Remove all whitespaces in a string

Ruby
1

I want to remove all whitespaces in a string.
I know strip to remove whitespaces at the beginning and the end
of the string.

example:

" bla @ bla. de "

should become

“[email protected]”

How can I achieve this?

Thanx

2

" bla @ bla.de ".gsub!(’ ‘,’')

3

gsub( ’ ', ‘’)

You can use String.gsub [1]

irb(main):003:0> " bla @ bla. de ".gsub(/\s+/, ‘’)
=> “[email protected]”

Sorry, I meant

your_string.gsub(’ ', ‘’)

" bla @ bla. de   ".delete(" ")
it maybe a good idea for you to read the PickAxe

Mmmh…I already used this syntax…then there must be a
problem with my RoR code…

I will use the according ML.

Thanx.

Hi,

since Strings are Enumerable I created a singleton method that
overwrites the default one:

def str.each &block
self.split( // ).each &block
end
str.reject { |char| char =~ /\s/ }

But I don’t know if this is going to brake anything…

Sincerely
Florian

This is probably slower, but here is another way you can try.

p " bla @ bla. de ".split(/\s+/).join
