Re^3: How do i extract 3 variables from each line in a file, and print them to a new file

That would print a comma at the end of the output string, so you would need a way to prevent it, let's say, like this:

for (@matches)
{
   print  "$_,";
}
print "\b ";

(Sorry about replacing foreach with for - someone mentioned to me earlier that it's faster and works the same way anyways)

Personally, I prefer Transient's way of doing things... although I don't quite understand why it parses split first and then map...

Re^4: How do i extract 3 variables from each line in a file, and print them to a new file by Transient (Hermit) on Jul 08, 2005 at 18:12 UTC
good question.. hope I'm not overstepping my bounds by responding..(and I hope I'm right!) `map { $_ =~ s/\D//g; $_ } split(':',(split(' ',$_))[-1]);` [download] is equivalent to `my @split_results = split(':',(split(' ',$_))[-1]); map { $_ =~ s/\D//g; $_ } @split_results;` [download] because map BLOCK LIST has to run the BLOCK for each LIST element (setting each LIST value to $_), it must know what is in that LIST. Hence, the execution of the split(s) before the execution of the BLOCK (and therefore the map).	[reply] [d/l] [select]

Oh, I see. I guess it's the space between map{} and split that threw me off as i'm not used to using map yet :) Thanks for nice explanation as well.

`for` is faster to type than `foreach`, and makes your program 3 bytes smaller, but apart from that, it has no effect. pbeckingham - typist, perishable vertebrate.	[reply] [d/l] [select]
