I grepped for a string from a directory of very large files. This took quite a long time (not a problem). When I grepped for a different string from the same files immediately after, the output was MUCH quicker.
My question is, does anybody know why the second grep was so much quicker than the... (1 Reply)

test::without::module
Test::Without::Module(3) User Contributed Perl Documentation Test::Without::Module(3)
NAME
Test::Without::Module - Test fallback behaviour in absence of modules
SYNOPSIS
use Test::Without::Module qw( My::Module );
# Now, loading of My::Module fails :
eval { require My::Module; };
warn $@ if $@;
# Now it works again
eval q{ no Test::Without::Module qw( My::Module ) };
eval { require My::Module; };
print "Found My::Module" unless $@;
DESCRIPTION
This module allows you to deliberately hide modules from a program even though they are installed. This is mostly useful for testing
modules that have a fallback when a certain dependency module is not installed.
EXPORT
None. All magic is done via "use Test::Without::Module LIST" and "no Test::Without::Module LIST".
Test::Without::Module::get_forbidden_list
This function returns a reference to a copy of the current hash of forbidden modules or an empty hash if none are currently forbidden. This
is convenient if you are testing and/or debugging this module.
ONE LINER
A neat trick for using this module from the command line was mentioned to me by NUFFIN and by Jerrad Pierce:
perl -MTest::Without::Module=Some::Module -w -Iblib/lib t/SomeModule.t
That way, you can easily see how your module or test file behaves when a certain module is unavailable.
BUGS
o There is no lexical scoping
CREDITS
Much improvement must be thanked to Aristotle from PerlMonks, he pointed me to a much less convoluted way to fake a module at
<http://www.perlmonks.org/index.pl?node=192635>.
I also discussed with him an even more elegant way of overriding CORE::GLOBAL::require, but the parsing of the overridden subroutine didn't
work out the way I wanted it - CORE::require didn't recognize barewords as such anymore.
NUFFIN and Jerrad Pierce pointed out the convenient use from the command line to interactively watch the behaviour of the test suite and
module in absence of a module.
