ClangFormat Diff Reformatter

"""
|
||||
This script reads input from a unified diff and reformats all the changed
|
||||
lines. This is useful to reformat all the lines touched by a specific patch.
|
||||
Example usage for git/svn users:
|
||||
|
||||
git diff -U0 --no-color HEAD^ | clang-format-diff.py -p1 -i
|
||||
svn diff --diff-cmd=diff -x-U0 | clang-format-diff.py -i
|
||||
git diff -U0 --no-color --relative HEAD^ | {clang_format_diff} -p1 -i
|
||||
svn diff --diff-cmd=diff -x-U0 | {clang_format_diff} -i
|
||||
|
||||
It should be noted that the filename contained in the diff is used unmodified
|
||||
to determine the source file to update. Users calling this script directly
|
||||
should be careful to ensure that the path in the diff is correct relative to the
|
||||
current working directory.
