Storing Functions

dcoleyoung has asked for the wisdom of the Perl Monks concerning the following question:

Hello, Now I picture you guys as the dudes in the Nepalese mountains after seeing "Batman Begins".

I want to store functions that I'm writing in a common file so different files can use them. My approach right now is to store them in a file with "1;" at the end so it can be interpreted. In the calling files I have the line: require './perl_func';

Is there a better way of doing what I'm trying to do (storing functions in a common place)?

Thanks, Dan

See use. You may also like to examine Exporter and package. They say that time changes things, but you actually have to change them yourself. —Andy Warhol	[reply] [d/l]

You're on the right track already. Read Simple Module Tutorial for more. -xdg Code written by xdg and posted on PerlMonks is public domain. It is provided as is with no warranties, express or implied, of any kind. Posted code may not have been tested. Use of posted code is at your own risk.	[reply]

That is the way of "storing" (I'd say "organising" or "grouping" functions). What you have created is a Perl Module (often the files have a .pm extension). Take a look at Simple Module Tutorial for a little more information. DWIM is Perl's answer to Gödel	[reply]

For just loading your own functions, you can also use `do 'perl_func';`. There are some differences from `require`, although they aren't significant for what you seem to want. You might try `perldoc -f require` and `perldoc -f do` to compare.	[reply] [d/l] [select]
