1) This statement:

If you leave off the pattern, split assumes you want to split on /\s+/.

needs considerable qualification. You can't just 'leave off the pattern' except in one particular circumstance. Try this:

my $str = " foo bar baz "; my @spl = split $str; print "@spl";

It just doesn't work (at least in 5.6.1). You can only leave off the 'pattern' if you also leave off the 'target', ie if you are splitting on an implicit $_, eg:

while ( <DATA> ) { split; #do something interesting; }

2) This is plain wrong:

One special case is when you specify the string literal, " " (a quoted space), which does the same thing as specifying no delimiter at all (no argument).

There is nothing special about " " (see gmax's example above). You are confusing it with ' '.

3) One other minor point, I would suggest bringing the paragraph Preserving delimiters up to just below Where do delimiters go?, which IMHO would be a more logical ordering.



Update: See Abigail-II's post below

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
