This is pretty much just a copy of the widely used clang-format-diff.py from the official clang-format svn.
The only adjustment necessary was to fail when no .clang-format file is found:
- if args.style:
- command.extend(['-style', args.style])
+ command.extend(['-style=file', '-fallback-style=none'])
You can use it by just piping a diff:
git diff -U0 HEAD~1.. | ./contrib/devtools/clang-format-diff.py -p1 -i -v

Use /usr/bin/env python instead of /usr/bin/python.
On operating systems like the BSDs, it is typically the case that
/usr/bin/python does not exist. We should therefore use /usr/bin/env
instead. This is also done in various other scripts in tools/.

clang-format-diff.py: fix -regex/-iregex matching
While debating the finer points of file extension matching, we somehow missed
the bigger problem that the current code will match anything starting with the
default or user-specified pattern (e.g. lit.site.cfg.in).
Fix this by doing what find(1) does, implicitly wrapping the pattern with ^$.

Added -iregex for case-insensitive regex to filter file names.
Summary:
-regex and -iregex both mimic options of the find utility.
Made the default list of extensions case-insensitive, so that it's not only C
and CPP extensions are accepted in upper case.

clang-format-diff.py: Support -regex filter and more filename extensions
Add support for more filename extensions based on the list in the clang
plus JavaScript.
Also adds a -regex option so users can override defaults if they have unusual
file extensions or want to format everything in the diff.
Keeping with tradition the flag is modelled on Unix conventions, this time
matching the semantics of find(1).

Changed clang-format-diff.py to output diff by default. Added -i option to apply changes to files instead.
Summary:
"svn diff|clang-format-diff.py" will just output the diff.
Now it's possible to use:
svn diff|clang-format-diff.py|patch -p0
as an equivalent to:
svn diff|clang-format-diff.py -i
;)

clang-format: Don't exit with failure on empty files.
Also let clang-format-diff.py detect errors based on clang-format's
return code. Otherwise messages like "Can't find usable .clang-format,
falling back to LLVM style" can make it fail, which might be undesired.

clang-format: Fix clang-format-diff.py according to diff specification.
Patch by Alp Toker. Many thanks!
Original descriptions:
clang-format-diff incorrectly modifies unchanged lines due to an error
in diff parsing.
The unified diff format has a default line change count of 1, and 0 may
be specified to indicate that no lines have been added. This patch
updates the parser to accurately reflect the diff specification.
This also has the benefit of stabilising the operation so it will
produce the same output when run multiple times on the same changeset,
which was previously not the case.
No tests added because this script is not currently tested (though we
should look into that!)
