Detailed Description

Implements tracing support for the parser.

Constructor & Destructor Documentation

Puma::Tracing::Tracing ( )

inlineprotected

Constructor.

Member Function Documentation

ostream& Puma::Tracing::tos ( ) const

protected

Get the tracing output stream.

void Puma::Tracing::trace	(	ostream &	os,
		bool	trace_tokens = false
	)

Setup the tracer.

Parameters

os	The output stream on which to write the tracing output.
trace_tokens	Turn on/off token level tracing.

void Puma::Tracing::trace ( int  token )

inlineprotected

Trace the given token.

Parameters

token

The token type.

void Puma::Tracing::trace ( const char *  rule, int  n = 1, bool  quote = false  )

protected

Trace the given parser rule.

Parameters

rule	The rule name.
n	The indentation depth.
quote	Quote the rule name.

void Puma::Tracing::trace ( Token *  token, const char *  ok, const char *  failed  )

protected

Trace the given token.

Parameters

token	The token to trace.
ok	The message if the token is not NULL.
failed	The message if the token is NULL.

int Puma::Tracing::trace_mode ( ) const

inlineprotected

Get the current tracing mode.

0 means tracing is disabled, 1 means rule level tracing, 2 means token level tracing.
