Clang-format is both a library and a stand-alone tool with the goal of automatically reformatting c++ sources files according to configurable style guides. to do so, clang-format uses clang's lexer to transform an input file into a token stream and then changes all the whitespace around those tokens. the goal is for clang-format to both serve both as a user tool (ideally with powerful ide integrations) and part of other refactoring tools, e.g. to do a reformatting of all the lines changed during a renaming.

this package also provides vim and emacs plugins.
