NAME
clang-tidy - manual page for clang-tidy 6.0
DESCRIPTION
USAGE: clang-tidy [options] <source0> [... <sourceN>]
OPTIONS:
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
clang-tidy options:
-analyze-temporary-dtors -
Enable temporary destructor-aware analysis in clang-analyzer- checks. This option
overrides the value read from a .clang-tidy file.
-checks=<string> -
Comma-separated list of globs with optional '-' prefix. Globs are processed in
order of appearance in the list. Globs without '-' prefix add checks with matching
names to the set, globs with the '-' prefix remove checks with matching names from
the set of enabled checks. This option's value is appended to the value of the
'Checks' option in .clang-tidy file, if any.
-config=<string> -
Specifies a configuration in YAML/JSON format:
-config="{Checks: '*',
CheckOptions: [{key: x,
value: y}]}"
When the value is empty, clang-tidy will attempt to find a file named .clang-tidy
for each source file in its parent directories.
-dump-config -
Dumps configuration in the YAML format to stdout. This option can be used along
with a file name (and '--' if the file is outside of a project with configured
compilation database). The configuration used for this file will be printed. Use
along with -checks=* to include configuration of all checks.
-enable-check-profile -
Enable per-check timing profiles, and print a report to stderr.
-explain-config -
For each enabled check explains, where it is enabled, i.e. in clang-tidy binary,
command line or a specific configuration file.
-export-fixes=<filename> -
YAML file to store suggested fixes in. The stored fixes can be applied to the input
source code with clang-apply-replacements.
-extra-arg=<string> - Additional argument to append to the compiler command line
-extra-arg-before=<string> - Additional argument to prepend to the compiler command line
-fix -
Apply suggested fixes. Without -fix-errors clang-tidy will bail out if any
compilation errors were found.
-fix-errors -
Apply suggested fixes even if compilation errors were found. If compiler errors
have attached fix-its, clang-tidy will apply them as well.
-format-style=<string> -
Style for formatting code around applied fixes:
- 'none' (default) turns off formatting
- 'file' (literally 'file', not a placeholder)
uses .clang-format file in the closest parent
directory
- '{ <json> }' specifies options inline, e.g.
-format-style='{BasedOnStyle: llvm, IndentWidth: 8}'
- 'llvm', 'google', 'webkit', 'mozilla'
See clang-format documentation for the up-to-date information about formatting
styles and options. This option overrides the 'FormatStyle` option in .clang-tidy
file, if any.
-header-filter=<string> -
Regular expression matching the names of the headers to output diagnostics from.
Diagnostics from the main file of each translation unit are always displayed. Can
be used together with -line-filter. This option overrides the 'HeaderFilter'
option in .clang-tidy file, if any.
-line-filter=<string> -
List of files with line ranges to filter the warnings. Can be used together with
-header-filter. The format of the list is a JSON array of objects:
[ {"name":"file1.cpp","lines":[[1,3],[5,7]]}, {"name":"file2.h"}
]
-list-checks -
List all enabled checks and exit. Use with -checks=* to list all available checks.
-p=<string> - Build path
-quiet -
Run clang-tidy in quiet mode. This suppresses printing statistics about ignored
warnings and warnings treated as errors if the respective options are specified.
-system-headers - Display the errors from system headers.
-warnings-as-errors=<string> -
Upgrades warnings to errors. Same format as '-checks'. This option's value is
appended to the value of the 'WarningsAsErrors' option in .clang-tidy file, if any.
-p <build-path> is used to read a compile command database.
For example, it can be a CMake build directory in which a file named
compile_commands.json exists (use -DCMAKE_EXPORT_COMPILE_COMMANDS=ON CMake option
to get this output). When no build path is specified, a search for
compile_commands.json will be attempted through all parent paths of the first input
file . See: http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html for an example
of setting up Clang Tooling on a source tree.
<source0> ... specify the paths of source files. These paths are
looked up in the compile command database. If the path of a file is absolute, it
needs to point into CMake's source tree. If the path is relative, the current
working directory needs to be in the CMake source tree and the file must be in a
subdirectory of the current working directory. "./" prefixes in the relative files
will be automatically removed, but the rest of a relative path must be a suffix of
a path in the compile command database.
Configuration files:
clang-tidy attempts to read configuration for each source file from a .clang-tidy
file located in the closest parent directory of the source file. If any
configuration options have a corresponding command-line option, command-line option
takes precedence. The effective configuration can be inspected using -dump-config:
$ clang-tidy -dump-config

Checks:
'-*,some-check'
WarningsAsErrors: '' HeaderFilterRegex: '' AnalyzeTemporaryDtors: false
FormatStyle: none User: user CheckOptions:
- key: some-check.SomeOption
