◆ doCoverageCheck()

std::error_code ModularizeUtilities::doCoverageCheck	(	std::vector< std::string > &	IncludePaths,
		llvm::ArrayRef< std::string >	CommandLine
	)

Do coverage checks.

For each loaded module map, do header coverage check. 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.

Parameters

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.

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.

Definition at line 113 of file ModularizeUtilities.cpp.

◆ getCanonicalPath()

std::string ModularizeUtilities::getCanonicalPath ( llvm::StringRef FilePath )

static

Convert header path to canonical form.

The canonical form is basically just use forward slashes, and remove "./".
