  1. POPerl: mocking -d -f and friends. How to put them into CORE::GLOBAL
    text
    copied!<p>The CORE documentation has shown me how to merrily mock various built Perl functions. However, I'm not really sure how to replace '-d' &amp;c. with my methods. So this is really just a question on how do i replace a function with a dash in it in CORE::GLOBAL.</p> <p>A manual reference would be nice.</p> <pre><code>package Testing::MockDir; use strict; use warnings; use Exporter(); use Symbol 'qualify_to_ref'; *import = \&amp;Exporter::import; our @EXPORT_OK = qw(SetMockDir UnsetMockDir); our %EXPORT_TAGS = ( 'all' =&gt; \@EXPORT_OK, ); my %path2List = (); my %handle2List = (); BEGIN { *CORE::GLOBAL::opendir = \&amp;Testing::MockDir::opendir; *CORE::GLOBAL::readdir = \&amp;Testing::MockDir::readdir; *CORE::GLOBAL::closedir = \&amp;Testing::MockDir::closedir; ######################### the "-" is really the problem here *CORE::GLOBAL::-d = \&amp;Testing::MockDir::mock_d; # This does not work &lt;&lt;&lt;&lt;&lt; } sub mock_d ($) { die 'It worked'; } sub SetMockDir { my ($path, @files) = @_; $path2List{$path} = [@files]; } sub UnsetMockDir { my ($path) = @_; delete $path2List{$path}; } sub opendir (*$) { my $handle = qualify_to_ref(shift, caller); my ($path) = @_; return CORE::opendir($handle, $path) unless defined $path2List{$path}; $handle2List{$handle} = $path2List{$path}; return 1; } sub readdir (*) { my $handle = qualify_to_ref(shift, caller); return CORE::readdir($handle) unless defined $handle2List{$handle}; return shift @{$handle2List{$handle}} unless wantarray; my @files = @{$handle2List{$handle}}; $handle2List{$handle} = []; return @files; } sub closedir (*) { my $handle = qualify_to_ref(shift, caller); return CORE::closedir($handle) unless defined $handle2List{$handle}; delete $handle2List{$handle}; return 1; } 1; </code></pre>
