Re: How to detect terminal type?

[Peter Brinkmann]

Joshua, Miquel,
Thanks for your prompt reply! Unfortunately, neither gshow nor gget will
work for my purposes.

My current situation is this: I'm developing educational software under
Linux, but it also has to work under Windows because that's what most of
my students are using. I was hoping to be able to write some code that
automatically detects, remembers, and resets the terminal type, like

        terminal_type=get_terminal_type();      % remember terminal type
        gset terminal postscript
        ... create postscript output
        gset(['terminal ' terminal_type]);      % reset terminal type

Now it appears that this won't work because gshow only displays its result
but doesn't return a value, and gget only works under *nix, in which
case I already know the result.

I'm afraid I'll have to do something like

        gset terminal postscript
        ... create postscript output
        if running_under_unix
                gset('terminal x11')
        else
                gset('terminal windows')
        end

This is ugly, but I don't see a better solution.

So, my new question is, what's the best way to detect whether my code is
running under *nix or Windows? I guess I could look at the result of
computer(), but I don't know what kind of result it returns when running
under Windows. Can I detect Windows by checking whether
        findstr(computer(),'windows')
returns a nonzero value, or how should I go about this?
Thanks,
        Peter
