CentOS 7.0 - man page for ppi::token::comment (centos section 3)

PPI::Token::Comment(3)	       User Contributed Perl Documentation	   PPI::Token::Comment(3)

       PPI::Token::Comment - A comment in Perl source code

	 isa PPI::Token
	     isa PPI::Element

	 # This is a PPI::Token::Comment

	 print "Hello World!"; # So it this

	 $string =~ s/ foo  # This, unfortunately, is not :(

       In PPI, comments are represented by "PPI::Token::Comment" objects.

       These come in two flavours, line comment and inline comments.

       A "line comment" is a comment that stands on its own line. These comments hold their own
       newline and whitespace (both leading and trailing) as part of the one
       "PPI::Token::Comment" object.

       An inline comment is a comment that appears after some code, and continues to the end of
       the line. This does not include whitespace, and the terminating newlines is considered a
       separate PPI::Token::Whitespace token.

       This is largely a convenience, simplifying a lot of normal code relating to the common
       things people do with comments.

       Most commonly, it means when you "prune" or "delete" a comment, a line comment disappears
       taking the entire line with it, and an inline comment is removed from the inside of the
       line, allowing the newline to drop back onto the end of the code, as you would expect.

       It also means you can move comments around in blocks much more easily.

       For now, this is a suitably handy way to do things. However, I do reserve the right to
       change my mind on this one if it gets dangerously anachronistic somewhere down the line.

       Only very limited methods are available, beyond those provided by our parent PPI::Token
       and PPI::Element classes.

       The "line" accessor returns true if the "PPI::Token::Comment" is a line comment, or false
       if it is an inline comment.

       See the support section in the main module.
