known features of Git is its ability to read different configuration files based on the name of a subdirectory. This feature can be useful if you work on multiple projects with different configurations.

In this post, we’ll show you how to use an if-else statement to read different Git configuration files based on the name of a subdirectory.

Step-by-Step Guide

Follow these steps to use Git configuration based on subdirectory names:

  • Create a .gitconfig file in your home directory if it doesn’t already exist.
  • Add the following lines to the file:

[includeIf "gitdir:*/my-subdirectory/"]
  path = ~/.gitconfig-my-subdirectory

This tells Git to include the ~/.gitconfig-my-subdirectory file if the current repository is located in the my-subdirectory subdirectory.

  • Create a ~/.gitconfig-my-subdirectory file with the specific configuration settings for repositories in that subdirectory.
  • Optionally, you can another includeif statement to include a different configuration file for all other repositories that are not located in the my-subdirectory subdirectory. For example:

[includeIf "gitdir:*/my-subdirectory/"]
  path = ~/.gitconfig-my-subdirectory
[includeIf "gitdir:*"]
  path = ~/.gitconfig-default

This includes the ~/.gitconfig-default file for all repositories that are not located in the my-subdirectory subdirectory.

Note that the gitdir: pattern matches against the absolute path of the .git directory, so you need to use * as a wildcard to match any subdirectories.

Conclusion

In this post, we showed you how to use Git configuration based on subdirectory names. By using different configuration files for different projects, you can streamline your development process and avoid mistakes caused by using the wrong configuration settings.
