How to alter context ("unified") on `git difftool`?

Question

I tried -U9("--unified") and git config --global diff.context - it affects only git diff but neither git difftool (I prefer vimdiff) nor git commit -p (commit by hunks).

Answer 1

Add this into .vimrc: :set diffopt=filler,context:9

Also you can toggle fold:

The command zc will close a fold (if the cursor is in an open fold), and zo will open a fold. It's easier to just use za which will toggle the current fold (close it if it was open, or open it if it was closed). Source: https://vim.wikia.com/wiki/Folding
