How to change tab width in git diff?

The standard spacing for a tab is 8 characters.

I prefer to view that as 4 characters in my editors and console. I can easily change this default behavior on console with the tabs command:

tabs -4

However, when using git diff or git show it displays in the default 8 character tab whitespace.

How can I get git diff to render tabs as 4 character spaces?

Solution

  • This actually has nothing to do with git diff.

    git diff actually renders a tab, which is later converted by your terminal emulators (for instance, gnome-terminal) to spaces.

    Go to the preference of your terminal emulator to change that setting.

    Also, git may use a pager, so you might want to configure it like that:

    git config --global core.pager 'less -x1,5'
