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.
