Ben Craig commented on THRIFT-2717:
-----------------------------------

Most of the features mentioned in the ticket don't require C\+\+11.  Here are 
the features that require (or at least sort-of require) C\+\+11.

* unordered map/sets
This could be addressed with boost::unordered instead.  Ideally, we make it so 
that we can switch to std in an environment 
* returning using move semantics, no more ugly 'return via output parameter' 
(still possible as option thou - sometimes it's needed for performance)
This can be done with C++98, and with optimizations, it is usually as 
efficient.  Still, this can be addressed by generating a second interface for 
each service that implements the return approach, instead of the out-param 
approach.
* enum classes
* initializer lists for constants (maybe)
These would be nice, but I don't know if they justify the confusion, testing, 
and maintenance burden of another generator

So -0.9.  I really don't like this, but I'm not going to stand in the way if 
everyone else wants to go ahead with it.

> instead of adding another set of options to 'old' cpp generator I've started 
> creating new one in:
> https://github.com/hcorg/thrift/tree/cpp11_generator
> using old as an reference
> main goals:
>  * code compatible with old librart (at least for first tests, new lib and 
> compiler switches can be added later)
>  * no more ugly {{__isset}} structure -> boost::optional for optional values
>  * as a result - no more {{__}} in names, which violates C++ standard
>  * all generation code will have own unit tests (TDD used wherever possible)
>  * generated types headers independent from Thrift header, to allow other 
> layers of application using generated types without dependency leaks
>  * each type will generate own header/cpp file - easier for user to include 
> only used parts.
>  * unordered map/sets
>  * returning using move semantics, no more ugly 'return via output parameter' 
> (still possible as option thou - sometimes it's needed for performance)
>  * async client using boost::future
>  * enum classes
>  * initializer lists for constants (maybe)
> I'm aiming in C++11 subset available in gcc 4.8 and MSVC 2013
> currently I have only complete enum generation, but work is in progress
> all comments etc are very welcome :)
