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

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]
