I wanted to get non-recursive raw diff (difftree), but for a given
subdirectory and not starting from root.
I have found '--relative[=<path>]', introduced in
c0cb4a0 (diff --relative: help working in a bare repository, 2008-02-13)
cd676a5 (diff --relative: output paths as relative to the current subdirectory, 2008-02-12)
But when examining it's output in 'raw' mode, I have notice spurious
leading '/' in filename:
$ git diff-tree --abbrev -r --raw HEAD --relative=sub
a3a8425fe5496c61921010cb1e7b455a1f52bb86
:100644 100644 d90bda0... cefcae0... M /quux
The output without '-r' (recurse into sub-trees) is even more strange
$ git diff-tree --abbrev --raw HEAD --relative=sub
a3a8425fe5496c61921010cb1e7b455a1f52bb86
:040000 040000 e62aa6e... b5d4a43... M
(that's a trailing TAB, and no filename).
What I expected was the following output:
$ git diff-tree --abbrev --raw HEAD --relative=sub
a3a8425fe5496c61921010cb1e7b455a1f52bb86
:040000 040000 e62aa6e... b5d4a43... M quux
I see that the '--relative' and '--relative=<path>' options were introduced
for patch ('-p') format, and not for difftree / raw format, but I think
they should work for it, too.
P.S. I have noticed this bug when working on proof-of-concept tree-blame
(i.e. when given file was modified) in Perl.
