Here is a tic-tac-toe board:

   a     b     c
      |     |     
1  -  |  -  |  -  
      |     |     
2  -  |  -  |  -  
      |     |     
3  -  |  -  |  -  
      |     |     

Given a set of moves, print the board with the tokens on.

Input will be taken in as moves separated by spaces, with each move being:

  • First, the token that's going
  • Next, the letter of the column it is moving on
  • Last, the number of the row it is moving on

Note that normal tic-tac-toe rules don't matter.

Also, there is no need to print the letters and numbers.

For example, the input Ob2 Xc2 Ob3 Xa1 would result in

     |     |     
  X  |  -  |  -  
     |     |     
  -  |  O  |  X  
     |     |     
  -  |  O  |  -  
     |     |     

Remember, this is , so the code with the smallest number of bytes wins.


Here is a Stack Snippet to generate both a regular leaderboard and an overview of winners by language.

To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:

# Language Name, N bytes

where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:

# Ruby, <s>104</s> <s>101</s> 96 bytes

If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:

# Perl, 43 + 2 (-p flag) = 45 bytes

You can also make the language name a link which will then show up in the leaderboard snippet:

# [><>](http://esolangs.org/wiki/Fish), 121 bytes

    \$\begingroup\$ @EriktheGolfer cumbersome? This input format is plain and obvious \$\endgroup\$ – edc65 Oct 8 '16 at 12:45
  • \$\begingroup\$ @edc65 I meant that, I want to get input in any format, not just this one, but I guess it's late by now. I think you mean it's visually clear, but I couldn't handle it at all. Why spaces and not some other separator for example? \$\endgroup\$ – Erik the Outgolfer Oct 8 '16 at 13:58

    \$\begingroup\$ @EriktheGolfer don't take me wrong, but if your super extra esoteric language cannot handle blank spaces, too bad ... you'll have to use something else just this time. \$\endgroup\$ – edc65 Oct 8 '16 at 14:02

    \$\begingroup\$ @edc65 For example, in Sesos it would be pretty difficult to even load the input data. I would prefer a list of integers (three ints for one move), like 1 2 3 for Xb3 (doesn't have to be exactly that). \$\endgroup\$ – Erik the Outgolfer Oct 8 '16 at 14:06

  • \$\begingroup\$ for y in '123' -> for y in'123'. Also, what xnor said: you can make your function a one-liner, using ; to separate statements. Using all of these golfing tips, you can golf 6 bytes. \$\endgroup\$ – Erik the Outgolfer Oct 8 '16 at 9:55

Python 2, 112 bytes

s=input()+'- '
r=3;exec"print'|'.join([' '*5,'  %s  '%s[s.find(c+`r/3`)-1],'_'*5][r%11%3]for c in'abc');r+=1;"*9

Nine rows are printed corresponding to row indices r. The row index is counted up from 3 to 11 in an exec loop. Each row consists of vertical lines | joining three 5-character segments that cycle between:

  • Five spaces
  • Two spaces, a player symbol, then two spaces
  • Five underscores

The type is made to cycle with r%3, except the last row has spaces rather than underscores, achieved with r%11%3.

To find the player symbol for the current cell, we look at the row number r/3 and the column letter c from "abc". We concatenate them to make a two-character string like b3, find the index of it in the input string, and then take the symbol (X or O) one index earlier. If neither player played there, the find will default to -1, which decrements to -2. We hack s[-2] to be - by appending two characters when we take input.


PHP, 187 Bytes

<?for(;$i++<162;)$s.=$i%18?($i%6?($i<144&&$i%54>36?"_":($i<144&&$i%54>18&&$i%6==3?"-":" ")):"|"):"\n";foreach(explode(" ",$_GET[a])as$t)$s[20+6*(1+($t[1]<=>b))+54*($t[2]-1)]=$t[0];echo$s;

Takes the input as string. If I could use an array it can be reduce to $_GET[a] instead of explode(" ",$_GET[a])

207 Bytes

<?foreach(explode(" ",$_GET[a])as$t)$a[(1+($t[1]<=>b))+3*($t[2]-1)]=$t[0];for(;$i++<162;)$s.=$i%18?($i%6?($i<144&&$i%54>36?"_":" "):"|"):"\n";for(;$x<9;)$s[18+54*(($x/3)^0)+2+6*($x%3)]=$a[+$x++]??"-";echo$s;

The simplest idea to create this 194 Bytes

<?for(;++$i<10;)$s.=($i==9||$i%3?($i%3==2?"  -  |  -  |  -  ":"     |     |     "):"_____|_____|_____")."\n";foreach(explode(" ",$_GET[a])as$t)$s[20+6*(1+($t[1]<=>b))+54*($t[2]-1)]=$t[0];echo$s;

Mathematica, 205 bytes

StringReplacePart[a="     |     |

This would be way shorter if I could use the built-in... (92 bytes)

Autovim, 110 bytes (not competing)

Test driving Autovim... This is pretty much a Vimscript answer. Not competing because Autovim is still being developed.

ñ5i ␛a|␛ÿp3hr-phv0r_⌥v$kkyPPy2jPP$⌥vG$xGđkÿjp

To run it:

./bin/autovim run tictactoe.autovim -ni -@m "Ob2 Xc2 Ob3 Xa1"


execute "normal 5i \<esc>a|\<esc>yyp3hr-phv0r_\<c-v>$kkyPPy2jPP$\<c-v>G$xGddkyyjp"
for @n in split(@m)
execute "normal gg0".(@n[2]*3-2)."j".((char2nr(@n[1])-96)*6-4)."lr".(@n[0]).""

Explanation to follow if there is interest :)
