New Revision: 300891
URL: http://llvm.org/viewvc/llvm-project?rev=300891&view=rev
Log:
Begin making git-clang-format python3 compatible.
This patch fixes most of the python3 incompatabilities
within git-clang-format while keeping the script python2 compatible.
There is still one remaining incompatability that prevents using Python3
which is the `str` vs `byte` type change. I plan to put those fixes
up for review separately.
This patch contains fixes for the following incompatabilities:
1) Use the new style Python3 `print` function. This requires importing
__future__.print_function.
2) Fix incompatability between the Python3 octal prefix and the
octal prefix Git uses.
3) Replace use of dict.iteritems() with dict.viewitems() because iteritems()
has been removed in Python3. viewitems() reviews python 2.7 but that is
also what the script is documented as requiring.
