Why does "git difftool" not open the tool directly?
There's also an option:
difftool.prompt
Prompt before each invocation of the diff tool.
The following command turns off the prompt globally (for all repos):
git config --global difftool.prompt false
Which is like writing in ~/.gitconfig
:
(or in %HOMEDRIVE%%HOMEPATH%\.gitconfig
)
[difftool]
prompt = false
man git-difftool
OPTIONS
-y, --no-prompt
Do not prompt before launching a diff tool.
