1. Euphoria and CGI
I have a CGI question. How do you make a page automatically refresh?
Like...there are several things that I want to do like this. And, this
example is not one of them..but would be an easy example of what I'm looking
for...
Example:
What if you put a clock at the top of your page and you wanted the clock to
automatically refresh every minute, so that you didn't have to click a
"reload" button to make the clock stay on the right minute. How would you
do this? (I'm using Euphoria/Windows with Apache on my own computer, if any
of that makes any difference)

The only way to implement this feature is in the Header tags
Example:
<html>
<head>
<meta http-equiv="Refresh" content="1; URL=http://128.0.0.1/this_page.exw">
</head>
<body>
<center><a href="http://128.0.0.1/this_page.exw">Refresh</a></center>
</body>
</html>
The first part of the content, seperated by a semi-colon, is the timeout
waiting period. 1 means it'll wait 1 second, 0 means it'll
automatically refresh. If you want to use re-direct, the easy way to do
that is:
puts(1,"Location: http://128.0.0.1/this_page.exw\n\n")
That's what you would output automatically, before _ANY_ headers are sent.
Headers consist of:
puts(1,"Content-type: text/html\n\n")
puts(1,"Content-type: text/plain\n\n")
puts(1,"Content-type: image/gif\n\n")
puts(1,"Content-type: image/jpeg\n\n")
etc
etc
Hope this helps.
3. Re: Euphoria and CGI
Right, What he said. However I wouldn't use that method for any page that
was larger than the screen. The reload/refresh will cause the page to reset
to the top.
You've read 2 screens worth of a 5 screen webpage and it decides to reload
on you because of the timer. Very annoying.
It is good for 10 second delay between reloads of a 10 second updated image.
Slow webcam. 20 second, 30 second. Whatever.
Also good for webpage designing. Set it to reload to the current page at
an anchor spot. file:///C:/page.htm#edit_area
<a name="edit_area"></a>
Then when it reloads it will always jump down to where you are editing.
But I usually find it faster & easier to ALT-Tab to reach the browser, then
press F5 for refresh. I usually am just flipping back and forth between my
editor and the browser. A single Alt-Tab from each keeps flipping me
back and forth.

See this:

Basically, it's a META tag inside the <HEAD>:

Not until somebody creates a browser plug-in for Euphoria,
like you have for Flash or java (in which those games are programmed).
That should be easy, though. Bug one of the gurus for it. Or even
Rob Craig himself! Rob?!?!?!

Well, you'll notice I said bug a *guru*! That would have to
be someone else. (I'm thinking Matt Lewis might be a good start...)

11. Euphoria and CGI
Why doesn't this work?
#!./exu
puts(1, "<html><head><title>Quackery Game</title></head>\n")
puts(1, "<body bgcolor=\"#FFFFFF\">\n")
puts(1, "</body></html>\n")
I tried with /euphoria in /public_html and in the top level.
In /public_html I get:
#!./exu puts(1, "\n") puts(1, "\n") puts(1, "\n")
In the top level it does nothing.
/euphoria consists of /bin and /include
Also
#!/home/jstory/euphoria/bin/exu
doesn't work on my computer even tho the path is correct.

- be careful that your #! line has just \n as the line terminator,
*not* \r\n (DOS/WIN style)
- be sure that exu has execute permission by all users

I don't see you outputting a content type,
eg puts(1, "Content-type: text/html\n\n")
(unless that was assumed in your example)

I forgot that.
Here is a modified version:
#!/public_html/cgi-bin/euphoria/bin/exwc.exe
without warning
puts(1, "Content-type: text/html\n\n")
puts(1, "<html><head><title>Quackery Game</title></head>\n")
puts(1, "<body bgcolor=\"#FFFFFF\">\n")
puts(1, "</body></html>\n")
This is what it does.
#!/public_html/cgi-bin/euphoria/bin/exwc.exe without warning puts(1,
"Content-type: text/html\n\n") puts(1, "\n") puts(1, "\n") puts(1, "\n")
On a blue screen.

It seems the web server you're using is not executing that file but just giving
it's contents. Be sure your server is setup to execute it.

The #! line has the correct path.
exu works on everything else.

Have you modified your htaccess files? Sounds like Apache (or whatever web
server you're using) doesn't know what to do with Euphoria source files.

What, who is htaccess?
I'm using Opera. Opera understands html files.
Firefox does the same thing, with a different shade of blue.

You should have a read of this link (on the Wiki): <A
HREF="http://euwiki.ayo.biz/Can_Euphoria_do_CGI%3F">http://euwiki.ayo.biz/Can_Euphoria_do_CGI%3F</A>
Halfway down it explains how to set up your web server to execute the CGI
script.

I'm trying to run the following code on my computer.
(If I can't get it happening on my computer, then I probably
can't get it happening on my ISP's computer.)
#!/home/jstory/euphoria/bin/exu

puts(1, "<html><head><title>Quackery Game</title></head>\n")

What next?
I'm too stupid to understand the euwiki article about CGI_Apache.

What is Apache? (I looked this up on Google but I don't understand anything.)
How can I know whether I have Apache installed?
What does Apache have to do with running a html file on firefox or opera?

Apache is the program on your computer that serves web pages.

You will have installed it. Go download it and install it to your computer,
then read up on it. Time for an education if you want to go further.
> What does Apache have to do with running a html file on firefox or opera?
You can view an HTML file without Apache, but you need Apache when
you want dynamic serving of web pages. That is, they are not "static" HTML
text files, but actually programs that need an interpreter.
For instance, http://www.cklester.com/euphoria/bbcmf/ is being generated with
a FreeBSD Euphoria interpreter and served by Apache on FreeBSD 4.x.
