NAME¶
term::receive - General input from terminalsSYNOPSIS¶
package require Tcl 8.4DESCRIPTION¶
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.
- ::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.
- 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.
