ikiwiki/doc/bugs/Hyperestraier_search_plug-in_defective.mdwn

The map() function used in the hyperestraier search plug-in doesn't work as intended as ilustrated by this simple script:

    #!/usr/bin/perl -w
    use strict;
    
    my @foo = (
    	[ qw/foo bar baz/ ],
    	[ qw/fee faa fum/ ],
    	);
    
    # similar to current ikiwiki code (defective):
    my @bar = map { "/path/to/$_" foreach @{$_} } @foo;
    
    # this works:
    #my @bar = map { map { "/path/to/$_" } @{$_} } @foo;
    
    foreach (@bar) {
    	print "$_\n";
    }

Expected output:

    /path/to/foo
    /path/to/bar
    /path/to/baz
    /path/to/fee
    /path/to/faa
    /path/to/fum

Current output:

    Useless use of string in void context at perl-map.pl line 10.

[[bugs/done]] ; thanks for the patch. Suprised it worked at all since the
bad code was added (did it?) --[[Joey]]

Thank you for accepting my patch. I can't see how it could ever have worked
with the previous code, no. --[[Brix|HenrikBrixAndersen]]
