Question

I have a date string that I need to simplify in Ruby:

2008-10-09 20:30:40

I only want the day portion:

2008-10-09

I’m looking for a gsub line that will strip everything after a set number of characters or the first whitespace.

Answer 1

I prefer to use as simple a solution as I can. Using gsub is needlessly complex. Either of these will do it:

str = '2008-10-09 20:30:40'
str[/(\S+)/, 1] #=> "2008-10-09"
str[0, 10] #=> "2008-10-09"
