PPI::Token::Comment(3) User Contributed Perl Documentation PPI::Token::Comment(3)
PPI::Token::Comment - A comment in Perl source code
# 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
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.
