'launch and scripts running other scripts.

Alan I tried 'launch and it works for me. I wrote a launch-test.r script: REBOL [] view layout [ button "imagine" [launch %imagine.r] button "quit" [unview/all] ] My %imagine.r does a number of things, so is a good test I think: uses request-file to select a PNG file, then extract and execute an embedded rebol script, opening another window printing the output if the embedded script if needs be. The nice thing is I can keep on doing this as long as I liek becuase launch-test gui is just sitting their independently :-) Just what I think we both needed. That is how it behaves when I run it from within the _same_ directory it starts from: do %launch-test.r But when I move it somewhere else in the directory structure, for example: do %../tools/launch-test.r then I do have a obvious problem. REBOL/View looks for a REBOL installation in ../tools directory and if it does not find it, then throws up its installation GUI [the first time]. The next time it will run dierctly as it finds rebol.exe in ../tools. This behavior is something generally I still don't understand about REBOL/View [Win98se]. Namely why and when REBOL/View plants more versions of rebol.exe all over the file structure. I don't know if my config is damaged, or if there is a simple refinement or script param needed to avoid this. I hope this is some help to you, and that we both get sorted soon. cheers ./Jason ----- Original Message ----- From: "alan parman" <[reboler--programmer--net]> To: <[rebol-list--rebol--com]> Sent: Wednesday, December 19, 2001 10:07 AM Subject: [REBOL] 'launch and scripts running other scripts.

I tried the script you posted (with my own programs), but when I ran it, I got a REBOL Dialog box that says "Launch can only be used by launcher programs." The dialog box has an OK button. I don't get an error. I haven't read all of the posts on this subject. What did I miss? This would be a great way to collect all my programs into a menu.

RE: [REBOL] Re: 'launch and scripts running other scripts. if you start rebol to run a script, launch is disabled after %user.r finishs. you have to go to console and start script from there by hand. seems its more meant to be an internal function for desktop than a general tool. -Volker [hijim--pronet--net] wrote:

I actually think that it is a CGI special, but that is just what I think. ;-) It doesn't do with /view or /core so... Enjoy!! Ammon

Hi, The macintosh version of rebol/view also insists on creating FIVE copies of the executable the first time it runs. It is very irritating, and I cannot find any reason for doing that. If you try to delete them, they are automatically re-created at the next run. The unix version has another ennoyance. When it runs for the first time, it apparently wants to rewrite the executable file. It is OK if you have your own version of the program, but if you install rebol in a well known directory (/bin or /usr/bin for example) for a public usage, rebol stops and complains about the rebol file being not found or not writable. RT says that rebol is very easy to install, just copy and run, but I do not agree. There seems to be a lot of unnecessary complicated things going on in our back, and there is not explanation of them anywhere. It is a pity because rebol is really a great language which I try to promote in my company, but I need arguments to refute criticisms against this strange behaviour.

Holger, Thank you for the informations about the launch process. Now that I see the full picture, I think I will encapsulate the rebol command into a shell script , in order to check for the existence of the .rebol file in the current user's directory, and set the environment expected by rebol, whenever it doesnt exist yet. Cheers
