tty --- Terminal control functions

Code source : Lib/tty.py


Le module tty expose des fonctions permettant de mettre le tty en mode cbreak ou raw.

Availability: Unix.

Puisqu'il a besoin du module termios, il ne fonctionnera que sur Unix.

Le module tty définit les fonctions suivantes :

tty.cfmakeraw(mode)

Convert the tty attribute list mode, which is a list like the one returned by termios.tcgetattr(), to that of a tty in raw mode.

Added in version 3.12.

tty.cfmakecbreak(mode)

Convert the tty attribute list mode, which is a list like the one returned by termios.tcgetattr(), to that of a tty in cbreak mode.

This clears the ECHO and ICANON local mode flags in mode as well as setting the minimum input to 1 byte with no delay.

Added in version 3.12.

Modifié dans la version 3.12.2: The ICRNL flag is no longer cleared. This matches Linux and macOS stty cbreak behavior and what setcbreak() historically did.

tty.setraw(fd, when=termios.TCSAFLUSH)

Change the mode of the file descriptor fd to raw. If when is omitted, it defaults to termios.TCSAFLUSH, and is passed to termios.tcsetattr(). The return value of termios.tcgetattr() is saved before setting fd to raw mode; this value is returned.

Modifié dans la version 3.12: The return value is now the original tty attributes, instead of None.

tty.setcbreak(fd, when=termios.TCSAFLUSH)

Change the mode of file descriptor fd to cbreak. If when is omitted, it defaults to termios.TCSAFLUSH, and is passed to termios.tcsetattr(). The return value of termios.tcgetattr() is saved before setting fd to cbreak mode; this value is returned.

This clears the ECHO and ICANON local mode flags as well as setting the minimum input to 1 byte with no delay.

Modifié dans la version 3.12: The return value is now the original tty attributes, instead of None.

Modifié dans la version 3.12.2: The ICRNL flag is no longer cleared. This restores the behavior of Python 3.11 and earlier as well as matching what Linux, macOS, & BSDs describe in their stty(1) man pages regarding cbreak mode.
