Re: [BrightNail] A challenge: Email Extractor from all directories to text file???

Hey BrightNail,

First of all there are people like mhx who solve the same problem in 10 times less lines Wink and I don't understand all of it either Blush. The only thing I can say in my defense is that I prefer to write all the code by myself - this way you learn more (of course leaving more place to an error).

Regarding the ($$;$) - perlguru is a fine the place to ask questions ;-)

By declaring sub with parentheses you may decide how many parameters the sub will accept. Anything after the semicolon is optional. ($$;$) means that the sub accepts 2 or 3 scalar variables. Say, (%;$$$) declares sub that accepts a hash and, optionally, up to 3 scalars as its parameters.

Oh, sorry - now I understand - if you're talking about the first sub ScanDir($$;$); it's not a call - it's a sub predeclaration. The ScanDir is a recursive sub, i.e. it calls itself for every subdirectory found, so you have to predeclare it - just make sure the line is identical to the original sub declaration...

Hope this helps, pal SmileSmileSmile
