介绍

clang-format 位于 clang/tools/clang-format，可用于格式化 C/C++/Java/JavaScript/Objective-C/Protobuf/C# 代码。

$ clang-format -help
OVERVIEW: A tool to format C/C++/Java/JavaScript/JSON/Objective-C/Protobuf/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:

Clang-format options:

  --Werror                   - If set, changes formatting warnings to errors
  --Wno-error=<value>        - If set don't error out on the specified warning type.
    =unknown                 -   If set, unknown format options are only warned about.
                                 This can be used to enable formatting, even if the
                                 configuration contains unknown (newer) options.
                                 Use with caution, as this might lead to dramatically
                                 differing format depending on an option being
                                 supported or not.
  --assume-filename=<string> - Override filename used to determine the language.
                               When reading from stdin, clang-format assumes this
                               filename to determine the language.
  --cursor=<uint>            - The position of the cursor when invoking
                               clang-format from an editor integration
  --dry-run                  - If set, do not actually make the formatting changes
  --dump-config              - Dump configuration options to stdout and exit.
                               Can be used with -style option.
  --fallback-style=<string>  - The name of the predefined style used as a
                               fallback in case clang-format is invoked with
                               -style=file, but can not find the .clang-format
                               file to use.
                               Use -fallback-style=none to skip formatting.
  --ferror-limit=<uint>      - Set the maximum number of clang-format errors to
                               emit before stopping (0 = no limit). Used only
                               with --dry-run or -n
  -i                         - Inplace edit <file>s, if specified.
  --length=<uint>            - Format a range of this length (in bytes).
                               Multiple ranges can be formatted by specifying
                               several -offset and -length pairs.
                               When only a single -offset is specified without
                               -length, clang-format will format up to the end
                               of the file.
                               Can only be used with one input file.
  --lines=<string>           - <start line>:<end line> - format a range of
                               lines (both 1-based).
                               Multiple ranges can be formatted by specifying
                               several -lines arguments.
                               Can't be used with -offset and -length.
                               Can only be used with one input file.
  -n                         - Alias for --dry-run
  --offset=<uint>            - Format a range starting at this byte offset.
                               Multiple ranges can be formatted by specifying
                               several -offset and -length pairs.
                               Can only be used with one input file.
  --output-replacements-xml  - Output replacements as XML.
  --sort-includes            - If set, overrides the include sorting behavior
                               determined by the SortIncludes style flag
  --style=<string>           - Coding style, currently supports:
                                 LLVM, Google, Chromium, Mozilla, WebKit.
                               Use -style=file to load style configuration from
                               .clang-format file located in one of the parent
                               directories of the source file (or current
                               directory for stdin).
                               Use -style="{key: value, ...}" to set specific
                               parameters, e.g.:
                                 -style="{BasedOnStyle: llvm, IndentWidth: 8}"
  --verbose                  - If set, shows the list of processed files

Generic Options:

  --help                     - Display available options (--help-hidden for more)
  --help-list                - Display list of available options (--help-list-hidden for more)
  --version                  - Display the version of this program
