NAME

       term::receive - General input from terminals

SYNOPSIS

       package require Tcl  8.4

       package require term::receive  ?0.1?

       ::term::receive::getch ?chan?

       ::term::receive::listen cmd ?chan?

       cmd process string

       cmd eof

       ::term::receive::unlisten ?chan?

_________________________________________________________________

DESCRIPTION

       This  package  provides	the most primitive commands for receiving characters to a terminal. They are in essence convenient wrappers around
       the builtin commands read and fileevent.

       ::term::receive::getch ?chan?
	      This command reads a single character from the channel with handle chan and returns it as the result of the command.

	      If not specified chan defaults to stdin.

	      It is the responsibility of the caller to make sure that the channel can provide single characters. On unix this can  be	done,  for
	      example, by using the command of package term::ansi::ctrl::unix.

       ::term::receive::listen cmd ?chan?
	      This  command  sets  up  a filevent listener for the channel with handle chan and invokes the command prefix cmd whenever characters
	      have been received, or EOF was reached.

	      If not specified chan defaults to stdin.

	      The signature of the command prefix is

	      cmd process string
		     This method is invoked when characters were received, and string holds them for processing.

	      cmd eof
		     This method is invoked when EOF was reached on the channel we listen on.  It will be the last call  to  be  received  by  the
		     callback.

       ::term::receive::unlisten ?chan?
	      This command disables the filevent listener for the channel with handle chan.

	      If not specified chan defaults to stdin.
