package require Tcl 8.4
package require term::receive ?0.1?
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.
