NAME¶

clang-format - manual page for clang-format 11

DESCRIPTION¶

OVERVIEW: A tool to format C/C++/Java/JavaScript/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

--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, GNU, Google, Chromium, Microsoft, 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
