santhosh_89 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks

I have downloaded a cpan module called Config::Abstract::Ini,It is available in my home directory and /usr/lib also.Default the @INC will have the /usr/lib path.But I want to take and use my home directory module.The path will be given from global values.If the values is empty,it should take default path(/usr/lib).If the home directory path is error,it should say an error.

if($path ne ''){ unshift(@INC,"$path"); } use Config::Abstract::Ini;

NOTE: I used above code it is searching from default directory.even I would give wrong path in global value.

Replies are listed 'Best First'.

    use is compiled before other normal code. You have either to use require or edit the include path in a BEGIN block before the use:

    use strict; use warnings; BEGIN { if ($path ne ''){ unshift @INC, $path; } } use Config::Abstract::Ini;

    Note that $path must be set (probably in a previous BEGIN block) before being used as shown above.

    True laziness is hard work
