How do I include a file and execute the code in the file?

on May 16, 2001 at 20:12 UTC ( #80940=perlquestion: print w/replies, xml ) Need Help??

xorl has asked for the wisdom of the Perl Monks concerning the following question: (files)

This is basically my script ....
if ($var eq "foo") { Include file1.pl and execute code } if ($var eq "bar") { Include file2.pl and execute code } else { Include file1.pl and execute code }
I tried using require but if I need to include the same file twice it tells me the libary is already loaded. Idealy I'd like something like PHP's include command.Any suggestions?
Thanks!
Xorl

    Have you looked at do?

    Use this sub:
    # Useage example: my $error = run_code('/file1.pl'); print "Run code failed, err msg:\n$error" if $error; sub run_code { my $path = shift; open(CODE, $path) || return "Oops: $path $!\n"; local $/; my $code = <CODE>; eval $code; return $@; }
    Needs full path to code to be run.

    The local $/ gives a locally undefined value to the input record seperator $/ with the result that we glob the whole file into $code. This saves us from @code = <CODE>; $code= join'',@code;

    The sub returns undef if it suceeds or the error message if it fails to run the code.

    Hope this helps.

    Write a module that exports functions. Call the functions instead of requireing the file. See perlmod or use Super Search to look for 'writing a module'.

    or why not simply use it like this? do 'something.pl'

    Umm... why would you need to include the file twice? If you don't like require complaining, you can store the files you've already included in a hash, then include files only if they are not already in the hash...
