git staging no whitespace

Question

I know about interactive staging (from a GUI point of view at least) and I know how to ignore whitespace changes in git diff with git diff -w.

I'm using git-cola at the moment and there is the option to hide whitespace changes on the diff view but then interactive staging doesn't work anymore.

Is there a way to do interactive staging (line by line) while ignoring whitespace changes? If I have to go back to command line that's not an issue.

Answer 1

Turns out this is just not possible in git-cola at least.
