Remove multiple spaces and new lines inside of String

Suppose we have string like this:

Hello, my\n       name is Michael.

How can I remove that new line and strip those spaces after that into one inside of string to get this?

Hello, my name is Michael.

You can add just the squish method (and nothing else) to Ruby by including just this Ruby Facet:

https://github.com/rubyworks/facets/blob/master/lib/core/facets/string/squish.rb

require 'facets/string/squish'

Then use

"my    \n   string".squish #=> "my string"

Doesn't require Rails.

Use squish
currency = " XCD"
str = currency.squish
 str = "XCD" #=> "XCD"

Try This:

s = "Hello, my\n       name is Michael."
s.gsub(/\n\s+/, " ")

To illustrate Rubys built in squeeze:

this regex will replace instance of 1 or more white spaces with 1 white space, p.s \s will replace all white space characters which includes \s\t\r\n\f:

a_string.gsub!(/\s+/, ' ')

Similarly for only carriage return

str.gsub!(/\n/, " ")

First replace all \n with white space, then use the remove multiple white space regex.

my_string = "Hello, my\n       name is Michael."
my_string = my_string.gsub( /\s+/, " " )

Use String#gsub:

s = "Hello, my\n       name is Michael."
s.gsub(/\s+/, " ")

The simplest way would probably be

s = "Hello, my\n       name is Michael."
s.split.join(' ') #=> "Hello, my name is Michael."
