Re: Commit-ish shortcut for immediate parent range

Git's commit-ish is very powerful.  I was wondering however, if there was a

 git-diff 3435fdb4c^..3435fdb4c

Thats "git-diff 3435fdb4c^ 3435fdb4c" - diff need pair of things
(one or more might be implied/default), not DAG.

That is - the short range of a particular commit's parent to that commit; like

 git-diff 3435fdb4c!

Or similar.

Or similar. You have to use git-diff-tree, not git-diff as git-diff
uses working tree as second tree if second argument is not given 
(and index as first tree if first argument is not given).

$ git diff-tree -p 3435fdb4c

(-p to show patch instead of "whatchanged" output) shows diff to parent
of commit 3435fdb4c (if commit is merge commit, show nothing; use -m
or -c or --cc then).


By the way 3435fdb4c.. means 3435fdb4c..HEAD, and ..3435fdb4c means
HEAD..3435fdb4c (where HEAD means current branch).
