NAME

Perl::Critic::Utils::PPI - Utility functions for dealing with PPI objects.

DESCRIPTION

Provides classification of PPI::Elements.

INTERFACE SUPPORT

This is considered to be a public module. Any changes to its interface will go through a deprecation cycle.

IMPORTABLE SUBS

"is_ppi_expression_or_generic_statement( $element )"

Answers whether the parameter is an expression or an undifferentiated statement. I.e. the parameter either is a PPI::Statement::Expression or the class of the parameter is PPI::Statement and not one of its subclasses other than "Expression".

"is_ppi_generic_statement( $element )"

Answers whether the parameter is an undifferentiated statement, i.e. the parameter is a PPI::Statement but not one of its subclasses.

"is_ppi_statement_subclass( $element )"

Answers whether the parameter is a specialized statement, i.e. the parameter is a PPI::Statement but the class of the parameter is not PPI::Statement.

"is_subroutine_declaration( $element )"

Is the parameter a subroutine declaration, named or not?

"is_in_subroutine( $element )"

Is the parameter a subroutine or inside one?

"get_constant_name_element_from_declaring_statement($statement)"

Given a PPI::Statement, if the statement is a "use constant" or Readonly declaration statement, return the name of the thing being defined.

Given

     use constant 1.16 FOO => 'bar';
 
 

this will return ``FOO''. Similarly, given

     Readonly::Hash my %FOO => ( bar => 'baz' );
 
 

this will return ``%FOO''.
