text2array.rb

This Ruby code snippet demonstrates how to convert a string into an array of lines in Ruby. The <<~TEXT syntax is used to indicate that the following indented block should be treated as a here document, and the text variable is assigned to the indented text block.

The first line of the code defines a variable called lines, which is set to the result of calling the lines method on the string text. The lines method returns an array of lines in the string, each of which is represented as a separate element in the array. The &:chomp symbol is used to indicate that the chomp method should be called on each line before it is added to the array.

The resulting array lines contains three elements, each representing one line of the original text string.

Ruby code snippet

text = <<~TEXT
  a
  b
  c
TEXT
#=> "a\nb\nc\n"

lines = text.lines.map(&:chomp)
#=> ["a", "b", "c"]
