Re^3: Better Way of Manipulating Array Elements

You are missing that he want's a blanks after the commas. And I improve (golfwise) to:

perl -pe's/(d)/new($1)/; s/\n/, / unless eof'

But since capturing a literal regex is silly anyway, the best I can think of at the moment is

perl -pe's/d/new(d)/;s/\n/, / unless eof'
[download]

You are missing that he want's a blanks after the commas. That's not what he said ("join all the elements by a comma"), and that's not what he's currently doing (`print join ",", @z;`). Trivial change either way. I improve (golfwise) to [...] `unless eof` Good, but `if !eof` is even shorter (6 from 10) and clearer. `if !eof()` means something different and might be desirable. But since capturing a literal regex is silly I doubt the OP is really matching "d".	[reply] [d/l] [select]

print join ", ", map { chomp; s/(d)/new(\1)/ } @a; I was just looking at that - but you are right about the blanks - 1:0 for you. if !eof is shorter and clearer. Damn it you are right again - 2:0 for you. defeated :-) if !eof() means something different and might be desirable My previous post was not really meant to be taken seriously - so it's even better that I learn something here - many thanks!
