Hi,

The normal behavior 'abc' howManyMatch: 'abd' --> 2.

I got suprized the way Blanks and new lines are handled.

'\**' withCRs howManyMatch: '\\**' withCRs. --> 2 instead of 1

'ab\ **' withCRs howManyMatch: 'ab\\**' withCRs. --> 4 instead of 3

'\ **' withCRs howManyMatch: '\\**' withCRs. --> 3 instead of 1

'ab\ **' withCRs howManyMatch: 'ab\\**' withCRs. --> 5 instead of 3

The behavior is the same in both Pharo 3 and Pharo 4.

Reading the code of does not help me understand why it's this way

String>>howManyMatch: string "Count the number of characters that match up in self and aString." | count shorterLength |

count := 0. shorterLength := self size min: string size. 1 to: shorterLength do: [:index | (self at: index) = (string at: index ) ifTrue: [ count := count + 1 ]]. ^ count

Noury, I think you're looking after the number of common chars only at beginning. Wouldn't the method finder hit a better match? The method works as advertised in the comment. Though I find it very questionnable: Doesn't "match" imply some other semantic like pattern matching (and thus things like wild character etc...)? Is such specific behavior usefull? Really? Why/Where?
