Re: Matching Dates

Without seeing the actual code I can't help you with the details, but the general idea is correct:

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

use enum qw( DATE TIME );

my @reservations = ([ '2020-03-21', '2:00 pm' ],
                    [ '2020-03-21', '3:00 pm' ],
                    [ '2020-03-22', '2:00:pm' ]);

my $last_date = "";
for my $reservation (@reservations) {
    print $last_date eq $reservation->[DATE] ? ' ' x 10 : $reservation
+->[DATE];
    say ' ', $reservation->[TIME];
    $last_date = $reservation->[DATE];
}
[download]

Output:

2020-03-21 2:00 pm
           3:00 pm
2020-03-22 2:00:pm

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

I wasn't familiar with enum in perl as opposed to C, so I found this interesting to replicate and then supplement from the examples given in enum.pm: `date is 0 time is 1 2020-03-21 2:00 pm 3:00 pm 2020-03-22 2:00:pm 6 is SIX pref is 2 date is Months_Feb 1 c is 22` [download] #!/usr/bin/perl use warnings; use strict; use feature qw{ say }; use enum qw( DATE TIME ); say "date is ", DATE; say "time is ", TIME; my @reservations = ( [ '2020-03-21', '2:00 pm' ], [ '2020-03-21', '3:00 pm' ], [ '2020-03-22', '2:00:pm' ] ); my $last_date = ""; for my $reservation (@reservations) { print $last_date eq $reservation->[DATE] ?

I wasn't familiar with enum in perl as opposed to C, so I found this interesting to replicate and then supplement from the examples given in enum.pm:

date is 0
time is 1
2020-03-21 2:00 pm
           3:00 pm
2020-03-22 2:00:pm
6 is SIX
pref is 2
date is Months_Feb 1
c is  22

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

use enum qw( DATE TIME );

say "date is ", DATE;
say "time is ", TIME;

my @reservations = (
  [ '2020-03-21', '2:00 pm' ],
  [ '2020-03-21', '3:00 pm' ],
  [ '2020-03-22', '2:00:pm' ]
);

my $last_date = "";
for my $reservation (@reservations) {
  print $last_date eq $reservation->[DATE] ? ' ' x 10 : $reservation->
+[DATE];
  say ' ', $reservation->[TIME];
  $last_date = $reservation->[DATE];
}

use enum qw(Forty=40 FortyOne Five=5 Six Seven);

# Yes, you can change the start indexs at any time as in C
say "6 is ", "SIX";

use enum qw(:Prefix_ One Two Three);
## Creates Prefix_One, Prefix_Two, Prefix_Three
say "pref is ", Prefix_Three;

use enum qw(
