Detailed Description

Module map checker class.

This is the heart of the checker. The doChecks function does the main work. The data members store the options and internally collected data.

Constructor & Destructor Documentation

◆ CoverageChecker()

CoverageChecker::CoverageChecker	(	llvm::StringRef	ModuleMapPath,
		std::vector< std::string > &	IncludePaths,
		llvm::ArrayRef< std::string >	CommandLine,
		clang::ModuleMap *	ModuleMap
	)

Constructor.

You can use the static createCoverageChecker to create an instance of this object.

Parameters

ModuleMapPath	The module.modulemap file path. Can be relative or absolute.
IncludePaths	The include paths to check for files. (Note that other directories above these paths are ignored. To expect all files to be accounted for from the module.modulemap file directory on down, leave this empty.)
CommandLine	Compile command line arguments.
ModuleMap	The module map to check.

Member Function Documentation

◆ collectFileSystemHeaders() [1/2]

bool CoverageChecker::collectFileSystemHeaders ( )

Collect file system header files.

This function scans the file system for header files, starting at the directory of the module.modulemap file, optionally filtering out all but the files covered by the include path options.

Returns: True if no errors.

◆ collectFileSystemHeaders() [2/2]

bool Modularize::CoverageChecker::collectFileSystemHeaders ( llvm::StringRef IncludePath )

Collect file system header files from the given path.

This function scans the file system for header files, starting at the given directory, which is assumed to be relative to the directory of the module.modulemap file.

Returns: True if no errors.

◆ collectModuleHeaders() [1/2]

void CoverageChecker::collectModuleHeaders ( )

Collect module headers.

Walks the modules and collects referenced headers into ModuleMapHeadersSet.

◆ collectModuleHeaders() [2/2]

bool Modularize::CoverageChecker::collectModuleHeaders ( const clang::Module & Mod )

Collect referenced headers from one module.

Collects the headers referenced in the given module into ModuleMapHeadersSet.

Parameters

Mod	The module reference.

Returns: True if no errors.

◆ collectUmbrellaHeaderHeader()

void CoverageChecker::collectUmbrellaHeaderHeader ( llvm::StringRef HeaderName )

Called from CoverageCheckerCallbacks to track a header included from an umbrella header.

Parameters

HeaderName The header file path.

◆ collectUmbrellaHeaderHeaders()

bool CoverageChecker::collectUmbrellaHeaderHeaders ( llvm::StringRef UmbrellaHeaderName )

Collect headers referenced from an umbrella file.

Parameters

UmbrellaHeaderName The umbrella file path.

Returns: True if no errors.

Definition at line 273 of file CoverageChecker.cpp.

◆ collectUmbrellaHeaders()

bool CoverageChecker::collectUmbrellaHeaders ( llvm::StringRef UmbrellaDirName )

Collect headers from an umbrella directory.

Parameters

UmbrellaDirName The umbrella directory name.

Returns: True if no errors.

		clang::ModuleMap *	ModuleMap
	)

static

Create instance of CoverageChecker.

Parameters

ModuleMapPath	The module.modulemap file path. Can be relative or absolute.
IncludePaths	The include paths to check for files. (Note that other directories above these paths are ignored. To expect all files to be accounted for from the module.modulemap file directory on down, leave this empty.)
CommandLine	Compile command line arguments.
ModuleMap	The module map to check.

Returns: Initialized CoverageChecker object.

◆ doChecks()

std::error_code CoverageChecker::doChecks ( )

Do checks.

Starting from the directory of the module.modulemap file, Find all header files, optionally looking only at files covered by the include path options, and compare against the headers referenced by the module.modulemap file. Display warnings for unaccounted-for header files.

Returns: 0 if there were no errors or warnings, 1 if there were warnings, 2 if any other problem, such as a bad module map path argument was specified.

◆ findUnaccountedForHeaders()

void CoverageChecker::findUnaccountedForHeaders ( )

Find headers unaccounted-for in module map.

This function compares the list of collected header files against those referenced in the module map. Display warnings for unaccounted-for header files. Save unaccounted-for file list for possible. fixing action.
