# -- TYPING SPEED GAME -- #

#OPTIONAL (but currently implemented):
use List::Util 'shuffle';    #Or use substitute/ don't sort.

# WORD LIST:
#my @words = qw{ fred barney pebbles dino wilma betty };
#Could get different list of words from another file or, like above, just typing them in.
my $file = '/usr/share/dict/words';
open( FIN, '<', $file ) or die("$file");
my @words = map { chomp; $_ } <FIN>;

my @shuffled_words = shuffle(@words);

#Instructions:
print
"This is a game to test how fast you can type these 'words'.\nThe game ends when you get 5 errors or reach the end of the dictionary\n";
print "You can exit by pressing ctrl-c or command .\n";
print "\n	First choose the MAXIMUM number letters you want in the words\n";
print "	Then type the word that shows up:\n";
print "	After typing, press Enter.\n";
print "	Type Enter without any entry to skip the word\n";
print "	Don't forget: Case Matters!\n";

#Begin:
#Max letters
print "\nWhat maximum number of letters do you want?\n\n";
chomp( my $max_length = <> ); #Should check if it's a number? if ($max_length =~ /\D/) {try again}

my $errors = 0;

#time start
my $starttime = time();

#If don't want sort, use `@words` in loop:
foreach (@shuffled_words) {

    #Stop the Game
    if ( $errors >= 5 ) {
        print "Game Over. Too many errors!\n\n";
        last;
    }

    #Main Type Game:
    ## redo comes here ##

            $errors++;
            redo;    # jump back up to the top of the loop
        }
    }

#Post game Report
print "Game Stats:\n";
print "Max word length: $max_length\n";
print "Your current time is $totaltime s, with $errors errors.\n";
print "\nTry again. You didn't get all the words.\n\n";

#Winner?!
print
  "Wow! You went through the entire dictionary! Try a longer word length!\n\n"
  unless ( $errors eq 5 );

#Future:
#Could implement saving highscores by sending to a file... and testing against it's contents
#Add count for skips
#For output: use Term::ANSIColor;
