sub do_funky_tag_thing { my ($text1, $text2) = @_; # Build the command-line args from the web-service # args. Some funky logic here.. my %args; $args{'-opt1'} = $text1 if defined $text1; if (defined $text1 and defined $text2) { $args{'-opt2'} = process_text($text2); } # Log the command to L4P for audit purposes. my $external_command = 'tag '; for my $opt (keys %args) { $external_command .= $opt.' '.shell_escape($args{$opt)) } get_logger->info( "Running external command: $external_command"; ); # Now run the actual command.. with no reliance on # shell_escape() system('tag',%args); }

[Eily]: hum, tied scalar, generates a new array when derefed ? :D
[Corion]: choroba: Ah, when doing a shallow copy, I prefer [ @$var ] - I think \@$var might return the same reference instead of a reference to a fresh copy
[Corion]: perl -wle "my $ar = [1,2,3]; my $br=\@$ar; print qq($ar / $br)" confirms this to me
[karlgoethebier]: "discovered" this to sum an array: perl -E 'say scalar map {1 .. $_} (1..3);'
[Corion]: karlgoethebier: Hahaha :)
