read_until for string_ref

[Olaf van der Spek <ml@…>]

string_ref read_until(string_ref& is, const char* sep);

Could we have a function like this that reads until a separator, returns the part before the separator and then eats the separator? It should read and return the entire input if no separator is found.

I have a problem with calling this "read", because string_view does providing a stream-like interface.

head might be a better name for what you are proposing.

And the general case here is (I believe) split (string_view, delimiter) which returns some kind of container of string_views.

Hrm...

Replying to marshall:

Does NOT.

Sheesh.

Would head still forward the begin pointer of the string_ref? IMO read is fine, Asio has a read_until too.
