Writing to a file help

[JeremyWoertink]

I am trying to read 1 file then create another file from that 1. My
problem I am having is that my file is not being formated the same way
I am telling it. So for example I have

line_a = %{#{i.to_s.rjust(6, "0")}|#{array[0]}\|#{array[1]} #{array[2]}
\|#{array[3]}\|#{array[4]}|#{array[5]}|#{array[6]} #{array[7]}|
#{array[8]}|\n}

out_file.write(line_a)


the output is

000001|array0array1array2array3array4array5array6
| |||| ||


so basically my pipes and spaces are being appended to the end of my
string after the "\n"


any ideas?

ok, so it seems that it is not splitting the line into an array. so
what looks to be my array0-6 is actually just array[0]. So, my next
question is how do I split a line by tabs?

I was using array << line.split("\t"), but that isn't working.

Ideas?

thanks,

HAHA, i'm dumb.. sorry, I forgot that using split returns an array, so
I was appending an array to another one. WOW.... time to lay off the
VB for a while and get my head back in some ruby.


OMG.....

Your split should work. Take care with your Array though. Array#<<
appends the object you give it to an Array. String#split returns an
Array so what you end up with is an Array which *contains* the Array
generated by split. Perhaps Array#+ is what you need?

irb(main):009:0> array = []
=> []
irb(main):010:0> string = "hi\tthere"
=> "hi\tthere"
irb(main):011:0> string.split("\t")
=> ["hi", "there"]
irb(main):012:0> array << string.split("\t")
=> [["hi", "there"]]
irb(main):013:0> array += string.split("\t")
=> [["hi", "there"], "hi", "there"]

Ideas?

Also look up Array#join to make your life easier.
