Re^2: Golf: Seven segment display

[PrakashK]

Applying the ...=~/./g trick (which you already used once inside the map) again:

sub w{for$;(-2..0){say map{substr'   _ _|_  |_| |',2*ord(('u$SR,Z]dmj'=~/./g)[$_])>>-3*$;&14,3}$_[0]=~/./g}}

[brx]

I think my idea is a "cul-de-sac" but this is a little bit shorter (7 char.).

sub w{for$;(1005,924745596,341831533){say map{$;>>$_&1?/../?'|':_:$"}m
+ap{$_+20,$_,$_+10}$_[0]=~/./g}}

a few obvious optimizations:

say map$'&2**$_?$_>9?'|':_:$",map{2 .$_,$_,1 .$_}split!//,"@_"for 1005,924745596,341831533

I'd say the use of $' is less than obvious. Nice work btw.

The shortest solution I know (not my own creation):

for$;(0..2){say map{substr'   | |_|_ _ _|',vec('0123456789abcdef',$;.$
+_,4),3}"@_"=~/./g}

where '0123456789abcdef' is to be substituted with "\x09\x99\x90\x99\x99\x13\xBB\x75\x17\x55\x15\xB7\xB1\x15\xB5". When the \x codes are replaced with the actual characters, it comes out two characters shorter than the solution above. (Not very elegant, though.)
