Any way to set vim's colorcolumn in git diff?

Question

In vim, I can use set colorcolumn=80 to highlight the column 80.

I need same functionality in git diff, any way to do this?

You can try using vim (vimdiff) using this command:

git difftool --tool=vimdiff --no-prompt

If this is something you like, you can configure git to always use vim as its difftool and merge tool:

git config --global diff.tool vimdiff
git config --global merge.tool vimdiff
git config --global difftool.prompt false   

Once you're using vimdiff, familiarize yourself with common actions:

]c :        - next difference
[c :        - previous difference
do          - diff obtain
dp          - diff put
zo          - open folded text
zc          - close folded text
:diffupdate - re-scan the files for differences

You'll gain all the niceties of vim (coloring, macros, modal editing) but you'll be in a specialized mode of vim designed for diffs and merges.
