NAME
Term::Completion::_POSIX - utility package for Term::Completion using POSIX termios
DESCRIPTION
This utility package contains few methods that are required for Term::Completion to put the terminal in "raw" mode and back. This package uses POSIX termios to accomplish this, which should be portable across many UNIX-like systems. It was successfully tested on Solaris and Linux.
Methods
- set_raw_tty()
-
Uses "POSIX::Termios" in POSIX and related methods to set the terminal into "raw" mode, i.e. switch off the meaning of any control characters like CRTL-C etc. Also the echo of characters is switched off, so that the program has full control of what is typed and displayed.
Uses the "in" field of the Term::Completion object to get the input file handle. Won't do anything if this is not a TTY. See also "-X" in perlfunc.
- reset_tty()
-
Resets the terminal to its previous state, which was saved in the object's fields (
_tty_XXX). - get_key()
-
Reads one byte from the input handle. Internally uses "getc" in perlfunc.
