ppi::token::whitespace
PPI::Token::Whitespace(3) User Contributed Perl Documentation PPI::Token::Whitespace(3)NAME
PPI::Token::Whitespace - Tokens representing ordinary white space
INHERITANCE
PPI::Token::Whitespace
isa PPI::Token
isa PPI::Element
DESCRIPTION
As a full "round-trip" parser, PPI records every last byte in a file and ensure that it is included in the PPI::Document object.
This even includes whitespace. In fact, Perl documents are seen as "floating in a sea of whitespace", and thus any document will contain
vast quantities of "PPI::Token::Whitespace" objects.
For the most part, you shouldn't notice them. Or at least, you shouldn't have to notice them.
This means doing things like consistently using the "S for significant" series of PPI::Node and PPI::Element methods to do things.
If you want the nth child element, you should be using "schild" rather than "child", and likewise "snext_sibling", "sprevious_sibling", and
so on and so forth.
METHODS
Again, for the most part you should really not need to do anything very significant with whitespace.
But there are a couple of convenience methods provided, beyond those provided by the parent PPI::Token and PPI::Element classes.
null
Because PPI sees documents as sitting on a sort of substrate made of whitespace, there are a couple of corner cases that get particularly
nasty if they don't find whitespace in certain places.
Imagine walking down the beach to go into the ocean, and then quite unexpectedly falling off the side of the planet. Well it's somewhat
equivalent to that, including the whole screaming death bit.
The "null" method is a convenience provided to get some internals out of some of these corner cases.
Specifically it create a whitespace token that represents nothing, or at least the null string ''. It's a handy way to have some
"whitespace" right where you need it, without having to have any actual characters.
tidy
"tidy" is a convenience method for removing unneeded whitespace.
Specifically, it removes any whitespace from the end of a line.
Note that this doesn't include POD, where you may well need to keep certain types of whitespace. The entire POD chunk lives in its own
PPI::Token::Pod object.
SUPPORT
See the support section in the main module.
