[REBOL] Re: [The Gimp] clashes with REBOL on Windows 2000
Hi Brian, thanks for your impressive answer! At the moment I can live again with my REBOL installation (as I wrote earlier) but surely I will save your e-mail in order to be able to use it when any such problem comes up again. Luckily enough I use an account with administrator rights and I don't use REBOL from any other accounts currently. That makes the case a lot less complicated for me then. Your suggestion to create a full-proof install-script sounds like a great idea. Perhaps it would be even better to also have the script clean-up any old REBOL installs before it does a new install? (In fact RT should also improve the install part or, perhaps even better, remove installation as it is done now.) All in all a very good idea Brian! I think it could help a lot of people. Thanks again.

You've run into a problem that tripped me up for a while: REBOL doesn't put its data in the proper places on Windows 2000 and above - in other words, it is not logo-compliant. REBOL's default install puts its program file and data files in a directory under Program Files. Since Windows security settings prevent a standard user from writing to these program directories, only a Power User or administrator has sufficient permissions to use REBOL/View by default. Fortunately you can hack a REBOL/View install manually to make it mostly logo-compliant, and thus allow it to be used by ordinary users without being a security risk. Here's a quick overview, assuming a standard install of Windows 2000 or above and REBOL/View 1.2.1 to 1.2.8 (please bear with me if you know some of this, I'm trying to make it useful to others that have the same problem): First, let REBOL/View install itself into some central place such as C:\Program Files\REBOL\View. This will set up most of the global settings in the registry and some of the local ones. Close REBOL. REBOL may have downloaded some files to this directory for the desktop - if this is a new install, you can delete everything but the program files. Next you need to create the local user settings. These are stored in the user profile directory, sort of like a user's home directory on Unix. Windows 2000 and above store their profiles in directories under C:\Documents and Settings, earlier versions of NT under C:\WINNT\Profiles. If you have trouble finding your profile an environment variable named USERPROFILE points to it automatically - this is like the Unix variable HOME, which is not defined by default on Windows. The Gimp uses USERPROFILE on Windows by default. Now, you'll need to repeat this for each user that already has a user profile created. Find the Application Data folder in the profile directory. It will be hidden. If you aren't sure where it is, there is an environment variable APPDATA that points to it. Create a REBOL subdirectory in that folder. That will be your REBOL home folder - make a note of where it is, it's time to hack the registry. Open a registry editor and find the key: HKEY_CURRENT_USER\Software\REBOL\View Under that key there will be a string value named HOME, which will contain a REBOL-format directory name without the % - change that value to match the REBOL home folder you created earlier, for example: /C/Documents and Settings/Ari/Application Data/REBOL/ You should be set now. When you start REBOL now it will start the program in C:\Program Files\REBOL\View and use your REBOL home as its working directory. If you moved over your data to that folder it should work right away; otherwise REBOL will download the files it needs. Now here comes the tricky part. You may have noticed that in under that same registry key there is another string value named Product. That key is the marker that REBOL uses to determine whether it is installed and current. The problem is that this key is in absolutely the wrong place - it should be under HKEY_LOCAL_MACHINE, as it is a global setting, and treated as such by REBOL. It is a global setting because REBOL associates .r files with the REBOL executable, something that can only be done globally, and also registers an uninstaller with the Add/Remove Programs control panel (which can be done in a per-user way but they don't). Since this setting is under HKEY_CURRENT_USER every user that runs REBOL for the first time triggers a reinstall, which then messes up the registry settings for everyone. This key can't be moved to the right place either, because REBOL looks for it where it is. This is a long-standing REBOL bug. All this means that you need to create REBOL directories and REBOL\View registry keys for every user on the system and for the

[REBOL] Re: cgi question
From: Kai Peters KP You see me confused, for the script works well with 'my' formatting (am KP coming from C and Pascal and have always wanted my braces and begin/end KP pairs lined up nicely). I thought I read somewhere that REBOL is very KP lenient when it comes to white space etc. including CR/LF etc.? From: Gregg Irwin GI Don't be confused, REBOL doesn't care at all about the formatting. ... With all due respect, I am not a formatting elitist, either, and was not meaning to sound critical of Kai's formatting. In retrospect, the point I failed to make is that when cutting and pasting into a REBOL command line session, one can run into formatting issues. Here is an example from Kai's program, when a snippet is cut and pasted into a REBOL session (at least on Windows): header: make system/standard/email ** Script Error: Invalid argument: (missing value) ** Near: header: make system/standard/email [ [To: [ recipient1 ] [From: [ [EMAIL PROTECTED] ] [Subject: subject [Organization: organization [] == [ To: [recipient1] From: [EMAIL PROTECTED] Subject: subject Organization: organization ] The same snippet runs without error when in a listing that is then run as a program. I frequently develop scripts by cutting and pasting from a text file into the command line. I can get large code fragments loaded, so that I can then play with the results interactively. With this method, at least on windows, REBOL *does* care about formatting. As a result I tend to make sure that block arguments at least have the opening bracket start on the same line. This is why I have so frequently warned of watch for line wrap when responding to email on the list: cutting and pasting the fragment may not work if the line received an unfortunate wrap location. I *just* realized that I sort of assumed everyone developed using these methods, and in that point I was being unfortunately narrow sighted. I apologize! With respect, best wishes to all!

I think it's best to just treat them as you would a number.
