PPIx::EditorTools::IntroduceTemporaryVariable(3pm) User Contributed Perl Documentation PPIx::EditorTools::IntroduceTemporaryVariable(3pm)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.
SEE ALSO
This class inherits from "PPIx::EditorTools". Also see App::EditorTools, Padre, and PPI.
