Oniguruma

Ruby
1

My understanding is that Oniguruma is standard in 1.9 and
can be built into 1.8.x – correct?

So my first two questions are:

  1. How to do a simple test that confirms whether or not
    Oniguruma is there?

  2. How to build the stable snapshot with Oniguruma?

Thanks,
Hal

From what I can gather, the regular (‘old’) way doesn’t support
Lookbehind, but Oniguruma does, so:

[rosco@jukebox dev]$ irb
irb(main):001:0> "ab" =~ /(?<!a)b/
SyntaxError: compile error
(irb):1: undefined (?...) sequence: /(?<!a)b/
     from (irb):1
  irb(main):002:0> quit

[rosco@jukebox dev]$ irb9
irb(main):001:0> "ab" =~ /(?<!a)b/
=> nil
irb(main):002:0> "db" =~ /(?<!a)b/
=> 1

would appear to do it.

Umm, don’t know.

Cheers,

I had to apply one hunk of the patch by hand, but otherwise it was
straightforward.

Googling around, the only information I found on Oniguruma
was in Japanese. Is there an overview in English?
