Detailed Description

Utility to run a FrontendAction over a set of files.

This class is written to be usable for command line utilities. By default the class uses ClangSyntaxOnlyAdjuster to modify command line arguments before the arguments are used to run a frontend action. One could install an additional command line arguments adjuster by calling the appendArgumentsAdjuster() method.

Constructor & Destructor Documentation

◆ ClangTool()

clang::tooling::ClangTool::ClangTool ( const CompilationDatabase Compilations,
ArrayRef< std::string >  SourcePaths,
std::shared_ptr< PCHContainerOperations PCHContainerOps = std::make_shared<PCHContainerOperations>(),
IntrusiveRefCntPtr< vfs::FileSystem BaseFS = vfs::getRealFileSystem() 
)

Constructs a clang tool to run over a list of files.

Parameters
CompilationsThe CompilationDatabase which contains the compile command lines for the given source paths.
SourcePathsThe source files to run over. If a source files is not found in Compilations, it is skipped.
PCHContainerOpsThe PCHContainerOperations for loading and creating clang modules.
BaseFSVFS used for all underlying file accesses when running the tool.

Parameters
FilePathThe path at which the content will be mapped.
ContentA null terminated buffer of the file's content.

◆ run()

int clang::tooling::ClangTool::run ( ToolAction Action)

Runs an action over all files specified in the command line.

Parameters
ActionTool action.
Returns
0 on success; 1 if any error occured; 2 if there is no error but some files are skipped due to missing compile commands.
