Re: [Boost-users] Using boost::format with Lambda expressions

Lambda and format don't play well together, I noticed :( Here's a code that works however, with some explanation. Not pretty.

Best, Jaakko

...

format f("%-10s|") ; for_each(Foos.begin(), Foos.end(), cout << ret(var(f) % bind(&foo::name, _1)));

}

// format defines operator% as a member, which takes precedence over // % defined by lambda. Therefore one must make the format object to // be a lambda functor. var does that. // Var, however, cannot take a temporary object (it holds a reference to // the wrapped object). That's why the variable f. // ret informs lambda about the return type of formats % operator.

OK, that is just what I was looking for, thanks!!! I tried all of those things but not in the right combination. Is there any resources (i.e. example programs or additional documentation) available for the lambda library. I have read through the test code already. Thanks,
