Q&A  > regular expressions


Description:

If someone enters something that SHOULD be in the hash, but isn't, how could I use a regexp to test to see what values closely match it and return those values. (the values will only be matched against the keys)

Match against the keys of the hash.

But you might be in luck: CPAN has Tie::Hash::Approx and Tie::Hash::Regex, one of which might be suitable for you.

grep {/$regex/} keys %hash

    [1nickt]: Corion HPs? ugh. I was impressed with Lenovo's gaming laptops; if it weren't for the red backlighting and general flashiness of the aesthetic, I might have gone with that. But all that was until I discovered that the Dell Precision line is still around.
    [1nickt]: stevieb I don;t doubt that there's a difference. BestBuy has "consumer" models only on display.
    [ambrus]: 1nickt: for some reason, these days they call every computer "gaming", even ones that gamers wouldn't buy. I've bought a keyboard that was labelled "gamer", despite that it has hard springs and seems to be way better for typing than for gaming;
    [1nickt]: I though the gamers like that because they bash the keys so hard.
    [ambrus]: and I've seen motherboards with no fast expansion ports for a video card but built-in hardware RAID advertized as "gaming".
    LanX has a shaming laptop
    [ambrus]: 1nickt: my impression is that the gamers like the softer springs, because fast reaction time is more important to them then feedback from keypresses to recognize typos.
    [1nickt]: Ah, I see. I did read some gamer mag reviews, and yes, they lamented the fact that laptops with no discrete video card are sold as "gaming" hardware.
    [1nickt]: But, they do have red keyboard backlighting! And gargoyles on the front, or words like "Maxxx" here and there. They know their demographic!
    [1nickt]: True gamers don;t buy Dells, HPs, or Lenovos, I think ;-)
