Working on a first plain Ruby script, need help with `join'

[Jesse Crockett]

I need help in the block to create a csv file of these entries.

the file, abridged:

@verb_index = "

aah v 1 1 @ 1 0 00865776
abacinate v 1 1 @ 1 0 02168378
abandon v 5 4 @ ~ $ + 5 5 02228031 02227741 02076676 00613393 00614057
abase v 1 3 @ ~ + 1 0 01799794
abash v 1 3 @ ~ + 1 0 01792097

n.split
n.join(", ") # fails

Do you want to do n.split.join(", ") ?

 

[Martin DeMello]

n.split
n.join(", ") # fails

n.split returns a new object containing the array of split entries
from n. you aren't assigning this new object to anything, so it is
silently discarded. the object pointed to by n is unchanged. what you
want is something like

a = n.split
a.join(", ")

or more compactly

n.split.join(", ')

Yes. How do I put them into a CSV file? Thank you.

Use FasterCSV (which replaces CSV in the standard lib for Ruby 1.9)

Supposing you're reading from stdin or from files passed as argument and
you're writing to stdout:

ARGF.each { |line| puts line.split.join(', ') }

If you want to output to file

output_file = open ('output.cvs', 'w')
ARGF.each { |line| output_file.puts line.split.join(', ') }
