I noticed fmt::output_file() returns a special fmt::ostream. It'd be nice if there was something similar for printing to the screen (cout stream replacement) / building into a string (ostringstream replacement).
Then we could do something like this:
void build_text(fmt::ostream& stream)
{
stream.print("Hello {}\n", "world");
stream.print('foobar");
}
// Doesn't matter how you call it!
void to_console()
{
auto stream = fmt::print(); // no argument overload? or alternative console_stream();
build_text(stream);
}
void to_file()
{
auto stream = fmt::output_file("myfile");
build_text(stream);
}
void to_string()
{
auto stream = fmt::string_stream();
build_text(stream);
// to text!
const std::string text = fmt::to_string(stream);
}
at the moment I think we have to fall back to stl streams in order to do this? But I thought those were slow in practice.
Please let me know if there's something I'm missing!
