PPIx::EditorTools::Lexer(3pm)				User Contributed Perl Documentation			     PPIx::EditorTools::Lexer(3pm)

NAME

       PPIx::EditorTools::Lexer - Simple Lexer used for syntax highlighting

SYNOPSIS

	 PPIx::EditorTools::Lexer->new->lexer(
	       code => "package TestPackage;
sub x { 1;
",
	       highlighter => sub {
		       my ( $css, $row, $rowchar, $len ) = @_;
		       ...
	       },
	     );

DESCRIPTION

       Go over the various interesting elements of a give piece of code or an already process PPI tree.  For each token call the user supplied
       'highlighter' function with the follow values:

	 $css	  - The keyword that can be used for colouring.
	 $row	  - The row number where the token starts
	 $rowchar - The character within that row where the token starts
	 $len	  - The length of the token

METHODS

       new()
	   Constructor. Generally shouldn't be called with any arguments.

       find( ppi => PPI::Document $ppi, highlighter => sub {...} ) =item find( code => Str $code, highlighter => sub ...{} )
	   Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to
	   process.  Return a reference to an array.

SEE ALSO

       This class inherits from "PPIx::EditorTools".  Also see App::EditorTools, Padre, and PPI.

PPIx::EditorTools::ReturnObject(3pm)			User Contributed Perl Documentation		      PPIx::EditorTools::ReturnObject(3pm)

NAME

       PPIx::EditorTools::ReturnObject - Simple object to return values from PPIx::EditorTools

SYNOPSIS

	 my $brace = PPIx::EditorTools::FindUnmatchedBrace->new->find(
	       code => "package TestPackage;
sub x { 1;
"
	     );
	 my $location = $brace->element->location;
	 my $ppi      = $brace->element->ppi;

DESCRIPTION

       Retuning a simple "PPI::Element" from many of the "PPIx::EditorTools" methods often results in the loss of the overall context for that
       element.  "PPIx::EditorTools::ReturnObject" provides an object that can be passed around which retains the overall context.

       For example, in "PPIx::EditorTools::FindUnmatchedBrace" if the unmatched brace were returned by its "PPI::Structure::Block" the containing
       "PPI::Document" is likely to go out of scope, thus the "location" method no longer returns a valid location (rather it returns undef).
       Using the "ReturnObject" preserves the "PPI::Document" and the containing context.

METHODS

       new()
	   Constructor which should be used by "PPIx::EditorTools". Accepts the following named parameters:

	   ppi A "PPI::Document" representing the (possibly modified) code.

	   code
	       A string representing the (possibly modified) code.

	   element
	       A "PPI::Element" or a subclass thereof representing the interesting element.

       ppi Accessor to retrieve the "PPI::Document". May create the "PPI::Document" from the $code string (lazily) if needed.

       code
	   Accessor to retrieve the string representation of the code. May be retrieved from the "PPI::Document" via the serialize method (lazily)
	   if needed.

SEE ALSO

       "PPIx::EditorTools", App::EditorTools, Padre, and PPI.
