Hallo Sergey,

I just sat down and wanted to create a plugin for clang-format. It seems
pretty easy indeed. However, I can't get clang-format to write to stdout. Can
you give me a hint on how you solved it?

I'm running clang-format with -output-replacements-xml command line flag.
 
What are you doing about the -style option? Are you translating the generic
options into a config file for clang-format, or are you just ignoring it?

It's lame, but I use a preference page separate from C/C++ > Code Style Formatter that allows user to specify the style. Another option would be to define a separate formatter extension for each of the styles. This way a user wiuld select not just clang-format, but something like clang-format -style=LLVM or clang-format -style=Chromium.

Please keep in mind that clang-format operates in terms of utf-8 byte offsets, not in terms of characters like Eclipse. To avoid bad results on files containing non-ascii characters you have to convert from character offsets to byte offsets and back.

thx Michi
