[Flex-help] C++

[Akim D. <ak...@lr...>]

Hi,

I’m happy to see that the C++ code is renovated.  While at it, please
s/struct yy_buffer_state/yy_buffer_state/g, the struct keyword is absolutely
useless, and clutters the flex-lexer.hh file.

Also, really, FLEX_STD is, IMHO, very useless.  Just spread std:: everywhere.
std:: is 17 years old!

Actually, reading the generated code, one reads:

/* The contents of this function are C++ specific, so the () macro is not used.
* This constructor simply maintains backward compatibility.
* DEPRECATED
*/
yyFlexLexer::yyFlexLexer( FLEX_STD istream* arg_yyin, FLEX_STD ostream* arg_yyout ):
	yyin(arg_yyin ? arg_yyin->rdbuf() : std::cin.rdbuf()),
	yyout(arg_yyout ? arg_yyout->rdbuf() : std::cout.rdbuf())
{
	ctor_common();
}

/* The contents of this function are C++ specific, so the () macro is not used.
*/
yyFlexLexer::yyFlexLexer( std::istream& arg_yyin, std::ostream& arg_yyout ):

one has std::, the other has FLEX_STD.  So compliance with std:: is already
assumed.
