Detailed Description

Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.

A ClangTidyCheck always has access to the active context to report warnings like:

Context->Diag(Loc, "Single-argument constructors must be explicit")
<< FixItHint::CreateInsertion(Loc, "explicit ");

Definition at line 104 of file ClangTidyDiagnosticConsumer.h.

Constructor & Destructor Documentation

◆ ClangTidyContext()

ClangTidyContext::ClangTidyContext ( std::unique_ptr< ClangTidyOptionsProvider OptionsProvider)

Initializes ClangTidyContext instance.

Definition at line 178 of file ClangTidyDiagnosticConsumer.cpp.

References setCurrentFile(), and ~ClangTidyContext().

◆ ~ClangTidyContext()

ClangTidyContext::~ClangTidyContext ( )
default

Referenced by ClangTidyContext().

Member Function Documentation

◆ clearErrors()

void clang::tidy::ClangTidyContext::clearErrors ( )
inline

Clears collected errors.

Definition at line 170 of file ClangTidyDiagnosticConsumer.h.

◆ diag()

DiagnosticBuilder ClangTidyContext::diag ( StringRef  CheckName,
SourceLocation  Loc,
StringRef  Message,
DiagnosticIDs::Level  Level = DiagnosticIDs::Warning 
)

Report any errors detected using this method.

This is still under heavy development and will likely change towards using tablegen'd diagnostic IDs. FIXME: Figure out a way to manage ID spaces.

Definition at line 189 of file ClangTidyDiagnosticConsumer.cpp.

◆ getCheckName()

StringRef ClangTidyContext::getCheckName ( unsigned  DiagnosticID) const

Returns the name of the clang-tidy check which produced this diagnostic ID.

Definition at line 252 of file ClangTidyDiagnosticConsumer.cpp.

◆ getCheckProfileData()

ProfileData* clang::tidy::ClangTidyContext::getCheckProfileData ( ) const
inline

Definition at line 177 of file ClangTidyDiagnosticConsumer.h.

◆ getCurrentBuildDirectory()

const std::string& clang::tidy::ClangTidyContext::getCurrentBuildDirectory ( )
inline

Returns build directory of the current translation unit.

Definition at line 185 of file ClangTidyDiagnosticConsumer.h.

Referenced by clang::tidy::ClangTidyDiagnosticConsumer::HandleDiagnostic().

◆ getCurrentFile()

StringRef clang::tidy::ClangTidyContext::getCurrentFile ( ) const
inline

Returns the main file name of the current translation unit.

◆ getErrors()

ArrayRef<ClangTidyError> clang::tidy::ClangTidyContext::getErrors ( ) const
inline

Returns all collected errors.

◆ getGlobalOptions()

const ClangTidyGlobalOptions & ClangTidyContext::getGlobalOptions ( ) const

Returns global options.

Referenced by clang::tidy::ClangTidyCheck::getLangOpts(), and clang::tidy::ClangTidyDiagnosticConsumer::HandleDiagnostic().

◆ getOptions()

const ClangTidyOptions & ClangTidyContext::getOptions ( ) const

Returns options for CurrentFile.

The CurrentFile can be changed using setCurrentFile.

Definition at line 224 of file ClangTidyDiagnosticConsumer.cpp.

Referenced by clang::tidy::ClangTidyDiagnosticConsumer::HandleDiagnostic(), and setCurrentFile().

◆ getOptionsForFile()

ClangTidyOptions ClangTidyContext::getOptionsForFile ( StringRef  File) const

Returns options for File.

Does not change or depend on CurrentFile.

Definition at line 164 of file ClangTidyDiagnosticConsumer.h.

◆ isCheckEnabled()

bool ClangTidyContext::isCheckEnabled ( StringRef  CheckName) const

Returns true if the check is enabled for the CurrentFile.

The CurrentFile can be changed using setCurrentFile.
