Hello,

Has somebody news of the scope exit review result? The boost schedule page states it as Pending, and the review has been finish 6 months ago?

Regards

Scope Exit Alexander Nasonov Jody Hagins August 13, 2007 - August 22, 2007- Pending

There was some discussion of a more generic BOOST_LOCAL_FUNCTION. If used with ScopeGuard, you can emulate ScopeExit functionality, for example: // making names a bit shorter: LFN stands for BOOST_LOCAL_FUNCTION int main() { vector<int> v; vector<int>::size_type initial_size = v.size(); // Declare a nullary functor resize_v_fn void LFN( LFN_BIND( (ref v)(val initial_size) ) ) { v.resize(initial_size); } LFN_DECL( resize_v_fn ) ScopeGuard resize_v_guard = make_guard(resize_v_fn); // ... push_back one or more elements to v } or int main() { vector<int> v; // Declare an unary functor resize_v_fn with only v bound, // initial_size will be bound later by make_guard: void LFN( LFN_BIND( (ref v) ), vector<int>::size_type initial_size ) ) { v.resize(initial_size); } LFN_DECL( resize_v_fn ) ScopeGuard resize_v_guard = make_guard(resize_v_fn, v.size()); // ... push_back one or more elements to v } This could be even make shorter with LFN_ON_EXIT, except that expanded name BOOST_LOCAL_FUNCTION_ON_EXIT is very long: int main() { vector<int> v; vector<int>::size_type initial_size = v.size(); // Declare a nullary functor and convert it into a guard: void LFN( LFN_BIND( (ref v)(val initial_size) ) ) { v.resize(initial_size); } LFN_ON_EXIT // ... push_back one or more elements to v } So, I'm fine if Jody rejects the ScopeExit library but I can't say when I can submit LFN for review. I have a working version that don't yet support explicit binding by reference ( (ref v) in the code above) and by value ( (val initial_size) ) but I don't have time for further development. -- Alexander
