Detailed Description

Implementation of the ClangTidyOptionsProvider interface, which tries to find a configuration file in the closest parent directory of each source file.

By default, files named ".clang-tidy" will be considered, and the clang::tidy::parseConfiguration function will be used for parsing, but a custom set of configuration file names and parsing functions can be specified using the appropriate constructor.

Constructor & Destructor Documentation

FileOptionsProvider() [1/2]

clang::tidy::FileOptionsProvider::FileOptionsProvider	(	ClangTidyGlobalOptions	GlobalOptions,
		ClangTidyOptions	DefaultOptions,
		ClangTidyOptions	OverrideOptions,
		llvm::IntrusiveRefCntPtr< llvm::vfs::FileSystem >	FS = nullptr
	)

Initializes the FileOptionsProvider instance.

Parameters

GlobalOptions	are just stored and returned to the caller of getGlobalOptions.
DefaultOptions	are used for all settings not specified in a configuration file.

If any of the

Parameters

OverrideOptions

fields are set, they will override whatever options are read from the configuration file.

Definition at line 376 of file ClangTidyOptions.cpp.

FileOptionsProvider() [2/2]

clang::tidy::FileOptionsProvider::FileOptionsProvider	(	ClangTidyGlobalOptions	GlobalOptions,
		ClangTidyOptions	DefaultOptions,
		ClangTidyOptions	OverrideOptions,
		FileOptionsBaseProvider::ConfigFileHandlers	ConfigHandlers
	)

Initializes the FileOptionsProvider instance with a custom set of configuration file handlers.

Parameters

GlobalOptions	are just stored and returned to the caller of getGlobalOptions.
DefaultOptions	are used for all settings not specified in a configuration file.

If any of the

Parameters

OverrideOptions	fields are set, they will override whatever options are read from the configuration file.
ConfigHandlers	specifies a custom set of configuration file handlers. Each handler is a pair of configuration file name and a function that can parse configuration from this file type. The configuration files in each directory are searched for in the order of appearance in ConfigHandlers.
