How To Set Important Git Config Global Properties?

Git is a powerful version control system that allows you to manage and track changes in your projects. Configuring Git properly is essential for an efficient and effective workflow. This article will cover how to set some of the most important global configuration properties in Git to optimize your setup.

Why Configure Git?

Configuring Git ensures that your preferences and settings are applied consistently across all your repositories. This includes setting your identity, preferred text editor, the default behaviour for line endings, and more. Configuring these properties globally saves time and helps prevent common issues.

Setting Global Configuration Properties

1. User Information

Setting your name and email address is crucial because Git includes this information in each commit. This allows others to know who made changes and how to contact them if necessary.

Set Your Name:

git config --global user.name "Your Name"

Set Your Email:

git config --global user.email "[email protected]"

2. Default Text Editor

When Git requires you to enter a commit message or resolve merge conflicts, it opens a text editor. You can configure which text editor Git uses.

Set the Default Text Editor (e.g., VS Code):

git config --global core.editor "code --wait"

Other common editors:

• Vim: git config --global core.editor "vim"
• Nano: git config --global core.editor "nano"
• Sublime Text: git config --global core.editor "subl -n -w"

3. Line Ending Handling

Different operating systems handle line endings differently. Configuring Git to manage line endings correctly can prevent issues when collaborating across different systems.

Set Line Ending Conversion (for Windows):

git config --global core.autocrlf true

For macOS and Linux, you may want to disable automatic conversion:

git config --global core.autocrlf input

4. Merge Tool

Setting a default merge tool helps you resolve merge conflicts more easily.

Set the Default Merge Tool (e.g., KDiff3):

git config --global merge.tool kdiff3

To set VS Code as the merge tool:

git config --global merge.tool code
git config --global mergetool.code.cmd "code --wait $MERGED"

5. Color Settings

Enabling color can make Git output easier to read.

Enable Colored Output:

git config --global color.ui auto

6. Credential Helper

Managing credentials can be tedious. Configuring a credential helper can simplify authentication for remote repositories.

Set Credential Helper (e.g., Cache for macOS and Linux):

git config --global credential.helper cache

For Windows:

git config --global credential.helper wincred

For macOS:

git config --global credential.helper osxkeychain

7. Aliases

Git aliases can save you time by creating shortcuts for frequently used commands.

Set Common Aliases

git config --global alias.st status
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit

Applying and Verifying Configurations

After setting your global configuration properties, you can verify them using the following command:

git config --global --list

This command will list all the global configurations you have set.
