Re: [Boost-users] [Property Tree] Latest version and CVS

Hi Chris, Un-customized ptree uses (string, string) pairs to hold data. If you are using sandbox-cvs version (i.e. the latest one), it is easy to customize data type to be boost::any. There's even a working example on how to do that in libs/property_tree/examples/custom_data_type.cpp. Once you do that, you can then manually associate types with values. As for associating types with a values read from a file, I don't see any easy way to do it. How would the parser determine the type of the value that it reads in?

Marcin, I have looked at the documentation a little bit, and I have a few questions. It is not clear in the documentation if the implementation uses (std::string,boost::any) pairs, but I recall reading something about that being the case. With that set up it seems values inserted in the tree, programmatically, could have type information, but values read from a file could only be string types. I am interested in typing properties read in from a file. Is there a way to associate types with values read from a file. If not that is fine, I can always check if the type is a string and use lexical_cast. Chris

Hi Chris,

The latest version is always in boost-sandbox CVS. You can access that anonymously - see instructions at http://boost.org/more/mailing_lists.htm#sandbox. Sandbox version is much improved over what is in boost vault (which is the version used for review), but the documentation is yet lagging behind, so you might encounter a couple of surprises. The good news is that the basic interface and usage have not changed.

Marcin

Hi, I am interested in using the new Property Tree library, and I was wondering where I can get the latest version. Chris
