git range-diff

Compare two commit ranges (e.g. two versions of a branch). More information: https://git-scm.com/docs/git-range-diff.

• Diff the changes of two individual commits:
  git range-diff {{commit_1}}^! {{commit_2}}^!
• Diff the changes of ours and theirs from their common ancestor, e.g. after an interactive rebase:
  git range-diff {{theirs}}...{{ours}}
• Diff the changes of two commit ranges, e.g. to check whether conflicts have been resolved appropriately when rebasing commits from base1 to base2:
  git range-diff {{base1}}..{{rev1}} {{base2}}..{{rev2}}
