Re^2: Logging to web page with Mojolicious and strict

Thanks for your suggestions. Unfortunately I get the same error. Here's a SSCCE. Hopefully this helps.

index.mojo:

#!/usr/bin/perl

use Mojolicious::Lite;
my $logLine;
require './bigFileFullOfSubs.pl';
require './subImWorkingOn.pl';

any '/' => sub {
    my $c = shift;
    $logLine = "";
    subImWorkingOn();
    $c->stash(logLine => $logLine);
    $c->render(template => 'main');
};

app->start;

BigFileFullOfSubs.pl:

sub Log { # Generates nice looking log comment with time.
    my ($LogItem) = @_;

    my $thisLog = "[ $Time ] :: $LogItem\n";
    $logLine .= $thisLog;
}

return 1;

As the error message suggests, your BigFileFullOfSubs.pl won't compile because you have not declared `$logLine` in it. One solution would be to share this variable among your scripts but that would get very messy very quickly. However, since you don't actually need `$logLine` anywhere else, just move the declaration of it out of index.mojo and into BigFileFullOfSubs.pl (outside the subroutine) and you may find this solves your problems.

Perhaps, and I mean this with all sincerity, it's also long overdue that you convert the Perl-4-style "libraries" to real modules. In either case, just store the variable in the library/module that is creating it, and have it provide a subroutine to access it for the template.	[reply]

Point well taken. I've started in on that, I'm about halfway through.	[reply]
