How to pass multiline String parameter?


username

Suppose I have this method:

def read_line_by_line(some_text)
  some_text.each |line| do (something) end
end

How can I do this? I have got:

my first line
of the input text

I tried to pass it as a parameter but got a weird output. It doesn't read line by line.

Here's what you want to try:

def read_line_by_line(some_text)
  some_text.each_line {|line| puts line }
end

str = <<-eot
my first line
of the input text
eot

read_line_by_line(str)
# >> my first line
# >> of the input text

See the documentation .String#each_line

renew

def read_line_by_line(some_text)
  some_text.each_line {|line| puts line }
end

str = "my first line\nof the input text"

read_line_by_line(str)
# >> my first line
# >> of the input text
