Re: Why does split on /./ not split the string?

split returns only the string segments between, but not including the matching chars. For example:

my @list = split(/;/, 'one;two;three');
# @list is now ('one', 'two', 'three');

Since /./ matches on any char, what you end up with is essentially emptiness. The lookahead works because it is looking ahead, not "matching" in the same sense as /./. FYI: split(q//, $string); will split the string into chars, and is a little easier to understand (and possibly faster) than using /(?=.)/.

`split` returns only the string segments between, but not including the matching chars. <nit> Uhm, then what does this do? `my @list = split /([\W]+)/, 'one;two--three!!!';` [download] Updated: Corrected '+' typo. </nit> -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l] [select]

Your pattern to split has capturing parentheses, which returns fields along w/ the delimiters; see `perldoc -f split`. Also, that `[+]` (mind you `+` here is just a plain plus sign) is useless as the string to be split lacks one. Try this ... Read more... (631 Bytes)	[reply] [d/l] [select]

I was trying to nitpick, but failed somewhat. The point is that `split`'s behavior (wrt/ the OP) depends on the presence of capturing parens and the DWIMmery of `split`. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l] [select]
