PPI::Token::Comment - A comment in Perl source code
PPI::Token::Comment 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 :( bar /w;
In PPI, comments are represented by
These come in two flavours, line comment and inline comments.
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
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
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.
line accessor returns true if the
PPI::Token::Comment is a line comment, or false if it is an inline comment.
