How to truncate strings in Ruby?

[Marston A.]

So I'd think this is a very simple question, I've searched around the
manual and google but couldn't really find it.

So what is the method to truncate a string in Ruby? Similar to the
truncate(@text, 20) helper method in Rails? To get the first 20
characters of a string for example. Thanks in advanced

Slice it, just remember it's 0 indexed.
s = '0123456789'
s = s[0..4]
=> '01234'

@text[0...20]

@text[0, 20]

@text.slice(0, 20)

@text.slice!(0, 20) # modifies @text in place to become it's
"truncation"
