NAME

clang-format - manual page for clang-format 14

DESCRIPTION

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.
configuration contains unknown (newer) options. Use with caution, as this might lead to dramatically differing format depending on an option being supported or not.
When reading from stdin, clang-format assumes this filename to determine the language.
clang-format from an editor integration

--dry-run - If set, do not actually make the formatting changes

Can be used with -style option.
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

--files=<string> - Provide a list of files to run clang-format

-i - Inplace edit <file>s, if specified.

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 (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

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.

--qualifier-alignment=<string> - If set, overrides the qualifier alignment style determined by the QualifierAlignment style flag

--sort-includes - If set, overrides the include sorting behavior determined by the SortIncludes style flag

LLVM, GNU, Google, Chromium, Microsoft, Mozilla, WebKit.
.clang-format file located in one of the parent directories of the source file (or current directory for stdin). Use -style=file:<format_file_path> to explicitly specifythe configuration file. 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
