Including code without packaging?

[MrCromeDome]

In my earlier post, I had created a function to read values from a configuration/INI file (and for those who contributed advice, thank you!). I want to use this function in multiple perl scripts. While I could just copy the code to each script, I don't want to have to change the code in every script when I make a change.

I realize I could make this into a package, but that seems like overkill for just one function. Is there anything in perl equivalent to #include in C other than making a module of it? Making a module looks a bit beyond me at this point.

Use "require" as opposed to "use". You don't need to have any packages or the like with require, though if you look at it's man page, there are a few gotchas for how you call it. But this will do what you are looking for.

I could be slightly annoying and point out Config::IniFiles already exists. Then again, "rolling your own" can frequently be fun.

As to your exact question, I would make a package anyway. It only adds a few lines to the file and I can almost promise you this code will grow. More functions will be added, maybe some different variables to control how errors are handled, etc. If you start with a package now, it will save you some hassle later.

Of course, ymmv

When I check cpan for this I can only access the README, the module gives a "Not Found". Is this a CPAN problem or has the module been removed?

I agree with your viewpoint..I personally have a module named MyUtilities where i just stuff algos i use over and over. One day a REAL module may just spontaneously jump out of it. Meanwhile i use it just like a junk drawer for code... :)

Making a simple module is not difficult and does not require you to learn O-O programming or anything other than a basic formula. For a module with just the function 'foo' create Foo.pm with the following:

package   Foo;
require   Exporter;
@ISA      =qw(Exporter);
@EXPORT   =qw(foo); # List funcs to export here
sub foo($){
   print @_;
}

To use it:

use Foo;
foo("Hello\n");

AppConfig takes care of this. From the docs:

       Configuration files may be arranged in blocks as per the
       style of Win32 "INI" files.

           [file]
           site = kfs
           src  = ~/websrc/docs/$site
           lib  = ~/websrc/lib
           dest = ~/public_html/$site

           [page]
           header = $lib/header
           footer = $lib/footer
