Ruby : Trim New blank lines

Question

Hi All,

Please help me to solve this.

This is my string

str = "aaa\n\n\nbbb\n\nccc\ddd\n" means four blank lines, all together eight lines

I want to return this in one line

Output should be like this (aaabbbcccddd) in single line

I used various trim functions to get the output but still i am failing to do it. if Anyone know the possible way, please help on this.

Thanks -Samitha

Answer 1

str.gsub(/\n/,'')

Answer 2

> str = "aaa\n\n\nbbb\n\nccc\ddd\n" 
=> "aaa\n\n\nbbb\n\ncccddd\n"
> str.gsub("\n", "")
=> "aaabbbcccddd"

Answer 3

The Ruby (and slightly less Perl-ish) way:

new_str = str.delete "\n"

...or if you want to do it in-place:

str.delete! "\n"

Answer 4

What about :

str.chop
and
str.chop!
