How to parse a tab-separated line of text in Ruby?
14,731
I'm not sure I quite understand your question, but if you want to split the lines on tab characters, you can specify that as an argument to split:
line.split("\t").each ...
or you can specify it as a regular expression:
line.split(/\t/).each ...
Each basically just iterates through all the items in an array, and split produces an array from a string.

I find Ruby's
each
function a bit confusing. If I have a line of text, aneach
loop will give me every space-delimited word rather than each individual character.So what's the best way of retrieving sections of the string which are delimited by a tab character. At the moment I have:
line.split.each do |word| ... end
but that is not quite correct.
