NAME

       PPIx::EditorTools::FindVariableDeclaration - inds where a variable was declared using PPI

SYNOPSIS

	 # finds declaration of variable at cursor
	 my $declaration = PPIx::EditorTools::FindVariableDeclaration->new->find(
	   code =>
	     "package TestPackage;
use strict;
BEGIN {
	       $^W = 1;
       }
my $x=1;
$x++;"
	   line => 5,
	   column => 2,
	 );
	 my $location = $declaration->element->location;

DESCRIPTION

       Finds the location of a variable declaration.

METHODS

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

       find( ppi => PPI::Document $ppi, line => $line, column => $column ) =item find( code => Str $code, line => $line, column => $column )
	   Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to
	   process.  Searches for the variable declaration and returns a "PPIx::EditorTools::ReturnObject" with the declaration
	   ("PPI::Statement::Variable") available via the "element" accessor.

	   Croaks with a "no token" exception if no token is found at the location.  Croaks with a "no declaration" exception if unable to find
	   the declaration.

NAME

       PPIx::EditorTools::IntroduceTemporaryVariable - Introduces a temporary variable using PPI

SYNOPSIS

	   my $munged = PPIx::EditorTools::IntroduceTemporaryVariable->new->introduce(
	       code	      => "use strict; BEGIN {
	       $^W = 1;
       }
	my $x = ( 1 + 10 / 12 ) * 2;
	my $y = ( 3 + 10 / 12 ) * 2;
",
	       start_location => [ 2, 19 ],
	       end_location   => [ 2, 25 ],
	       varname	      => '$foo',
	   );
	   my $modified_code_as_string = $munged->code;
	   my $location_of_new_var_declaration = $munged->element->location;

DESCRIPTION

       Given a region of code within a statement, replaces all occurrences of that code with a temporary variable. Declares and initializes the
       temporary variable right above the statement that included the selected expression.

METHODS

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

       find( ppi => PPI::Document, start_location => Int, end_location => Int, varname => Str ) =item find( code => Str, start_location => Int,
       end_location => Int, varname => Str )
	   Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to
	   process.

	   Given the region of code specified by start_location and end_location, replaces that code with a temporary variable with the name given
	   in varname (defaults to "tmp"). Declares and initializes the temporary variable right above the statement that included the selected
	   expression.

	   Returns a "PPIx::EditorTools::ReturnObject" with the modified code as a string available via the "code" accessor (or as a
	   "PPI::Document" via the "ppi" accessor), and the "PPI::Token" where the new variable is declared available via the "element" accessor.

	   Croaks with a "no token" exception if no token is found at the location.  Croaks with a "no statement" exception if unable to find the
	   statement.
