For the second day of perlukkah, I would like to extend the following script I shall post. In the cleverer parts of this one will see tybalt87's style and idioms, many of which I struggle with as only an intermediate practioner of perl. I won't post output, but what I want to have is this same capability in Russian. Campouts used to be my holy time for my russian crosswords, but 2020 kind of mucked that up. I'm pleased to announce that rain is saturating Clackamas county in Oregon in what would other wise be a hard day outside.

Anyways, let me stop blabbling, and get to the perl of it:

#!/usr/bin/perl

use strict;    # https://perlmonks.org/?node_id=11116556
use warnings;
use Path::Tiny;
use 5.016;

### adding grown-up perl logging

use Log::Log4perl;

# get rid of old one
my $file = '/home/hogan/Documents/hogan/logs/4.log4perl.txt';
unlink $file or warn "Could not unlink $file: $!";
my $log_conf4 = "/home/hogan/Documents/hogan/logs/conf_files/4.conf";
Log::Log4perl::init($log_conf4);    #info
my $logger = Log::Log4perl->get_logger();
$logger->info($0);

my $dict_path  = '/home/hogan/Documents/hogan/my_data/upwords.10';
my $dictionary = path($dict_path);

my @trials = ( '  f   e ', 'w   r  e  ', '  w   r  e', 'h og', );

for my $string (@trials) {
  $logger->info("============");
  say "$string";
  $logger->info($string);
  my @tiles = map +( 'a' .. 'z' )[ rand 26 ], 1 .. 7;
  print "tiles: @tiles\n";
  $logger->info("tiles: @tiles\n");

  my $pat     = join '', map "$_?", sort @tiles, $string =~ /\w/g;
  my $tilepat = join '', map "$_?", sort @tiles;
  my $letters = join '', @tiles, $string =~ /\w/g;
  print "pat: $pat\ntilepat: $tilepat\nletters: $letters\n";
  $logger->info("$pat\ntilepat: $tilepat\nletters: $letters\n");
  my @matches =
    grep { ( join '', sort split // ) =~ /^$pat$/ }
    $dictionary->slurp =~ /^[$letters]{2,}$/gm;

  say "matches are @matches";

  my @places;
  ( $string =~ tr/ /./r ) =~ /(?<!\w).{2,}(?!\w)(?{ push @places, $& }
+)(*FAIL)/;

  @places = grep /\w/, @places;
  use Data::Dump 'dd';
  dd \@places;

  my @matches1 = extension( 1, @places, @matches, $tilepat );
  print "@matches1\n\n";
  say "==============";
  my @matches2 = extension( 2, @places, @matches, $tilepat );
  print "@matches2\n\n";
  say "==============";
}

sub extension {
  my ( $id, @places, @matches, $tilepat ) = @_;
  my @found;
  for my $placepat ( $id == 1 ? @places : map expand($_), @places ) {
    for my $match (@matches) {
      $logger->info("id: $id match: $match");
      $match =~ /^$placepat$/ or next;

      $logger->info("id: $id placepat: $placepat");
      $logger->info("matched: $match");
      my $newtiles = $match & ( $placepat =~ tr/.a-z/\xff\0/r );
      my ($hex) = unpack( 'H*', $newtiles );
      $logger->info("hex is: $hex");
      ( join '', sort $newtiles =~ /\w/g ) =~ /^$tilepat$/
        and push @found, $match;
    }

  }
  return @found;
}

sub expand {
  grep /\w/, glob join '', map { /\w/ ? "{$_,.}" : $_ } split //, shif

Actually, I should post the .conf files.

Let me interject here that I heard the maintainer for this stopped doing so. I think one aspect of such maintenance comes in the form that the rest of us talk about it and use it. I've used it on windows and ubuntu, and it's a lifesaver on the former, and worthwhile stuff on the latter. These are straight from the documentation.

Q1) Does that role need to be filled?

Q2) Where do I find a link to download a modern russian dictionary like the one that google provides for english? I have hundreds of failures I could discuss. Let's not! Let me instead talk about what I need. An official word list for gamers of which there are zillions in Russia. There's millions of them here, and I love going into their shops, getting my torte's and the кроссворд. All words are in modern cyrillic. I'm not aware that's there's an argument about what that consists of, in particular with so many recent crossover words from english. I honestly don't know what they do with orthography anymore when they introduce Putin as Nash Leader. Also, I want what is current like as fresh as the confections I buy, although doing this entire exercise with Church Slavonic sounds like a fun task for Perlukkah 2021.

I think it'll be interesting to see what accomodation we have to make for the cyrillic. If we can't find sources from within Russia, well they've been exporting their language quite successfully, so I can well imagine that I could get qualified responses from eastern europe in particular where russian instruction was obligatory for many years. Under normal circumstances, I might waltz into the local libraries with this question, which have extensive russian holdings, events and staff, but not in lockdown, which is where we are on the covid scale now. Hence the need for perlukkah 2020.

Now I've got to answer marto in yesterday's question. That write-up is harder.

"Yay, it's raining for perlukkah."
