Since it's now pretty unreadable, a basic explanation:
- we tile the space top left to bottom right
- we draw it as basically 6 diagonal lines that repeat every 8 characters: 2 solid lines, and 4 that are "dashed" (two characters, then two spaces...)
- the
C=... stuff is to limit drawing of some of the lines to within a bounding box
- to save a lot of characters, we deliberately add numbers to make the expressions for the upwards and downwards lines extremely similar
- then, put the expressions themselves into a sparse array
[1,,C&&...], which we look up into. If there is a truthy value, we draw the appropriate character.
-
for(c=r=a='';r<16;c++>22&&(r++,c=0,a+=`
`)) // basic grid tiling
C=c%22>1&&r%14>1, // are we not near the edges
q=[1, // a solid line that always draws
, // a line that never draws
C&&r&2, // a line that draws if not near the edge, and if on the correct "dash" (r&2)
,,,
C&&~r&2, // if not near the edge, and on the opposite "dash" (~r&2)
,1 // the opposite diagonal line that always draws
],
a+=q[c+5+r&7]?'/' // compute which upward line we're on, check whether to draw it
:q[r-c+20&7]?'\\' // do the same for the downward line
:' ' // otherwise draw a space
Maybe this explanation didn't help. :)
