Thanks all for replies,

I combined the examples Luke gave to get a pretty decent list that prints out with a big top banner for the next day. Knowing what day it is right when you wake up is not something I'm equipped for, as I just make too many mistakes. It's a good thing that nothing I take in the morning keeps me alive, because I might forget once a week. I'm convinced that a checklist is the ticket. There are certain things I'm gonna want to have on this list every day. Maybe I should give them their own space.

Q1) How does one load up on the fonts that are out there like the DejaVu one that I had to comment out and use a corefont instead?

If I delete the hash-commenter on the first save to my windows partition, I get this error:

Unable to open /media/fred/Windows8_OS/Documents and Settings/Fred/Doc

I suspect that "I" as the perl executable don't have the proper permissions to do what I can do by copying and pasting with nautilus after the script is run. I can hardly express in words how fatigued I am in getting documents to windows so that I can print it, and I don't believe there's linux drivers for my hp 4620 printer (I looked today again). Q2) How do I convince my OS that I'm allowed to write in the directory? Or am I cobbling it together wrong with Path::Class?

Finally, can someone talk me through what the map is doing in this script:

$ perl cal1.pl

One of the items that happy people do every day is read. A person could read perl and check it off....

It's good that you try to figure out the workings of the code by inserting print statements in it. It's always a good start.

As to your third question:

say "month are @month";

month are ARRAY(0x1fa34e0) ARRAY(0x1fa3678) ARRAY(0x1fa41d0) ARRAY(0x1
+edd548) ARRAY(0x1edd5f0) ARRAY(0x1edd698)
[download]

You were expecting the elements of the array, and here they are, still, they look a bit strange. Thing is, @month is an array of arrays (to be more specific, an array of array references). Data structures such as these are best viewed with Data::Dumper.

use Data::Dumper;
say Dumper \@month;
[download]

You will see, that your array looks like this:

$VAR1 = [
          [ undef, undef, undef, undef, undef, undef, 1 ],
          [ 2, 3, 4, 5, 6, 7, 8 ],
          [ 9, 10, 11, 12, 13, 14, 15 ],
          [ 16, 17, 18, 19, 20, 21, 22 ],
          [ 23, 24, 25, 26, 27, 28, 29 ],
          [ 30, undef, undef, undef, undef, undef, undef ]
        ];
[download]

Now, you could just print it as is, with

foreach (@month) {
  say join " ", @$_;
}
[download]

The code above means "iterate over the weeks of @month, treat each week as an array ( that's what @$_ does ), and print this array with one space between each element".

It you try it, it will look like a mess, because each element will occupy zero, one, or two characters, and the days will not align under each other.

The problem you are facing is this. When you are printing, you have an array that looks like this:

( undef, 2, 3, 10 )
[download]

and you want an array like this:

( '   ', ' 2 ', ' 3 ', '10 ')
[download]

with every element taking up exactly three spaces.

It's a good rule: when you want to transform one array into another array, you should be thinking about map. map iterates over the array, and maps the value of the original element ( $_ ) to the value you want in your target array. You can read about map in Map: The Basics, or here.

map, as used in your example, does exactly this:

foreach (@month) {
  say map { 
        if ($_) {   # if the element is not undef
            sprintf "%2d ", $_; 
            # format it so it takes 2 spaces, and add one space to it
        }
        else {      # if the element is undef
            '   ';
            # replace it with 3 spaces
        }
    } @$_;
}
[download]

It looks different in your example, because it uses the ternary operator as a shorthand for the if ... else expression.

Now, as to your first question, the line:

my $font = $pdf->ttfont('DejaVuSans.ttf');
[download]

assumes the font file is in the same directory. The argument for ttfonf is the path to the file. You can of course use the core fonts, but I'm afraid the Russian characters will not work (this was the reason I used ttfont in my example).

ad Q2: are you sure that the "physical" name of that directory is "Documents and Settings"? Windows newer than Vista have some weird logic to make it appear so in Explorer, but the name on Disk changed to "Users", and trying to access the "logical" name results in "permission denied" rather than "not found"...
