Users should be able to create observable adapters over the standard library collections.

The wrappers should be inspired by std::queue and the rest of the container adapters in the standard library.

Adapters for new or custom containers should be easy to create.

So, is it not yet implemented? Everything looked so cool for a single variable, but without arrays, the library is of no use :(

Actually, I managed to compose quick & dirty solution on my own: https://bitbucket.org/kornerr/c-observable-variables/src/tip

Though, it handles std::vector type by redefining its push_back method, which is not all cool, but works as a drop-in replacement.

Hi @kornerr,

Yeah, having observable collections would be pretty cool, but I haven't found the time to implement them yet. You're welcome to try adding support for this.

Fix ddinu#8: Add observable collection
36c573c 
Add wrapper around std::unordered_set to implement insertion and removal
of items from a collection. The collection inherits from a value, and
can be subscribed to as usual to yield notifications on assignment. The
collection also provides subscribe_changes which notifies observers on
successful insertion into and deletion from the collection
