Subject: Undocumented git-diff syntax
Date: Mon, 11 Oct 2010 15:03:42 +0200 [thread overview]
Message-ID: <20101011150342.292ad725@chalon.bertin.fr> (raw)
When trying "just to see it it would work", I noticed that the
following syntax appears to do what it looks like it should do.
git diff v1.7.3-rc0:Documentation/RelNotes-1.7.3.txt v1.7.3:Documentation/RelNotes/1.7.3.txt
It is a useful thing, but I could not find described in the manpage. I have not dig this
part of diff yet, and maybe someone would have already a description of it (does it simply allow
to diff two arbitrary blobs ?). Is it here just by some magic side-effect ? :)
Another thought: if we can already compare arbitrary blobs, maybe it would not be so hard to
extend it to take arbitrary contents that are not stored as blobs yet ? (a quick hack would be to
insert an object for them, but that does not look too clean...). As a use-case, I'm often found generating diffs from within custom scripts, from contents derived from a git repo, but can't use all the bells and whistles (--color, --color-words, etc), just because I have to use plain diff;
that makes the output of those scripts very inconsistent with native git commands.
Would there be any objections to moving into that direction ?
