Issue #11735 has been updated by David Rodr=C3=ADguez.


I don't think the two features are the same, and would find both of them us=
eful.

Hi,

I have been using this `String#squish` method so many time when I'm using R=
ails, and I think it should be a useful addition to core.

Here's the method on Rails' documentation: http://api.rubyonrails.org/v4.2.=
5/classes/String.html#method-i-squish

This method is very useful when you have to write a multi-line string using=
 heredoc, but you actually does not care about the white-spaces before, aft=
er, and in-between the string.

For example:

~~~ruby
<<-SQL.squish
  SELECT *
  FROM users
  WHERE users.username =3D 'sikachu'
SQL
#=3D> "SELECT * FROM users WHERE users.username=3D'sikachu'"
~~~

Another example usage is when you are on the project that have a line lengt=
h code standard, and you have to write a long warning message that needs to=
 be printed to stdout:

~~~ruby
puts <<-WARNING.squish
  Unable to connect to the server. Please double-check that you are current=
ly
  connecting to the internet and your proxy server is working.
WARNING
#=3D> Unable to connect to the server. Please double-check that you are cur=
rently connecting to the internet and your proxy server is working.
~~~

By the way, this is my first patch and my first time writing something in C=
, so there might be something that does not look right to you. I'll happy t=
o revise this patch (and learn about C in the process!) from your feedback.

Thank you,
Prem
