Kindly seeking assistance in rendering images (any static file from /public) in a default Mojolicious-Hypnotoad-Nginx setup. Following the standard guides, this setup successfully renders the default welcome page. However adding one exception: a .png image to this page, it is not rendered, even the favicon.ico doesn't appear.

There is mention of "hooks" needed to correct for the workings of a Reverse Proxy, but after a long search one doesn't find a clear full example -- particularly for Nginx.

The welcome.html.ep has this simple addition: . It appears alone as an image when one enters this url: http://example.com/tree.png

Can you please help to fix?

I have a string that has the form 'a:b:' where 'a' and 'b' are both numbers. How do I drop the second colon, or convert it to // ?

Hello again.

I've got a script that uses named capture groups to parse file records. The record format is always the same (four fields wide, colon separated), just like a passwd file (except for the number of fields).

For example:

0:1:bob:Bob
1:1:bob:Bob
1:0:alice:Alice

You get the idea. At first I used to split it, but later I came to the conclusion that using a regex with named groups could provide a more understandable code. The (simplified) example below might help you get the picture.

if (/^(?<type>[01]):(?<valid>[01]):(?<name>[^:]+):(?<comment>[^:]+)$/)
+ {
    print "Key name: ", $+{name}, "\n";
    print "Key Comment: ", $+{comment}, "\n";
    print "Not valid\n" unless $+{valid} || !$+{type};
} else {
    print "Malformed input: $_\n";
}
[download]

Now, I've noticed (according to perlretut) that named capture groups were introduced in Perl 5.10. I don't expect the script to run in older versions, but would it be wise to use v5.10 pragma?

Would it have any unwanted side effects? I'm not using any of the features of the bundle, just wanted to state that version 5.10 is required. Is that a good idea?

Is there something strange about the way return treats conditions?

I have this and it doesn't work as expected...

sub get_ids {
    my ($self, %attrs) = @_;
    
    # Do stuff...

    my %result;
    # $result{'message'} = '';
    if ($self->{'error'}) {
        $result{'status'}  = 'error';
        $result{'message'} = $self->{'error'};
    } else {
        $result{'status'}  = 'success';
        $result{'api-key'} = $self->{'api-public'};
        $result{'session'} = $intent_id;
    }

    return encode_json(\%result) if lc($attrs{'format'}) eq 'json';
    return $result{'message'} or "$result{'api-key'}:$result{'session'
+}";   # <- line 229
    return "SOMETHING";
}

Can you explain why this is not behaving as expected?

As an aside, in searching for an answer I found this post -> Useless use of string in void context
There it is suggested that Perl reports the wrong line number for this warning so it is quite possible that I'm actually looking in the wrong place!

Searching CPAN I was rather surprised that the only general modules for connecting to LinkedIn seem to be WWW::LinkedIn and Net::Linkedin::OAuth2 - both of these date from before Microsoft acquired LinkedIn 5 years ago...unbelievable that it is that long ago!

Since the 5th April, Hootsuite have reduced the number of scheduled posts permitted on free accounts down to just 5 and we don't use the other features to warrant the paid price tag. We already have an automated Twitter scheduler and I want to add LinkedIn to it so just need something to authenticate, read the timestamp of the latest post and be able to create a post containing media.

Before I write something to do this, are there any modules available or should I try out the modules above despite their age?

A module I am creating has a blessed hash ref as is common. One of the hashes is a reference to an array of anonymous hashes created like so:

sub new {
    my $class = shift;
    my %attrs = @_;
    
    my @products = ({
        'id'            => 0,
        'name'          => 'Test',
        'description'   => 'Some test data',
        'qty'           => 1,
        'price'         => 1000,
    });
    $attrs{'trolley'} = \@products;
    
    return bless \%attrs, $class;
}
[download]

What is the best way to do this?
Both of these push lines appear to work identically in testing

sub add_product {
    my ($self, $product_data) = @_;
    # create $new_product hasfref
    push $self->{'trolley'}, $new_product;
    push @{$self->{'trolley'}}, $new_product;
}

Is there a practical difference and is there a 'best' option to use?

Hi. I need feedback on this... In order to run a Perl program, I must check for the availability of another program (i.e. it's in the PATH). So I've created a subroutine for this (which returns 0 for "not found" and 1 for "found"), and I'm not sure if this is the best option. Here's the code:

sub available {
    my $program = shift;
    for my $pathdir (split /:/, $ENV{PATH}) {
        return 1 if -x "$pathdir/$program";
    }
    return 0;
}

I'd like to know if it's inefficient, and if there's a core module that already takes care of such tasks. Found nothing related on the FAQs.

Is the problem the emoticon? If so, how can I filter these out?

I am trying to add the filename to the end of each line in my files. I tried a few solutions but none seem to work and this is what I have. I am not sure what I am missing or what is wrong.

  open OUT, '>', "Update/$in" || die "can't open file Update/$in";
my @file = @in
while (my $file = <IN>) {
    my $line = $_;
    $updateline = $line . $file;

Whenever I browse Selected Best Nodes, I notice that I miss the create date that is included in "Super Search" results, "Nodes You Wrote", etc. Given that Selected Best Nodes may return postings that may be two decades old, the create date gives some context for the postings.

So I propose to add the create date to Selected Best Nodes.

Effective today, the section of PerlMonks known as "Categorized Questions and Answers" is no longer in service. The section page is a tombstone. It is no longer possible to post Categorized Questions or Answers. It is also not possible to search such posts via Super Search. It wouldn't be useful anyway, because all of the posts which were Categorized Questions have been converted into SOPW posts. Likewise, all posts which were Categorized Answers have been converted into replies to those SOPW posts. In each case, the name of the CatQA 'section' in which the Question was placed has been added to the SOPW post as a keyword.

The intent of the CatQA section will, going forward, be fulfilled by a new system, whereby "good" questions (in SOPW) and their "best" answers will be given a special flag, as well as relevant keywords.

Some documentation and linkage changes remain to be made. If you see any, feel free to sent a msg to SiteDocClan, pmdev, or gods, depending.

For more information on this change, see prior discussion: RFC: Better Best Answers Gets Real
