Re^2: Split string using regex on \n or max line length (updated)

Update: The following modification to the regex eliminates the need for the s/\s+$// for @lines; above (works because \s includes newline):

I still plead for keeping the \W, best with non-greedifier i.e. \W?, so a final punctuation or hyphen is captured even though the limit is exceeded by one.

Hi flowdy, You're right that my second regex didn't operate like the OP's, but if you write `/(.{1,$len}\W?)/gm`, then that may split in the middle of a word, like your suggestion and unlike the OP's regex. I've updated my node. Thanks, -- Hauke D	[reply] [d/l]

Hi haukex, Yes, you are right. Then again, required `\W` will not match at the end of the line. So, `(?:\W\|$)` is closer to an ideal solution, which however is rather hypothetical until a proper set of positive and negative test cases is provided.	[reply] [d/l] [select]
