I am so sick of the Three's, 1024, 2048 posts on Hacker News, but I upvoted this because of sed :P

Sed awesome.

Also, disappointed no one has blatantly embedded https://github.com/progranism/Bitcoin-JavaScript-Miner to put all this time wasting to good u$e.

Sadly that javascript miner is stupidly slow. You could have a top Hacker News post and still only make pennies.

Not even that really. You might get a single difficulty 1 share or two, worth literally less than the maximum precision BTC allows.

You didn't get the joke. That's okay.

We just need now the 2048 in assembler, and we'll be done!

Just joking, I love these and I'm unemployed. Keep'em coming!

Well, there's this: https://github.com/Sanqui/2048-gb

It was posted on HN but didn't really take off, sadly: https://news.ycombinator.com/item?id=7434529

I bet had they left "Show HN: " off, it would've gained more traction. I have several theories behind that:

1) It looks more like a discovery.

2) It doesn't look like a self promotion.

3) The point of the article is at the beginning. I.e. a certain percentage don't read past "Show HN".

Again, just theories. No idea if this is really the case. But I don't remember many (maybe any) of the other 2048 clones making it to the first page being "Show HN" submissions.

The one that's done for Atari is in assembly. I made one in Prolog last weekend as an exercise since I'm learning Prolog. I figured it was a matter of time till the variation became about language implementation.

I think this game is a bit different than http://gabrielecirulli.github.io/2048/ Take a look at this situation:

   ___________________
  |___2|____|____|____|
  |___2|____|____|____|
  |___2|____|____|____|
  |____|____|____|____|
in the original the result of going up would be

   ___________________
  |___4|____|____|____|
  |___2|____|____|____|
  |____|____|____|____|
  |____|____|____|____|
but in this game it's

no score too! :(

how am i suppose to know when i break my own record [i.e. 3012 - never got passed 512 on the tiles]

themattrix
I'll look into adding this. (I think I'll have to add it to the bash wrapper.)
themattrix
Score is now implemented -enjoy!
scope
thanks!

edit: you broke it :(

themattrix
Fixed! The score is now calculated as the sum of all merge results (like the original game), instead of the sum of all cells (like I was doing).

As a bonus, the score calculation is now done in pure sed.

If you notice any other issues, please let me know!

scope
thanks

One final gameplay tweak: there's now a 90% chance that a newly-spawned tile will be a "2" and a 10% chance that it will be a "4".

The gameplay should now be identical to the original 2048.

themattrix
This bug is now fixed! Thanks for pointing it out!

Have someone made Emacs version? Isn't it more easy to write it in elisp compared to sed.
RBerenguel
Well, writing in sed has essentially the "heh, look what I did in sed!" value. Elisp would be a far more simple place to build it (we already have tetris there, there's even a very old simple version of Elite in emacs lisp!)
calebm
Yep. "Real programmers write games in sed".
discardorama
I'm sure Emacs has a "unix mode" hidden in there somewhere. Inside it, I bet there's a full complement of GNU utils. Sed should be in there somewhere.
robinson-wall
> Note for OS X users: The version of sed installed has different options than the Linux one. Notably, it does not have the extended-regex option -r. I recommend building the latest version from here: http://sed.sourceforge.net/

The option is there, just different: -E (the same as grep)

celebril
Why doesn't Apple just ship with standard GNU utils?

They are the de facto standard. Having the need to compile all these basic stuff for any scripting to be portable is a nightmare.

Spiritus
I believe it's a licensing issue, could be completely wrong though.
13throwaway
Apple has chosen not to ship any GPLv3 code.
gkya
If your well-beloved GNU coreutils did not breach every POSIX standard and add new flags to every program, no such problem would exist. Seriously, I do not know whether Mac OS is using a custom implementation of UNIX utilities, or distributin BSD coreutils, but I know that it is a licensed, certified UNIX.
celebril
UNIX certification means nothing if the utils are intentionally outdated and incompatible with the de facto UNIX-like implementation due to petty licensing concerns.

At the end of the day, whether some script works is the issue, not a UNIX branding.

james2vegas
Except Mac OS X is a de jure UNIX implementation, and concern about GPLv3 is not petty.
LukeShu
GNU sed 4.2.0 and up also support -E for compatibility with BSD sed (though this is undocumented).
gwu78
I also like his poker hand sed script.

Best part is he uses BSD sed. No newlines as patterns.

We use tr(1) for that.

Hey Matt... I mean "Sed and Awk the great" :)
