In the world of version control systems, Git is a widely used tool that keeps track of changes in source code during software development. It allows multiple people to work on a project at the same time without overwriting each other’s changes.
However, as a developer, you may encounter a situation where you only want to view the substantial changes to the code, ignoring minor changes such as those involving whitespace. This post will explain how to achieve this using the
git diff command with the appropriate flags.
git diff command is a powerful tool that can be used to show changes between commits, commit and working tree, etc. This command helps developers understand what changes have been made to the code.
To ignore changes in whitespace while using
git diff, you can use the
--ignore-all-space option. This option treats all white spaces as if they don’t exist while comparing lines. This can be useful when changes in the code are significant, and whitespace changes might cloud the substantial code changes.
Here’s an example of how you can use
git diff to ignore changes in whitespace:
git diff -w OR git diff --ignore-all-space
Additionally, there are other related options you can use:
--ignore-space-at-eol: This ignores changes in whitespace at end of line.
--ignore-space-change (-b): This ignores changes in the amount of whitespace. This treats all consecutive whitespaces as a single whitespace.
--ignore-blank-lines (-B): This option ignores changes that just insert or delete blank lines.
Here’s how you can use these options:
git diff --ignore-space-at-eol git diff -b OR git diff --ignore-space-change git diff -B OR git diff --ignore-blank-lines
Please remember, these commands don’t permanently configure Git to ignore these kinds of changes, they only ignore them for the current command. If you wish to make this a permanent setting for all your
diff commands, you can set the configuration in your git settings like this:
git config --global core.whitespace trailing-space,space-before-tab git config --global diff.ignoreBlankLines true
git diff with the right options can help you better understand the changes to your code by ignoring insignificant changes like whitespace differences.
