NAME

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

SYNOPSIS

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