Great question! Since you are working in a Unix-based environment (Ubuntu), understanding how autocrlf input affects your commits is key to keeping your project history clean.
Here is exactly what happens during the commit process:
1. The Conversion Process
When you run git add to stage your changes, Git acts as a filter. If core.autocrlf is set to input:
- Git scans the files you are adding for CRLF (Windows-style) line endings.
- If it finds any, it automatically converts them to LF (Unix-style) before saving them into the Git database.
2. The Result in the Repository
Because of this conversion, the "official" version of the code stored in your repository's history will always use LF.
3. Why is this important?
Imagine a collaborator on a Windows machine sends you a file. Their editor might save it with CRLF. Without this setting, if you committed that file:
- The repository would contain a mix of different line endings.
- Tools that expect Unix endings might malfunction.
- "Diffs" might show every single line as changed just because the hidden line-ending character is different.
In short: autocrlf input ensures that no CRLF characters ever leak into your repository's history, keeping your timeline clean and consistent for all "time travelers" regardless of their operating system
