Regular Expression help - Replacing Regexp that worked with Oniguruma in 1.8.6

Ruby

Hi

On our way to shifting to Ruby 1.8.7 - away from the beloved
Oniguruma-Patch - I am tripping over our usefull regular expression used
in Ruby 1.8.6 - so if anybody is strong in refactoring regular
expressions, please let me know.

sample one:

http://choddb.rubyforge.org/ODDB/SwissmedicPlugin.html

%r{excipiens\s+(ad|pro)\s+(?((?!\bpro\b)[^.])+)}u

and

%r{pro\s+(?(?[\d.,]+)\s*(?[kcmuµn]?[glh]))}u

And this one on line 148

http://url.ba/kxez

All three samples need to work in Ruby 1.8.7 and in 1.9.2.

They currently work perfectly fine in Ruby 1.8.6 with the beloved
Oniguruma-Patch V2.5.9

Any hints or Feedback is welcome.

Can you give hints about what exactly you are asking? Do you have
syntax errors, do the expressions not match? What is the reason for
your posting?

Ideally you would provide sample code and text to match.

Cheers

Basically our software does not start-up with Ruby 1.8.7 and with Ruby
1.9.2 as Oniguruma is missing.

Ideally you would provide sample code and text to match.

Ok, I will try to produce these beyond what I already supplied above.

Could you provide some samples of inputs and what you expect/are getting
out
of the expressions. Rather difficult to ensure one can be of assistance
without knowing the specific targets…

He’s just taking another opportunity to complain that a patch that he
privately applied to 1.8.6 wasn’t applied to 1.8.7 or 1.9. Instead of
either sticking to what he likes or migrating his code (in this case
named groups–really not hard if he’d just think about it), he’s
complaining. Again. Ad nauseum. Just like he did on ruby-core@.

Since when is Oniguruma missing from 1.9.2???

09:14:24 ~$ for e in ruby ruby19; do $e -v; $e -ce ‘/(?)/’; done
ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-cygwin]
-e:1: undefined (?..) sequence: /(?)/
ruby 1.9.2p136 (2010-12-25 revision 30365) [i386-cygwin]
Syntax OK
09:14:33 ~$

If you migrate away from 1.8.6 then why do you switch to 1.8.7 and not
1.9.* which is significantly faster and has Oniguruma?

Ideally you would provide sample code and text to match.

Yes, I think you should do that.

Kind regards
