Detailed Description

Extension point that allows modules to observe and modify an AST build.

One instance is created each time clangd produces a ParsedAST or PrecompiledPreamble. For a given instance, lifecycle methods are always called on a single thread.

Constructor & Destructor Documentation

◆ ~ASTListener()

virtual clang::clangd::FeatureModule::ASTListener::~ASTListener ( )

virtualdefault

Listeners are destroyed once the AST is built.

Member Function Documentation

◆ beforeExecute()

virtual void clang::clangd::FeatureModule::ASTListener::beforeExecute ( CompilerInstance & CI )

inlinevirtual

Called before every AST build, both for main file and preamble.

The call happens immediately before FrontendAction::Execute(), with Preprocessor set up already and after BeginSourceFile() on main file was called.

Definition at line 113 of file FeatureModule.h.

◆ sawDiagnostic()

virtual void clang::clangd::FeatureModule::ASTListener::sawDiagnostic	(	const clang::Diagnostic &	,
		clangd::Diag &
	)

inlinevirtual

Called everytime a diagnostic is encountered.

Modules can use this modify the final diagnostic, or store some information to surface code actions later on.
