Definition at line 48 of file HeaderIncludes.h.

◆ JSONCommandLineSyntax

A JSON based compilation database.

JSON compilation database files must contain a list of JSON objects which provide the command lines in the attributes 'directory', 'command', 'arguments' and 'file': [ { "directory": "<working directory of the compile>", "command": "<compile command line>", "file": "<path to source file>" }, { "directory": "<working directory of the compile>", "arguments": ["<raw>", "<command>" "<line>" "<parameters>"], "file": "<path to source file>" }, ... ] Each object entry defines one compile action. The specified file is considered to be the main source file for the translation unit.

'command' is a full command line that will be unescaped.

'arguments' is a list of command line arguments that will not be unescaped.

JSON compilation databases can for example be generated in CMake projects by setting the flag -DCMAKE_EXPORT_COMPILE_COMMANDS.

◆ addExpandedResponseFiles()

void clang::tooling::addExpandedResponseFiles ( std::vector< std::string > &  CommandLine,
llvm::StringRef  WorkingDir,
llvm::cl::TokenizerCallback  Tokenizer,
llvm::vfs::FileSystem &  FS 
)

Helper function that expands response files in command line.

Definition at line 308 of file Tooling.cpp.

◆ addTargetAndModeForProgramName()

void clang::tooling::addTargetAndModeForProgramName ( std::vector< std::string > &  CommandLine,
StringRef  InvokedAs 
)

Changes CommandLine to contain implicit flags that would have been defined had the compiler driver been invoked through the path InvokedAs.

For example, when called with InvokedAs set to i686-linux-android-g++, the arguments '-target', 'i686-linux-android,–driver-mode=g++` will be inserted after the first argument in CommandLine.

This function will not add new -target or --driver-mode flags if they are already present in CommandLine (even if they have different settings than would have been inserted).

Precondition
llvm::InitializeAllTargets() has been called.
Parameters
CommandLinethe command line used to invoke the compiler driver or Clang tool, including the path to the executable as CommandLine[0].
InvokedAsthe path to the driver used to infer implicit flags.
Note
This will not set CommandLine[0] to InvokedAs. The tooling infrastructure expects that CommandLine[0] is a tool path relative to which the builtin headers can be found.

◆ applyAllReplacements() [2/2]

llvm::Expected< std::string > clang::tooling::applyAllReplacements ( StringRef  Code,
const Replacements Replaces 
)

Applies all replacements in Replaces to Code.

This completely ignores the path stored in each replacement. If all replacements are applied successfully, this returns the code with replacements applied; otherwise, an llvm::Error carrying llvm::StringError is returned (the Error message can be converted to string using llvm::toString() and 'std::error_codein theError` should be ignored).

const ApplyChangesSpec Spec 
)

Applies all AtomicChanges in Changes to the Code.

This completely ignores the file path in each change and replaces them with FilePath, i.e. callers are responsible for ensuring all changes are for the same file.

Returns
The changed code if all changes are applied successfully; otherwise, an llvm::Error carrying llvm::StringError is returned (the Error message can be converted to string with llvm::toString() and the error_code should be ignored).

)

This creates a ToolExecutor that is in the global registry based on commandline arguments.

This picks the right executor based on the --executor option. This parses the commandline arguments with CommonOptionsParser, so caller does not need to parse again.

By default, this creates a StandaloneToolExecutor ("standalone") if --executor is not provided.

◆ createRefactoringActionRule()

template<typename RuleType , typename... RequirementTypes>
std::unique_ptr< RefactoringActionRule > clang::tooling::createRefactoringActionRule ( const RequirementTypes &...  Requirements)

Creates a new refactoring action rule that constructs and invokes the RuleType rule when all of the requirements are satisfied.

This function takes in a list of values whose type derives from RefactoringActionRuleRequirement. These values describe the initiation requirements that have to be satisfied by the refactoring engine before the provided action rule can be constructed and invoked. The engine verifies that the requirements are satisfied by evaluating them (using the 'evaluate' member function) and checking that the results don't contain any errors. Once all requirements are satisfied, the provided refactoring rule is constructed by passing in the values returned by the requirements' evaluate functions as arguments to the constructor. The rule is then invoked immediately after construction.

The separation of requirements, their evaluation and the invocation of the refactoring action rule allows the refactoring clients to:

  • Disable refactoring action rules whose requirements are not supported.
  • Gather the set of options and define a command-line / visual interface that allows users to input these options without ever invoking the action.

Definition at line 118 of file RefactoringActionRulesInternal.h.

◆ createRefactoringActions()

std::vector< std::unique_ptr< RefactoringAction > > clang::tooling::createRefactoringActions ( )

◆ createRefactoringOption()

template<typename OptionType >
std::shared_ptr< OptionType > clang::tooling::createRefactoringOption ( )

Constructs a refactoring option of the given type.

The ownership of options is shared among requirements that use it because one option can be used by multiple rules in a refactoring action.

References clang::File.

◆ getAbsolutePath() [2/2]

std::string clang::tooling::getAbsolutePath ( StringRef  File)

Returns the absolute path of File, by prepending it with the current directory if File is not absolute.

Otherwise returns File. If 'File' starts with "./", the returned path will not contain the "./". Otherwise, the returned path will contain the literal path-concatenation of the current directory and File.

The difference to llvm::sys::fs::make_absolute is the canonicalization this does by removing "./" and computing native paths.

Parameters
FileEither an absolute or relative path.

◆ replaceNestedName()

std::string clang::tooling::replaceNestedName ( const NestedNameSpecifier Use,
SourceLocation  UseLoc,
const DeclContext UseContext,
const NamedDecl FromDecl,
StringRef  ReplacementString 
)

Emulate a lookup to replace one nested name specifier with another using as few additional namespace qualifications as possible.

This does not perform a full C++ lookup so ADL will not work.

Parameters
UseThe nested name to be replaced.
UseLocThe location of name to be replaced.
UseContextThe context in which the nested name is contained. This will be used to minimize namespace qualifications.
FromDeclThe declaration to which the nested name points.
ReplacementStringThe replacement nested name. Must be fully qualified including a leading "::".
Returns
The new name to be inserted in place of the current nested name.
