clang-format - manual page for clang-format 14
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
--files=<string> - Provide a list of files to run
clang-format
-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.
--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
- --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=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-list-hidden for more)
--version - Display the version of this program
