[REBOL] launch behaviour and quitting
From: arolls:bigpond:au at: 4-Jun-2001 15:40
I disagree with the current launch behaviour,
where a launched program can't launch another.
This is to prevent launch loops, it is said.
But we can still have 'do loops.
A done program can still 'do another.
And that is useful.
It's useful to have loops.
Think of a web browser: a page has a link to
another page which links back to the first
one. That's a good thing.
I suggest allowing launching of programs
to a certain limit, say 10, after which
you could pop a window which says:
Script requests permission to launch
program x
Yes No YesToAll Quit
(or just an error message could be better).
Otherwise it is difficult to make your
own launcher which is itself launched.
ie. from my reb-site:
http://users.bigpond.net.au/datababies/anton/rebol/index.r
Click on the "start" icon to start my mini-launcher.
It does its best to launch other programs.
The problem is that those programs have the
capability to 'quit.
For example: click on the second icon under
Animations
, "anim.r".
You can quit this program in two ways:
- press "Quit" button (quits everything)
- press window close button (continues with calling
script, start.r)
I would like to know if there is a command I can use
in a script which allows me to quit as if I had pressed
the close button in the window.
ie. "continue from the bottom of this script"
If there isn't one I suggest a refinement of 'halt:
halt/only.
What do you reckon?
Anton.
