Rebol cgi always prints usage information before executing script ??

 [1/8] from: Jean:Holzammer:faedv-n:bayern at: 27-Jun-2003 12:45


Hello, as my web hoster doesn't support rebol officially, I tried to install it myself. Uploaded latest rebol/view binary (2.5.5.10) for Linux/X86 to my cgi-bin directory and set permission to 755. I also copied rebol.r and my script info.r to the same location. When I call this script from the web browser, it was actually executed. But rebol printed its usage information before it ! I tried to reproduce this at my local machine (AmigaOS 3.x/68K, Rebol 2.5.0.x) from the shell. I got the same behaviour, but only when I used an additional option that is not known, e.g. : rebol -cswq -dummyoption info.r But if you compare my script with the usage template as shown in the browser window, my script does _not_ use any unknown parameters !!! Any ideas ? Maybe the latest rebol version has different parameters but still old usage information ? Regards, Jean script info.r look like this: #! rebol -cswq REBOL [] print "Content-Type: text/html" print "" print "<pre>" probe system/options/cgi print "</pre>" output in the browser is: REBOL <options> <script> <arguments> All fields are optional. Supported options are: --cgi (-c) Check for CGI input --do expr Evaluate expression --link url Connect to Link --help (-?) Display this usage information --nowindow (-w) Do not open a window --noinstall (-i) Do not install (Link, View) --quiet (-q) Don't print banners --reinstall (+i) Force an install (Link, View) --script file Explicitly specify script --secure level Set security: allow ask throw quit --trace (-t) Enable trace mode --uninstall (-u) Uninstall REBOL (Link, View) Other command line options: +q Force not quiet (Link, View) -s No security +s Full security -- args Provide args without a script Examples: REBOL script.r REBOL -s script.r REBOL script.r 10:30 [test--domain--dom] REBOL script.r --do "verbose: true" REBOL -cswq REBOL --cgi --secure throw --script cgi.r "debug: true"12:38 27.06.03 Content-Type: text/html <pre> make object!

Usually this is because of line terminators. If you have edited the script on Windows and then uploaded to a Unix box in binary mode, the line terminators will remain CRLF, which is not a problem for REBOL but is for some Unix's shebang line handling.

Also, one can't usually use /View as Cgi on Linux due to the need to load up xwindows. Still waiting for Core/Pro... -- Graham Chiu http://www.compkarori.com/vanilla/

I haven't read all the threads on this but a while back I was aving all kinds of problems with "working" cgi, i.e., they were working. What it came down to was I was uploading them via FTP as binaries instead of ASCII. That was all it took to fix the problem. James On Sat, 28 Jun 2003 08:38:01 +1200 "Graham Chiu" wrote:

I've seen this problem too. I believe that it is caused if a CR character (13) is present at the end of first line (shell command) on Unix/Linux systems. REBOL scripts do not care about CRs, but the command line does. To fix the problem you can either use ASCII FTP to upload your script or on the server run REBOL and type: write %yourscript.r read %yourscript.r to remove the CR. It turns out that the latest versions of REBOL were supposed to detect this situation, so we are investigating why it is still a problem. -Carl

Hi, thanks. That was it. Never had the idea this could be the problem. I saved the script on an Amiga System, so there should not have been any CRs at all ? After explicitly removing these chars, it works now. Regards, Jean

Hmm, maybe there has been a (wrong) conversion during the transfer? What editor did you use?

I saved the file using GoldEd (v 6) directly to the server (via ftp: device). File Properties were set to CR/LF. Don't think this is the default.
