Using String's Strip Method Rather Than Chomp
I have been in the habit of using
String#chomp when interactively
requesting input from people. I am considering using
instead. It does more than
chomp, in that it will remove leading
whitespace, trailing whitespace and still the
$/ which is to say the
record separator. I think that it is more suitable for interactive
input, unless you are counting on leading whitespace from someone for
The statement that we always say when talking about
to_f is that
to_f does the same thing as
chomp, and this is
almost true. But
to_f actually work more like strip.

As you can see, in reality
to_i strips the leading whitespace, and by
definition any trailing whitespace (though in reality all string content
that isn’t part of the first recognizable ‘numeric-like’ string)
including the record separator.
So, I am trading in my habitual
String#chomp use for the cleaner
String#strip use, and where appropriate
String#strip! and I believe I
will still have fun with Ruby!
Let me know what you think about this small movement?
