cli_widgets : text based widgets

This library is thought to add easily in C++ application some common command line widgets.

For the moment the following is supported :

cli_widgets::spin_loader

cli_widgets::spin_loader loader(std::cout);
loader.launch();
  some_long_running_computation();
loader.stop();

See spin_loader.cpp for more example.

cli_widgets::hidden_input_guard

std::string passphrase;
std::cout << "Please enter your password : ";

{
  cli_widgets::hidden_input_guard hide_password{};
  std::cin >> passphrase;
}

See stdin_hide_guard.cpp for more example.

cli_widgets::symbol_cycler

The no-need-to-worry-about-collection-boundaries-circular-iterrator-string-symbol-spinner:

const std::vector<std::string> symbols { "v", "<", "^", ">" };
cli_widgets::symbol_cycler spinner(symbols);

for(int i = 50; i > 0; i--) {
  std::cout << "\r" << spinner.next() << std::flush;
  std::this_thread::sleep_for(step_slow);
}

There are a bunch of symbol collections to be found in the cli_widgets::spinner_symbols namespace!

A fully fledged example, including of how to use this one in conjunction with cli_widgets::symbol_cycler can be found in symbol_cycler.cpp.
