NAME
clang-format - manual page for clang-format 3.3
DESCRIPTION
OVERVIEW: A tool to format C/C++/Obj-C code.
If no arguments are specified, it formats the code from standard input and writes the
result to the standard output. If <file>s are given, it reformats the files. If -i is
specified together with <file>s, the files are edited in-place. Otherwise, the result is
written to the standard output.
USAGE: clang-format [options] [<file> ...]
OPTIONS:
-asm-verbose - Add comments to directives.
-bounds-checking-single-trap - Use one trap block per function
-cppfname=<function name> - Specify the name of the generated function
-cppfor=<string> - Specify the name of the thing to generate
-cppgen - Choose what kind of output to generate
=program
- Generate a complete program
=module
- Generate a module definition
=contents
- Generate contents of a module
=function
- Generate a function definition
=functions
- Generate all function definitions
=inline
- Generate an inline function
=variable
- Generate a variable definition

-disable-spill-fusing - Disable fusing of spill code into
instructions
Choose driver interface:
-drvnvcl - Nvidia OpenCL driver
-drvcuda - Nvidia CUDA driver

preserve
-internalize-public-api-list=<list> - A list of symbol names to preserve
