How to make git diff --ignore-space-change the default

Question

I could probably setup an alias, but it seems like I should be able to set this as an option in the config file, only I don\'t see anyway to do it.

I only want the <

Answer 1

it would be great if this were possible with an option. but an alias works fairly well. here are the relevant lines from my .gitconfig:

[diff]
    tool = mydiff
[difftool "mydiff"]
    cmd = "colordiff -NuBbwi \"$LOCAL\" \"$REMOTE\" | less -R"
[difftool]
    prompt = false
[alias]
    dt = difftool

this assumes using colordiff, which i recommend, giving you an almost exact copy of what git diff would show, with two differences:

1. the --- line in colordiff is colored differently than the same line in git diff (very minor issue)
2. each file is shown one at a time (annoying issue -- anyone know a fix?)

here's my /etc/colordiffrc:

plain=off
newtext=green
oldtext=red
diffstuff=cyan
cvsstuff=red

(colordiff was obtained from brew)
