HiIs there a more direct way than this to get ‘grep -v’?
c=%w{a b c} #=> [“a”, “b”, “c”]
c -= c.grep(/a/) #=> [“b”, “c”]I would much rather do:
c.grep!(/a/v)
or
c.grep!(/a/,‘v’)
Or even:
c.delete(‘a’)

Doesn’t work for ‘a’ being more than one character.
How does one do a negative regex match?

Paranoids are people, too; they have their own problems. It’s easy to
criticize, but if everybody hated you, you’d be paranoid too.

Well, there’s Enumerable#reject – but it takes a
block. Might be nice if there were a regex version
also. But that opens the proverbial can of worms.

How about c.reject {|e| e =~ /a/} ?
(or c.delete_if if you want to modify c)

Try http://member.nifty.ne.jp/nokada/archive/reop.rb.
require ‘reop’
c.grep(-/a/)
