I am trying to find all the lines of code within the current git diff
that have been deleted (in the unstaged changes) using the ruby gem grit, i.e. I want to see all the unstaged changes involving deletions. This would be the equivalent of doing git diff -U0 | grep ^-[^-]
in the shell.
So far I have only been able to figure out how to get the diffs between two commits, or get the names of the files that have been changed.
