boost spirit + boost bind, la galére

**Sahengette** · 06/07/2012, 11h47

Bonjour,
je suis en blocage complet sur boost spirit,j'essaye de lancer une fonction membre d'un objet quand une régle est parsé :

Code :

struct ArgGrammar : qi::grammar<std::string::iterator, qi::blank_type>
{
	ArgGrammar(Arguments & O) : ArgGrammar::base_type(start)
	{	
		using qi::float_;
		using qi::uint_;
		using qi::char_;
		using qi::eol;
		using qi::eps;
		using qi::blank;
		using namespace boost;
 
		param = "\""  >> *(char_[push_back(phoenix::ref(paramb), qi::_1)] - "\"") >> "\"" >> 
		eps[bind(&Arguments::maFunc, O, qi::_1)("un parametre de type string")];
 
		start = *(l | d | a | i);
	}	
 
	qi::rule<std::string::iterator, qi::blank_type> start, l, d, a, i, param, hour;
	std::string paramb;
	float hd, md, ha, ma;
};

Donc j'aimerais que lorsqu'il parse la régle param, il lance la fonction membre tel que O.maFunc("un parametre de type string"), seulement ca ne fonctionne pas, avez vous une idée du fonctionnement de bind avec spirit pour les fonctions membre, sachant que le paramétre est fixe (ne dépend pas de ce que je parse).

Merci de votre attention à mon post.

Bonjour,

Pourquoi tu passes pas un placeholder (qi::_1) si tu lui donne le paramètre juste après ? Ta fonction a un effet de bord ?

**Sahengette** · 06/07/2012, 13h56

sincérement, je ne sais pas, en lisant la doc je vois toujours ce placeholder, et j'avoue que je n'arrive pas trés bien à suivre la logique de spirit et bind.

voici l'erreur avec ce code :

Regardes la doc de boost::bind, les exemples aident à comprendre.

Tu ne m'as pas dit si ta fonction avaient des effets de bord ? Elle fait quoi exactement ?

Tu pourrais faire voir la signature de la fonction membre que tu veux utiliser ?

**Sahengette** · 06/07/2012, 14h52

Cette fonction n'a pas vraiment d'effet de bord, en fonction de l'état interne de l'objet, elle remplit le bon tableau de ce même objet.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

void Arguments::newArg(std::string na)

**Flob90** · 06/07/2012, 15h25

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

boost::bind(&Arguments::newArg, boost::ref(O), "une chaine")

**Sahengette** · 07/07/2012, 13h12

J'ai essayé ces trois formules, et les trois me sortent une erreur, si j'enlève l'epsilon ca compile

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

param = "\""  >> *(char_[push_back(phoenix::ref(paramb), _1)] - "\"") >> "\"" >> eps[&Arguments::newArg, O, "test"];

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

param = "\""  >> *(char_[push_back(phoenix::ref(paramb), _1)] - "\"") >> "\"" >> eps[&Arguments::newArg, boost::ref(O), "test"];

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

param = "\""  >> *(char_[push_back(phoenix::ref(paramb), _1)] - "\"") >> "\"" >> eps[&Arguments::newArg, phoenix::ref(O), "test"];

je ne peux pas vous rapporter l'erreur de compilation, developpez n'acceptant "que" 60 000 caractéres, le message en faisant 170 000

**Flob90** · 07/07/2012, 13h29

Tu as oublié d'écrire boost::bind.

**Sahengette** · 07/07/2012, 13h53

C'est bizarre, ca marche mieux tout d'un coup

.
Merci, de m'avoir fait gagner du temps par cette aprés-midi chaude, qui m'a carrément zombifié le cerveau

boost spirit + boost bind, la galére

Boost C++

Vue hybride
