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.
