Can a script run another script?

[1/8] from: reboler::programmer::net at: 14-Dec-2001 23:31

Can I run a script from a REBOL/View face? So far I can launch the new script, but the old face/script closes. I would like to pick a new script from a directory listing and run it, while keeping the old one open. Can REBOL/View do this? Or do I need View/Pro or Command?

HTH! --Gregg

Hi Alan I should add that the /New refinement, used with View (i.e. View/New) is another thing you may want to look at from the sounds of things. --Gregg

You can embed the script inside your %user.r setup file as a global variable with a line like this script_name: [ script ] And then simply call the script as a function/variable like this script_name this is the way it is designed to work, if you need an example -I can offer some.

Thanks Gregg, for pointing out the 'launch command. I hadn't noticed it before. It works great in simples scripts like ... view layout [button [launch %feedback.r]] But I have a larger script whose relevant contents boils down to this ... output: make object! [ file: %feedback.r ] view layout [ button "Do Script!" [ if script? output/file [ launch output/file ] ] ] The above works as a script unto itself, but within the larger script, I get the following error message... Launch can only be used by launcher programs in a REBOL/View Dialog Box. Since 'launch is undocumented, do you know what this error means?

'Launch is designed to launch programs only from the first script. It's a security measure. It's best to restructure your script. Andrew Martin ICQ: 26227169 http://valley.150m.com/

Is "the first script" the first one run by the REBOL? Does that include, for instance, the /View desktop? Chris Dicely

It doesn't include the ones in Rebol. Just your scripts.

It shouldn't include the desktop in View. Andrew Martin ICQ: 26227169 http://valley.150m.com/
