Disabling the terminal command echo¶
Sometimes it may be desirable to turn off the echo function in accept when entering commands. One solution to do it is to temporarily redirect the emit to do nothing.
variable tmpemit : -emit ['] emit defer@ tmpemit ! ['] drop is emit ; : +emit tmpemit @ is emit ;
> 1 2 3 ok > .s 0 809 3 1 80B 2 2 80D 1 ok > -emit .s +emit ok >
Alternately the definition
: +emit tmpemit @ ['] emit defer! ;
could be used as well.
