CLANG-FORMAT(1)

NAME
clang-format - manual page for clang-format 19

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>] [<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>     - Set filename used to determine the language and to find
    .clang-format file. Only used when reading from stdin. If this is not passed, the .clang-format file is searched relative to the current working directory when reading stdin. Unrecognized filenames are treated as C++. supported:

CSharp: .cs
    Java: .java JavaScript: .mjs .js .ts Json: .json Objective-C: .m .mm Proto: .proto .protodevel TableGen: .td TextProto: .txtpb .textpb .pb.txt .textproto .asciipb Verilog: .sv .svh .v .vh

--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.

--fail-on-incomplete-format - If set, fail with exit code 1 on incomplete format.

--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. Defaults to 'LLVM'. 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=<filename> - A file containing a list of files to process, one per line.

-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>               - Set coding style. <string> can be:
    1. A preset: LLVM, GNU, Google, Chromium, Microsoft,

Mozilla, WebKit.
    2. 'file' to load style configuration from a

.clang-format file in one of the parent directories
    of the source file (for stdin, see --assume-filename). If no .clang-format file is found, falls back to --fallback-style. --style=file is the default.

3. 'file:<format_file_path>' to explicitly specify
    the configuration file.

4. "{key: value, ...}" to set specific parameters, e.g.:
    --style="{BasedOnStyle: llvm, IndentWidth: 8}"

--verbose - If set, shows the list of processed files
