Hi there,
i have a little problem. I want to read out lines of a file. But every time
ruby reads it out, there is always this \n at the end of the line. Does
anybody know how to get rid of this character?
Example:
f=File.open(“123”)
f.readlines[0]
for example returns the first line: 12345\n
If you don’t know what I mean, feel free to write me. I don’t know how to
express it correctly…
Thanks
if I understand what you want, maybe this could help you:
f.readlines[0].chomp!

You might also find it a useful habit to pair any readlines call with a
chomp mapped across the entire array.
contents = IO.readlines(filename).map {|line| line.chomp}
also note - when using readlines as a class method, there’s no need to
open and close the file.
