But I cannot figure out the right way of doing this. The natural:
const bool result = boost::spirit::qi::parse(it,str.end(),int_
repeat(_1)[ char_ ]);
fails to compile (and I tried many variations of val, etc) with no success. If I replace _1 by 10, everything works fine.
_1 doesn't makes sense here, it's only for use in semantic action, e.g. `int_[_a = _1]`.
Ah OK. I did not realize that. Maybe it should be better explained in the documentation. On the other hand, it would be nice if it had worked.... less surprising.
Another question is that of the associated attribute. From the
documentation, I would have expected it to be:
typedef std::pair<int,std::vector<unsigned char>> Attribute;
but that does not work. I have managed to work around this using a second rule, using an attribute std::vector<char>(int) but then again I do not know how to pass the parameter. 10 works but _1 does not.
perhaps you need to include the Fusion header that adapts std::pair.
Indeed I forgot that one, and I knew it (using it elsewhere).
Any help will be appreciated. Some test code is attached, compile with: g++ -g -std=c++11 -dboost_spirit_use_phoenix_v3 Test.C. Variants are in comment.
A working version is attached.
Thank's it helped me, even though I cannot really use it in this form (in particular the local variable do not fit as my rule is split in severeal ones. But it helped me design a solution (going through a variable local to the method). Again thank's a lot. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlRHckEACgkQEr8WrU8nPV1ZlwCfQ5dGpT7kmMBzAn2P0HRsBiJk 5DAAn3IYz5GlrLQ4UglMRgop3RoQSeGi =OoJQ -----END PGP SIGNATURE-----
