Space skip parser doesn't skip trailing spaces

[olafvdspek@…]

#include <cassert>

#include <boost/spirit/include/classic.hpp>

using namespace BOOST_SPIRIT_CLASSIC_NS;

int main()
{
    parse_info<> result = parse(" 5 ", int_p, space_p);
    assert(result.full);
    return 0;
}

AFAIK, parser should skip spaces until reaching the int, and should consume while reading the int and stop after that. So, it should not skip trailing spaces in this case.

AFAIK, parser should

Why?

Guys, please see ​http://spirit.sourceforge.net/ and the note in red titled: Post-skips

[OlafvdSpek@…]

I don't agree with that work around, but it should at least be mentioned in the Spirit documentation and examples.

Feel free to voice out your objection to spirit's mailing list. FWIW, the new spirit2 has some defaults that does post skipping and a flag parameter to disable it. Unfortunately, we do not intend to change the behavior for "classic" spirit anymore since it is now in maintenance mode. But then again, I urge you to voice out your concern if you really need to. In the meantime, I'll be closing this ticket.

What about this part?

[Joel de Guzman]

Noted. Please add a trac ticket for this.

[OlafvdSpek@…]

Eh, this *is* a trac ticket, isn't it?

[Joel de Guzman]

Yes, but it is the wrong ticket. You want documentation and examples, not bug fixing. It is better to have another "support" related trac ticket asking exactly what you want. Otherwise, this will flag the wrong message.

Done: ​https://svn.boost.org/trac/boost/ticket/3099

It would be way easier if existing reports could just be reassigned...

Thank you.
