I went to
http://www.rapideuphoria.com/cgi.htm
This is the documentation that explains how to do CGI with Euphoria.
From the above I downloaded the source of
http://www.rapideuphoria.com/ecoform.htm
and
http://www.rapideuphoria.com/economy.txt
Then I renamed "economy.txt" to "economy.exu"
so it fits with
<form method="POST" action="cgi-bin/economy.exu">
And I changed "rds at RapidEuphoria.com" to my email address.
constant emailaddress = "rds at RapidEuphoria.com",
Then I ran ecoform.htm with Opera on my computer.
I filled out the form and clicked on submit.
Got an error message. Could not open the file.
Then I changed
<form method="POST" action="cgi-bin/economy.exu">
to
<form method="POST" action="economy.exu">
This is in the local directory.
Clicked on the refresh button, filled out the form again, clicked on submit.
Gotta blue screen with a bunch of source code on it.
And no email message.
How can I get CGI happening with Euphoria?

What do you mean by 'ran' in the first sentence above? Do you mean that you
opened the page in a browser? Or do you mean that you served it to a browser with
a web server?
The latter is what's required ... IIS would work if it's on a Windows machine,
else Apache is the norm. There are others.
If none of this makes any sense, I (and no doubt others) would be happy to
explain further.

I opened the page in a browser.
But just a few minutes ago I put ecoform.htm and economy.exu on my website and
then I opened ecoform.htm in a browser. At first it said POST is not allowed. So
I changed POST to GET. Now it displays economy.exu. Still don't have it right.
economy.exu seems to have code in it that handles GET.
My ISP is Telus.

Jerry, you have to have a web server running that receives the incoming
HTTP request and is able to serve up the page. So, for example, Apache would
run your exu program and send the output to the browser.
Without the web server, nothing gets served to the browser (or it acts like
a file viewer).

The web server also has to have some way of knowing how to invoke the
interpreter.
the economy program assumes a Linux based server (#!.exu is the interpreter
invoked)
IIS I believe you have to some
alternatey, if you have cleared the syntax,
you can bind a program into a CGI executable

What is a web server? I use Telus. Is Telus a web server?
This is Telus.

That won't work.
I suspect that you have not properly read http://www.rapideuphoria.com/cgi.htm.
Please do so before proceeding.
You might also read this page of mine: http://www.wazu.jp/hosting/CGI.html

There's a bit more than that to it.

Sorry, are we meant to know who that is?
Does your ISP allow you to install Euphoria? To modify .htaccess so that
Euphoria will be recognised as a program to execute CGI?

A few minutes ago I installed Apache. Now what do I gotta do with Apache?

http://en.wikipedia.org/wiki/.htaccess. Not sure why I'm doing your homework for
you. You say you've just installed Apache, but you haven't (for some reason) read
its documentation?
Oops. Smacks own wrist.

There is some documentation on the internet about this. I would recommend
searching the mailing list archive for "CGI" problems.
I had the same problem as you, I tried off and on for ages to get euphoria
working through CGI. I changed everything around so much I recognize in
retrospect I got 99% of this right everytime but also I missed one directive
everytime too. Please realise before you get frustrated with euphoria that it is
*worth* investing time learning the concept of CGI programming in general - it
will help with whatever language you end up using to do CGI.
To do any CGI you have to have a webserver, basically. It's easiest if you use
Apache for this because it's the dominant server and there is more documentation
for this than any other at present (due to its cultural lineage).authoritave
I'm making a presumption you are using Windows here. Install Apache as normal,
using the default options. This should add "Apache" to your "Start Menu"
programs. Under "Apache HTTP Server ......" You will find "Configure Apache
Server", on which click "Edit Apache httpd.conf...."
This is a file you're going to have to get used to. Apache is generally
configured by a text configuration file, rather than tabbed dialog windows like
most programs. It's easier if you just bite the bullet and experiment. I would
save the original file as a backup somewhere, and go nuts with the following (you
can always revert to the saved version - don't delete it!)
First, read the website http://www.cklester.com/euphoria/?page=apache - this is
the most authorative website I have seen on this issue. Don't worry if parts of
it go over your head, just do it all step by step, and experiment ( I cannot
stress enough - back-up the original httpd.conf ).
These are the first things I do when setting up Euphoria for CGI on a new
computer
*) First things first, you need apache to be working - hit your ip address in
your web browser, and it should give you a page that informs you Apache is
working. If it is not working, there's no point even contemplating CGI - you'll
need a webserver. If it doesn't work "out of the box" then you'll need to take
this to an Apache specific group. Apache must work first and foremost
*) Create a shorcut to Apache Error log file on your desktop or whatever folder
is easiest for you. Go to the Start Menu, to Apache, then Review Server Log
Files, then "Review Error Log". Left click on it, move it over your desktop or
whereever is a convenient folder to have the link, and hold down the ALT key
before you let go (this creates a shortcut, rather than moving the menu item).
You'll need it.
*) Through the start menu (you might want to create a shortcut for this too),
edit httpd.conf for the following lines: the easiest way is to copy these and
"search" for them in the text file
Find the line "LoadModule cgi_module modules/mod_cgi.so" - make sure it does not
have the character '#' at the start of the line. It should look like this
LoadModule cgi_module modules/mod_cgi.so
not this
#LoadModule cgi_module modules/mod_cgi.so
Go through the steps as detailed on CK Lesters website
A good way to test whether Euphoria is working or not as a CGI implementation is
to create a file in your web directory which is "Euphoric" (following what the CK
Lester website documents, ends in exw,exu, etcetera)
Hit it. If it says "Internal Server Error" then you are away laughinng. Euphoria
is working with CGI, you just need to move onto the next step which is simple -
the first line of every "euphoria cgi file" should be a "shebang" line - a #
followed by the path to the Euphoria interpreter. for now just put the full
windows path
Secondly, the second line of each file should be this :
puts(1,"content-type:text/html\n\n")
Then put something like this or whatever:
puts(1,"Hello World!")
It can get a lot more complicated than this, but you'd be moving onto the world
of the world wide web, rather than specific Euphoria example problems.
I'm sorry it sounds so complicated, but you'd have to cover half of this to
really even get anywhere with PHP, which is *substantially* more complex and
slower than Euphoria.
On a final note, with Apache every directory is allowed to be defined privelages
- in Linux you can define some of these through the Operating System itself - but
you can also define these in a file also. You can control a whole lot of shit
through the .htaccess file, but you should not need to deal with it certainly not
before you've mastered simple euphoria programs.

I'm no expert on CGI but I think I see the problem here. Others have tried to
explain it but let me take a shot.
First, let me ask "what do you want to do"? Are you trying to serve web pages to
the world from your ISP (Telus) or are you trying to serve web pages from your
own personal computer?
Usually when you view an HTML file on your personal computer, the web browser is
just acting as a file viewer (and maybe a Javascript interpreter as well). By
itself, your web browser cannot execute CGI programs.
As others have pointed out, you really cannot make Apache work on your own
personal computer without reading some of the docs. It's not that hard, though.
When you get it running, instead of pointing your browser to
"http://c:/somefile.html" you want to point it to
"http://127.0.0.1/somefile.html". That's just a basic example, there is a little
more to it than that. But that should work if your webserver is running correctly
and "somefile.html" is in the location that the webserver expects it to be.
As for serving pages up to the world at large via your ISP, you will have to
contact their support people and tell them what you want to do and find out
whether it is possible or allowed.
Hope that helps!

Jerry, I've made a few modifications to my web site instructions on using
Apache and Euphoria. See if it makes a little more sense. For others, let
me know if there is something you think I should add or change to make it
more clear.

If you want a VERY easy way to set up Apache etc, nothing is easier than xampp:
http://www.apachefriends.org/en/index.html
Just download and extract. It's not really intended for "production" use, and by
default there are a few security holes, but these are easily fixed.

Thanks. I followed the instructions and reached where it said "It works!"
Thanks to everyone for their efforts to explain how to get CGI happening. I
tried to study the material. All of it is way over my head. CGI programming is
too techy for me, so I won't do that.
I had no idea it was so difficult. I expected my ISP (Telus) to have Apache and
all that stuff installed and ready to go.

Telus uses Apache as web server:

Keep trying and you'll succeed!

Good news! :) So, Apache is now successfully installed.
If you follow the directions at my site for modifying the Apache
configuration file, you'll be running a Euphoria-based website in no time!

If Telus is your ISP, then they are probably not your web host.
If they ARE your web host, then they probably have Apache installed.
You just have to reconfigure it to use it the way you want. Of course,
Telus might not allow CGI from its server, in which case you will need
to change hosts.
