Dear list,

at the moment I am writing a grammar description in which I want to used
quoted string. Up to now I hardcoded the quotes to '"', but now, I want to
enable this rule working with a parameter. Maybe I am missing somethin, I
hope one can give me good hint:

This is the rule definition (for parsing QStrings, I took the code from the
example):

quotedQString %= lexeme[lit(_r1) >> +(char_ - lit(_r1)) >> lit(_r1)];

qi::rule quotedQString;

I am uisng the quotedQString as follows:

nextRule = quotedQString('"') [ anAction(_var,_1)];

This does not work as expected, if I parse a string looking like this
"String" I always got the quotes included. My old version:

quotedQString %= lexeme[lit('"') >> +(char_ - lit('"')) >> lit('"')];

works quite as expected and parses everything without quotes.

 

Kind regards,

 Sven Steckmann
