Ruby function to remove all white spaces? - microdistillation983799 - 07-18-2023
What is the Ruby function to remove **all** white spaces? I'm looking for something kind of like PHP's `trim()`?

Also don't forget:
$ s = " I have white space ".split
=> ["I", "have", "white", "space"]

If you want to remove only leading and trailing whitespace (like PHP's trim) you can use `.strip`, but if you want to remove ***all*** whitespace, you can use `.gsub(/\s+/, "")` instead .

It's a bit late, but anyone else googling this page might be interested in this version -
If you want to clean up a chunk of pre-formatted text that a user may have cut & pasted into your app somehow, but preserve the word spacing, try this:
content = " a big nasty chunk of something
that's been pasted from a webpage or something and looks
like this
"
content.gsub(/\s+/, " ").strip
#=> "a big nasty chunk of something that's been pasted from a webpage or something and looks like this"

Related answer:
" clean up my edges ".strip
returns
"clean up my edges"

s = "I have white space".delete(' ')
And to emulate PHP's `trim()` function:
s = " I have leading and trailing white space ".strip

"asd sda sda sd".gsub(' ', '')
=> "asdsdasdasd"

" Raheem Shaik ".strip
It will removes left & right side spaces.
This code would give us: `"Raheem Shaik"`

"1232 23 2 23 232 232".delete(' ')
=> "123223223232232"
Delete works faster =)

Ruby's `.strip` method performs the PHP equivalent to `trim()`.
To remove all whitespace:
" leading trailing ".squeeze(' ').strip
=> "leading trailing"
@Tass made me aware that my original answer removes duplicate letters in succession - YUCK! I've since switched to the squish method which is smarter about such occurrences if using the Rails framework.
require 'active_support/all'
" leading trailing ".squish
=> "leading trailing"
" good men ".squish
=> "good men"
