[ruby] How can I remove the string "\n" from within a Ruby string?

I have this string:

"some text\nandsomemore"

I need to remove the "\n" from it. I've tried

"some text\nandsomemore".gsub('\n','')

but it doesn't work. How do I do it? Thanks for reading.

If you want or don't mind having all the leading and trailing whitespace from your string removed you can use the strip method.

"    hello    ".strip   #=> "hello"   
"\tgoodbye\r\n".strip   #=> "goodbye"

as mentioned here.

edit The original title for this question was different. My answer is for the original question.

use chomp or strip functions from Ruby:

"abcd\n".chomp => "abcd"
"abcd\n".strip => "abcd"

Look here:

• How to replace multiple newlines in a row with one newline using Ruby

When you want to remove a string, rather than replace it you can use String#delete (or its mutator equivalent String#delete!), e.g.:

x = "foo\nfoo"
x.delete!("\n")

x now equals "foofoo"

In this specific case String#delete is more readable than gsub since you are not actually replacing the string with anything.

You don't need a regex for this. Use tr:

"some text\nandsomemore".tr("\n","")
