git diffall, open all diff files immediatly (eg tabbed window in BC)

[Seba Illingworth]

I came up with the following 'git-diffall' script to open all diff files
immediately, rather than default behavior of opening them one at a 
time in serial.

    for name in $(git diff --name-only $1); do git difftool $1 $name & done

I blogged the details at 
http://blog.codefarm.co.nz/2009/08/git-diff-and-difftool-open-all-files.html

You must have difftool.prompt (or mergetool.prompt) set to
false, otherwise git would be prompting you during the loop.

To make it work irrespective of the configuration, pass
--no-prompt or -y to difftool.


Also maybe something like:

for name in "$(git diff --name-only "$@")"; do
	git difftool "$@" "$name" &
done

The quotes should make it work paths that have spaces.
The "$@" should let you pass arbitrary parameters to difftool.

Have fun,

One last note (I promise ;)):

I would recommend against saying 'git difftool head' on your
blog beause that only works on OSX with its case-preserving yet
case-insensitive filesystem.  It might be worth mentioning that.

If you try 'git diff head' on a different filesystem (for
example, if you tried it on Linux) you'll find that it doesn't
work because the file is .git/HEAD; .git/head doesn't exist.

On OSX the filesystem tells git that .git/head exists even
though it's actually finding .git/HEAD.

Thanks David, understood and updated to 'HEAD'. 'head' had worked for me with my 
sloppy Windows ways ;)

I struggled with your previous suggestion for handling paths with spaces; 
I couldn't get the for-loop to split the input into individual filenames
on the line-break separator (after outer quotes expanded the result?).

But rewriting it this way seems to work well and handles spaces (Windows):

    git diff --name-only "$@" | while read filename; do
        git difftool "$@" --no-prompt "$filename" &
    done

Hope you can comment on this variation? 
And thanks for all the tips! Seba
