Break text file into separate words and store in array in Ruby

I'm trying to read a text file and then store its individual words in an array. But I can't find a way to split it according to words.

text_file = []

File.open(file, "r") do |f|
  f.lines.each do |line|
    text_file << line.split.map(&:to_s)
  end
end

The above method creates an array of arrays which stores all the words in a single line in an array and so on.

Is there a way in which the array text_file can hold a single array of all the words?

Solution

  • Yes. Either do:

    text_file.push(*line.split.map(&:to_s))

    or:

    text_file.concat(line.split.map(&:to_s))
