Detailed Description

template<typename PPTy = PrettyPrinter>
class circt::pretty::TokenStream< PPTy >

Wrap a PrettyPrinter with TokenBuilder features as well as operator<<'s.

String behavior: Strings streamed as const char * are assumed to have external storage, and StringRef's are saved until no longer needed. Use PPExtString() and PPSaveString() wrappers to specify/override behavior.

Constructor & Destructor Documentation

◆ TokenStream()

template<typename PPTy = PrettyPrinter>

circt::pretty::TokenStream< PPTy >::TokenStream	(	PPTy &	pp,
		TokenStringSaver &	saver )

inline

Create a TokenStream using the specified PrettyPrinter and StringSaver storage.

Strings are saved in saver, which is generally the listener in the PrettyPrinter, but may not be (e.g., using BufferingPP).

◆ addAsString()

template<typename PPTy = PrettyPrinter>

template<typename T>

TokenStream & circt::pretty::TokenStream< PPTy >::addAsString ( T && t )

template<typename Callable, unsigned BufferLen = 128>

auto circt::pretty::TokenStream< PPTy >::invokeWithStringOS ( Callable && c )

Helper to invoke code with a llvm::raw_ostream argument for compatibility.

All data is gathered into a single string token.
