Perl: How do I "Require" or "Include" another perl script file?

[Jasoco]

Say I have this one Perl file (page.pl) and I have a separate Perl file (subs.pl) that I want to call Subroutines in.

I'd keep the Subs in the subs.pl file and from my other PL file I would call the subroutine. But how do I "Require" or "Include" the "subs.pl" file?

This is the only thing holding me from a total site redesign.

Hello!

I am just learning CGI so I do not know if this is right but I think all you have to do is put the following line of code into your file underneath your #!/usr/bin/perl line:

require "subs.pl";

Let me know if this works.

Have a great day!

Nope. Doesn't work.

CGI Error

The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:

Can't locate settings.pl in @INC (@INC contains: D:/activeperl/lib D:/activeperl/site/lib .) at D:\Inetpub\jasoco\cgi-bin\test.pl line 4.

Seems the test files I created aren't written right I guess?

test.pl

use CGI;
#!/usr/bin/perl

require "settings.pl";

print "Content-type: text/html\n\n";

&TestSub;

settings.pl

use CGI;
#!/usr/bin/perl

Sub TestSub {
print "Hello!";
}

Hello!

Is the file "settings.pl" in the same directory as your main CGI script? It will need to be. If this does not work try using the absolute path to "settings.pl"

Let me know what happens!

The Settings file is in the same directory as the Test file. The error page seems to imply the program is looking in its own directory for the files so I tired an absolute path (D:/Inetpub/jasoco/cgi-bin/settings.pl) Which seems to get passed THAT, but now I have a whole new error.

syntax error at D:/Inetpub/jasoco/cgi-bin/settings.pl line 6, near "}"

I seem to have it Requiring right, but now I have a problem with the Required files code.

Am I doing the Sub wrong? Or what? This whole Require part is the ONLY thing keeping me from advancing my site further and I've been racking my brain trying to figure it out!

[martinatkinson]

Hello!

Hmmm, looks like my code only works if the contents of your settings.pl file are defining variables, for example, this is a clip out of one of my scripts:

# path to template file
$template_file="template.html";


And then in your main file you could do something like:

require "config.pl";

#program start

$top_page=top_page($template_file);
$bottom_page=bottom_page($template_file);

Other then that I do not know, I am just starting to learn Perl so I guess I was not much help.

Have a great day!

Don't feel bad. You're the third person to try and help me with Requiring. I can't seem to find info anywhere. Noone seems to know how to do it the way I need it done. Hmmm


Well, I guess I'll look on Perl.com and CPAN again later.

If they don't help, can anyone recommend a Perl book?

I wonder if my server supports PHP...? Anyone have a way I can test? I don't own the server. The only way I know I can do Perl is that I put a file up and ran it. When it worked, I knew. But I need a sample PHP file I can upload and try. My host didn't tell me anything about what I can do and what I can't.

I've never had to work with CGI on NT, so don't know if this will help. Try using the http path to the script for the require, like:

require "http://www.domain.ca/cgi-bin/settings.pl";
