if::prog - use a Perl module if program matches
use
This document describes version 0.01 of if::prog (from Perl distribution if-Pragmas), released on 2014-10-09.
In Perl script:
use if::prog 'foo|bar', MODULE => ARGUMENTS;
On command-line:
perl -Mif::prog='foo,Devel::EndStats::LoadedMods' foo ...
In crontab:
PERL5OPT='-Mif::prog=foo,Devel::EndStats::LoadedMods' # this Perl program will load Devel::EndStats::LoadedMods 0 0 * * * foo some arg # this Perl program won't 1 1 * * * bar other args
use if::prog $prog, MODULE => ARGUMENTS;
is a shortcut for:
use if $0 =~ $prog, MODULE => ARGUMENTS;
The reason this pragma is created is to make it easier to specify on command-line (especially using the -M perl switch or in PERL5OPT).
-M
