Subject: Re: [SOLUTION] Ruby Quiz #14 LCD Numbers ( solution #2 )

Thanks Jannis Harder found the bug.
It is still 349 bytes program:
( the bug is on "u[x==1?2:5]<0", it should be "u[x==1?2:5]<o", typo
error "o" instead of "0")

s=$*.index("-s");s=(s ?$*.slice!(s,2)[1].to_i: 2)
i=$*.join.split("").map{|x|x.to_i}
d,="7krtt1r30v/s".unpack("m")[0].unpack("B*")
f=" "
a,b=f*s,f+"-"*s+f
c,e,o="|",a+f+f,49
y=([0]*5).map{""}
i.each{|z|u=d[z*7,7]
3.times{|x|y[x*2]<<(u[x*3]<o ?e:b)<<f}
[1,3].each{|x|y[x]<<(u[x==1?1:4]<o ?f:c)+a+(u[x==1?2:5]<o ?f:c)<<f}}
y[1,1]*=s
y[2+s,1]*=s
puts y
