The no_skip[]
directive turns off white space skipping. The difference to lexeme is that it does not do
pre-skipping in any case. Otherwise it is completely equivalent to the
lexeme
directive.

Some using declarations:

Simple usage of no_skip[]:
The use of no_skip here will prevent skipping of whitespace in front
and in between the characters of the string '
abc '.
std::string str; test_phrase_parser_attr("' abc '", '\'' >> no_skip[+~char_('\'')] >> '\'', str); std::cout << str << std::endl; // will output: > abc <
