I'm having weird amount of fun while tinkering with this script, thanks again to Gede (and sorry windows folks, I'm not going to learn how to do all that in python - perl, bash and bunch of linux commandline utilities is what you get). 
  First, you have to log TNP output. -u is needed otherwise output will be buffered and you only get notification after 4096 bytes of output accumulate, which is far too late: 
 while true; do python3 -u ./the_napping_gamer.py 2>&1 | tee -a the_napping_gamer.log; if ! sleep 10; then break; fi; done  
 If you want to know what games are part of insomnia, or what exactly to put into your wishlist.txt (should you include ":" or not etc.): 
 cat the_napping_gamer.log | perl -n -e'if (m/NEW! "(.*)"/) { print "$1\n"; }' | sort | uniq  
 You can also redirect output of above commands to a file, say "list_snapshot", let it run for a while and then see what new games GOG added to the insomnia since then: 
 cat the_napping_gamer.log | perl -n -e'if (m/NEW! "(.*)"/) { print "$1\n"; }' | sort | uniq | cat - list_snapshot | sort | uniq -u  
 And finally, if you want to know how much money GOG got from insomnia (only estimate - because regional prices, nobody probably has the complete log, and the log will contain duplicates around restarts/crashes): 
 #!/usr/bin/env perl  
 my $totalPrice = 0; 
 my $totalItems = 0; 
 my $lastGame = '';  
 while ($_ = <STDIN>) { 
 if (m#\d{2,2}:\d{2,2}:\d{2,2}\s*"([^"]*)"\s*[A-Z]{3,3}\s*([0-9.]*)\s*\d+/(\d+)#) { 
 if ($1 ne $lastGame) { 
 $lastGame = $1; 
 $totalItems += $3; 
 $totalPrice += ($3 * $2); 
 } 
 } 
 } 
 printf "total sales: $totalItems for $totalPrice \$, average %.2f\n", ($totalPrice / $totalItems);  
 Also, a small bug: 
 16:51:51 NEW! "reus" at USD 1.99 (-80%) 16/25 copies ('
https://www.gog.com//game/reus',) 
 15:51:51 "reus" USD 1.99 16/25 
 You may nap for 0.8 more minutes (15:52:39). I'll stand guard! Next peek in 30 seconds. 
 The first timestamp respects my UTC offset, second does not.  
 EDIT: bug in sale summary script
