in reply to Re^7: using hashes
in thread iterating hash keys?

Imagine these values:

banana => 25

bana => 20

bana-na => 15

na => 10

For the translation to, let's say:

bana-na,banana

Currently the output is:

20-10,25

That's what made me thought the hyphens were a special case...

    No, but they are being marked as word boundaries, and so they pass the regex I gave before. For the situation you've described, the only obvious solution I can see is to traverse the key list from long to short as I've shown in Re^5: using hashes. Things get messy with replacement lists when your keys are not independent.

      I see... Thanks again!
