Following this trial by cavac, the next post I looked at was Print %HoH values

So, I thought I would try out ChatGPT to debug the code in that question. I'll leave you to decide how well it did but I feel it would, at the very least, help me with starting the debugging process. It failed to suggest adding use strict.

------------------------------------------

It looks like there is a syntax error in the Perl code that might be causing the issue with the output not being displayed properly. Specifically, the "+" symbol at the end of the line in the inner for loop seems to be an error. Here is the corrected code:

for my $dia (sort keys %HoH) {
        print "<br>$dia: <br>";
        for my $horarios (sort keys %{$HoH{$dia}}) {
                print "$horarios=>" . $HoH{$dia}->{$horarios} . "<br>"
+;
        }
}

print "VALUE:<br>";
print ${"2023-01-01"}{"00:00"};

In the last line, the code is attempting to print the value of the key "00:00" in the hash associated with the key "2023-01-01". However, it is not clear from the code snippet whether this key exists in the hash %{"2023-01-01"}. If this key does not exist, the output will be undefined.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
