Hello,
Given the string 'abcdefghijklmnopq', I wish to add a line break
every 5 characters:
abcde
fghij
klmno
pq
Method 1 below works, but my split() in method 2 captures 'something
unexpected' at each match. Could someone please tell me what is split
capturing that I am not seeing?

Because of the capturing (), split also returns the separators.
See perldoc -f split.
Suggestion:
my @bar2 = split( /./, $foo );

The comments made by Dr. Ruud and John W. Krahn are correct.

Aaargh, I was suddenly mixing up split /()/ and /()/g. I really

Thank you all for the clarifications regarding split(). I should pay
more attention when I read the documentation (or get more sleep).

I have this script that reads in lines from a configuration file, processes
them, and then stores them in a hash. Everything is working (mostly) but I
really don't like the snippet below and wanted to see if anyone could
suggest a better solution. I would call better a syntactically shorter,

If your pattern always looks like this then try:
#!/usr/bin/perl
use strict;#make me behave
my $name; #holds the key part of config
my $value; #the value of par
Hi,
I'm not sure that I got it right, but let's try:
considering you want to parse several substrings from the line, each of them
can be either bareword (== sequence of non-whitespace characters) or a quoted
strings:
my $line = 'whatever "this" \'line is\'';
$line =~ s/\s*$//;
my @parts;

Randal, would you mind if I used this as an example of \G and /gc in my
regex book? Due credit would be given, of course.
