Thanks for the link to Boost.Text! I think I missed it in the discussion I read.
You're welcome.
Yes, indeed I think we all share similar ideas. Other than difference in design, I think the concept is quite similar to Chad's Unicode string library, though I don't know whether you two have seen each other's code.
I've reviewed Chad's library and his ideas of a Unicode string class gave inspiration for my Unicode string class, although with different design and intermediate goals.
Basically, my concept is also something like adding one more template parameter to your basic_text class to generalize string_type. Other than that, you have pretty much demonstrated my motivation to build such a class.
Thank you. I'm happy if my class can give anyone an ounce of inspiration or motivation.
One simple question to ask: May I know why is your class holding shared_ptr<basic_string<>> as the private member instead of simply basic_string<>? If I'm not wrong, basic_string<> is already a smart pointer to the underlying buffer and most implementation offers handy COW semantics. Or is there a need to wrap basic_string<> in shared_ptr<> because not all basic_string<> implementation is efficient?
I did so to ensure that the data was shared between instances, as some implementations does not use COW semantics. The basic_text class was initially designed to be immutable, but I don't know if that is always good. Now I think it would be better if instances could be appended at the end, that way one could use Mathias Gaunard's Unicode library without any intermediates.
Thanks.
