loop, insdide do loop. do twice?

[Bigmac Turdsplash]

mply = 0
body = "just some data"
proof = 100
VALUE=""
list = ['line1','line2','line3']

foreach(list) do |block|
while mply < 3
puts mply.to_s+block+VALUE
if body.bytesize > proof
print("writing to log.html #{VAULE}")
end
mply = mply + 1
end
mply = 0
end
VALUE="XXXX"

# if you run this example above, you should see something printed like
this
# 0line1
# 1line2
# 2line3


now what im trying to do could easly be done with just doubling this
code but that is messy and i need to clean it up...

how can i produce this output and keep things short and simple
# 0line1
# 0line1XXXX
# 1line2
# 1line2XXXX
# 2line3
# 2line3XXXX

im in irc /server freenode #ruby if some one could help me or just
respond here... this one has me scratching my head for a few days...

mply =3D 0

You can use #times for iteration.

=A0puts mply.to_s+block+VALUE
=A0 =A0if body.bytesize > proof
=A0 =A0 =A0print("writing to log.html #{VAULE}")

Note that print does not append a line terminator (as puts does).

=A0 =A0end
=A0 =A0mply =3D mply + 1
=A0end
=A0mply =3D 0
end
VALUE=3D"XXXX"

Reassigning a constant is a bad idea.

This all can be solved with nested iterations - you just need to stack
your loops appropriately: the outer loop iterates what changes most
infrequently ("list" in your example). The next inner loop must
iterated over next infrequent changing item etc. Also, you can use
#each_with_index to get the index of each element in your list.

%w{line1 line2 line3}.each_with_index do |block, mypl|
['', 'XXX'].each do |suffix|
puts "#{mypl}#{block}#{suffix}"
puts "Writing to log.html #{suffix}" if body.bytesize > proof
end
end
