I need to, from a .txt file that has multiple tweets (one on each line), read this file and put it in a variable in the following format:
[1, "texto da primeira linha do arquivo"], [1, "texto da segunda linha"]
I was able to read the file and print it, but I can not mount the arrays vector.
You can use the method readlines
tweets = IO.readlines('filename.txt')
puts tweets[0] # => "primeiro tweet"
But if you want an array identical to what you requested, do so:
tweets = IO.readlines('filename.txt').each_with_index.map do |line, line_num|
[line_num, line]
end
puts tweets[0] # => [0, "primeiro tweet"]
