Re: split and join, what's the clever way to do it

It's already been specified that specifying split's 3rd argument is the solution.

I just wanted to note the 3rd argument is also very useful to disable split's default of removing trailing blank fields.

>perl -le"print join '|', split /\|/, '|a|b|c||'"
|a|b|c

>perl -le"print join '|', split /\|/, '|a|b|c||', -1"
|a|b|c||

I've always wondered why split is lossy by default, especially since I rarely if ever need the lossy behaviour. Either I don't care since I shouldn't be getting blank fields, or I want to keep the blank fields.

And there was me thinking that the 3rd argument would mean ignoring any extra pipes. Thanks for all the info guys! Lyle	[reply]
