Answer 1

+5 A:

You can use ranges.

"string"[0..-4]

You beat me to it! You can also do this with slice: "string".slice(0..-4)

[ ] and slice are synonums

hi, thanks! I just found that I made a mistake on the second parameter of [ ] or slice; it is length rather than the ending position...

Careful! In Ruby 1.8, this *does not* remove the last characters, it removes the last *bytes*!

Jörg W Mittag 2010-06-17 10:59:07

Or `"string"[0...-3]`

+1 A:

You could use a regex with gsub ...

"string".gsub( /.{3}$/, '' )
