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.
