Re: [Bug-apl] Request to implement ^S and ^Q

[Elias Mårtenson]

Being someone who used this feature extensively back when I was using serial terminals, I've never had any use of that feature on modern computers. They're just too fast, and you'll have scrolled hundreds of pages before you even have time to reach for C-s. 

I'm curious as to what use you have for this?

Request to implement ^S and ^Q in the interactive session.

In a Linux terminal, when something is scrolling too fast you can always press Control-S (meaning stop) to freeze the display
so you can see what happening, and scroll up/down, then you press Control-Q (meaning continue) and it will resume.

Those 2 signals are actually ignored by the actual interactive apl interface. (to be proven, not sure at 100%)

My guest is that if they were not ignored, the default will actually do the job (suspend and resume) without any programming changes.


I may be wrong.

Xtian.

you can test it on Linux by issuing "cat `a *very large file*`" and typing Control-S (to stop) .... then Control-D (to resume) displaying.
