git diff output colors

Question

I am using a command that opens the git diff output of the selected file in a menu. however the output in the menu is not colored as opposed to normal diff output in terminal. Using git diff --color also doesn't help.

command! Gdiff git diff %c %m

Answer 1

That's expected. Menus don't yet parse escape sequences like quick preview or view mode. They weren't updated to do that after introducing corresponding parser. It's not trivial when it comes to horizontal scrolling, searching and highlighting of search results on top of handling UTF-8 data, but is doable since it works in view mode.
