Remove all whitespaces in a string

ruby-talk

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

"bla@bla.de"

How can I achieve this?

Thanx

2

" bla @ bla.de ".gsub!(' ','')

You can use String.gsub [1]

irb(main):003:0> " bla @ bla. de ".gsub(/\s+/, '')
=> "bla@bla.de"

[1] http://dev.rubycentral.com/ref/ref_c_string.html#gsub

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

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

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
