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

   ___________________
  |___2|____|____|____|
  |___4|____|____|____|
  |____|____|____|____|

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

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]

I'll look into adding this. (I think I'll have to add it to the bash wrapper.)

Score is now implemented -enjoy!

thanks!

edit: you broke it :(

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!

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.

> 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)

GNU sed 4.2.0 and up also support -E for compatibility with BSD sed (though this is undocumented).

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.

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.

UNIX certification means nothing if the utils are intentionally outdated and incompatible with the de facto UNIX-like implementation due to petty licensing concerns.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.

Except Mac OS X is a de jure UNIX implementation, and concern about GPLv3 is not petty.

I believe it's a licensing issue, could be completely wrong though.

Apple has chosen not to ship any GPLv3 code.

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

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.

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.

There is Sokoban in sed too.

For who is interested in other games written in sed.

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.

Author here - glad you like it! I actually found the poker hand identifier more challenging to write than 2048, but I also tried to make it as compact as possible.

Have someone made Emacs version? Isn't it more easy to write it in elisp compared to sed.

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!)

Yep. "Real programmers write games in sed".

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.

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

You've revealed my secret identity!
