( #3333=superdoc: print w/replies, xml ) Need Help??
Woops, it also converts (11,2,3) to "11-3" and (1,2,30) to "1-30". :)

Here's one way to fix it:

sub num2range { local $_ = join ',' => @_; s/(?<!\d)(\d+)(?:,((??{$++1}))(?!\d))+/$1-$+/g; return $_; }
The negative look-behind at the beginning and the negative look-ahead near the end prevent the regex from matching only part of a number, like the second 1 in 11 or the 3 in 30.

    [marto]: Corion, some not too serious issues with the kids, hopefully, other than that just dealing with commuting by car again in the winter, not much fun so far, and there's no real 'bad' weather yet :)
    [marto]: 1nickt, glad to hear it, I'm sure you'll bring improvements to their stack in due course ;)
    [1nickt]: Just trying to adjust to a new culture. Better doc than I am used to , but quite a bit more Agiley meta-bullshit; at least half a dozen meetings a week, strict "sprint" schedule etc. I'll adjust. And I hope to just switch off after the "scrum" each day at
    [1nickt]: ... the end of the afternoon. marto How are you, snowed in? Mum and Dad expecting snow today in Surrey. (Have 5" on the ground here in NJ. And my son's high school in SOCal closed until after Xmas due to fires.)
    [Corion]: 1nickt: In a sense the meta-bullshit might even be beneficial to you as you get to hear the cow-orkers talk (or not talk) about the issues you perceive. I think Agile is mostly about the meta ;)
    [Corion]: 1nickt: On Sunday maybe 10cm of snow fell, and the airport closed, and the trains stopped running etc :) It always comes as a surprise that snow falls here during the winter...
    [marto]: 1nickt, no snow, just some ice on the roads and the usual idiocy associated with humans and driving in less than ideal conditions
