Well, specifically for the apostrophe, \b{wb} doesn't seem to take initial ones as part of words. It breaks your sample sentence as follows: {Not} {_} {sure} {_'} {cause} {_} {that's} {_'} {bout} {_} {words} {_} {also} {_} {including}

But I agree with you that there are probably other cases of words (as defined by \b{wb}) that don't start by a character matching \w.

At the end, my conclusion is that the only way to handle the OP problem in a way fully consistent with \w{wb} semantics is to just split using it, and maybe repack non word fragments afterwards:

my $book = "Not sure 'cause that's 'bout words also including ...\n.\n +_\n\n..."; my @fragments; my $last_was_symbol; for (split /\b{wb}/, $book) { if (/[\w\n]/) { $last_was_symbol = 0; push @fragments, $_; } else { if ($last_was_symbol) { $fragments[-1] .= $_; } else { push @fragments, $_; $last_was_symbol = 1; } } } sub show { my $str = shift; $str =~ tr/\n/$/; $str =~ tr/ /_/; print "{$str} "; } show $_ for @fragments; print "\n";

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
