Here's something I discovered recently about !aliases that other folks
might find useful. The canonical form for a shell alias is something
like
git config alias.foo '!echo bar'
where any args given to foo, as in `git foo blah` are passed along to
the shell, so in this case `echo bar blah` would be invoked.
Something that I find very useful is the ability to interpolate
arguments into the middle of a command. This doesn't seem possible at
first glance, not without a helper script. But it certainly is
possible, with the help of shell functions:
git config alias.reverse '!foo () { args=''; while [[ -n "$*" ]];
do args="$1 $args"; shift; done; echo $args; }; foo'
Now if you invoke `git foo one two three` you'll get the response
"three two one".
Here's another example. This one I particularly like. I call it 'send-
patches', because what it does is it takes a single hash and creates
patches out of all commits since that hash, invokes send-mail on them,
and deletes them. It's a rather quick way of sending off patches. And
if you pass any extra arguments, they're given to git-send-email. The
most useful part is it adjusts the patch prefix to contain the name of
the repository itself, so your recipient knows exactly what your patch
is for.
git config --global alias.send-patches '!foo () { rev="$1"; shift;
git send-email $(git format-patch -o .mbox --no-prefix --subject-
prefix="$(printf "PATCH: %s" $(basename $(cd "$(git rev-parse --show-
cdup)" && pwd)))" $rev) "$@"; rm -rf .mbox; }; foo'
