SYNOPSIS

10           my $munged = PPIx::EditorTools::IntroduceTemporaryVariable->new->introduce(
11               code           => "use strict; BEGIN {
12               $^W = 1;
13       }\n\tmy $x = ( 1 + 10 / 12 ) * 2;\n\tmy $y = ( 3 + 10 / 12 ) * 2;\n",
14               start_location => [ 2, 19 ],
15               end_location   => [ 2, 25 ],
16               varname        => '$foo',
17           );
18           my $modified_code_as_string = $munged->code;
19           my $location_of_new_var_declaration = $munged->element->location;

DESCRIPTION

22       Given a region of code within a statement, replaces all occurrences of
23       that code with a temporary variable. Declares and initializes the
24       temporary variable right above the statement that included the selected
25       expression.
26

METHODS

28       new()
29           Constructor. Generally shouldn't be called with any arguments.
30
31       find( ppi => PPI::Document, start_location => Int, end_location => Int,
32       varname => Str ) =item find( code => Str, start_location => Int,
33       end_location => Int, varname => Str )
34           Accepts either a "PPI::Document" to process or a string containing
35           the code (which will be converted into a "PPI::Document") to
36           process.
37
38           Given the region of code specified by start_location and
39           end_location, replaces that code with a temporary variable with the
40           name given in varname (defaults to "tmp"). Declares and initializes
41           the temporary variable right above the statement that included the
42           selected expression.
43
44           Returns a "PPIx::EditorTools::ReturnObject" with the modified code
45           as a string available via the "code" accessor (or as a
46           "PPI::Document" via the "ppi" accessor), and the "PPI::Token" where
47           the new variable is declared available via the "element" accessor.
48
49           Croaks with a "no token" exception if no token is found at the
50           location.  Croaks with a "no statement" exception if unable to find
51           the statement.
