Synopsis

use Terminal::MakeRaw;

# Save the current terminal attributes.
  my $saved_termios = Terminal::MakeRaw::getattr($*IN.native-descriptor);

# Change the terminal to raw mode.
  Terminal::MakeRaw::makeraw($*IN.native-descriptor, :FLUSH);

# And once we're done, reset the terminal to it's previous state.
  Terminal::MakeRaw.setattr($*IN.native-descriptor, $saved_termios, :FLUSH);

Description

Set and reset a terminal to raw mode using the termios native interface.

This module is a stripped down version of Term::termios. I contrast to the more feature rich Term::termios, this module does not require a compiler to be built.

Flags

Terminal::MakeRaw::makeraw and Terminal::MakeRaw.setattr can take one of the following flags that determine when the changes should take effect:

NOW

The default. The changes are applied immediately.

DRAIN

The changes are applied after all output written to the FD has been sent.

FLUSH

The changes are applied after all output written to the FD has been sent. All input that has been received but not read will be discarded.

See the manpage termios(3) for information about the flags and the termios API in general.
