Hi.

I have a series of strings. I would like to compare them and determine a "match" string automagically.

For example:

  Error 123 on SystemA file not found error
  Error 123 on SystemB file not found error
  Error 123 on SystemC file not found error

I would like to determine the differences (splitting on stopwords such as space, colon, etc) and get a pattern which matches such as:

  Error 123 on $1 file not found error

[download]

I plan on running several strings through something such as Levenshtein to determine how close they are. If they are close enough, I'll try to get a pattern. If they are significantly different, obviously I won't even try.

Another example to show multiple variables:

  Error 124 on User1:FileA no space left
  Error 124 on User2:FileB no space left
  Error 124 on User3:FileC no space left
 
  Error 124 on $1:$2 no space left

Does such a beastie already exist in CPAN? I have been unsuccessful in finding one.

Thanks
