13 This is a bit of a grab bag, but works as far as it goes.
14
16 Element Functions
17 "$pkgelem = Perl::Critic::Pulp::Utils::elem_package ($elem)"
18 $elem is a "PPI::Element". Return the "PPI::Statement::Package"
19 containing $elem, or "undef" if $elem is not in the scope of any
20 package statement.
21
22 The search upwards begins with the element preceding $elem, so if
23 $elem itself is a "PPI::Statement::Package" then that's not the one
24 returned, instead its containing package.
25
26 "$bool = Perl::Critic::Pulp::Utils::elem_in_BEGIN ($elem)"
27 Return true if $elem (a "PPI::Element") is within a "BEGIN" block
28 (ie. a "PPI::Statement::Scheduled" of type "BEGIN").
29
30 "$bool = Perl::Critic::Pulp::Utils::elem_is_comma_operator ($elem)"
31 Return true if $elem (a "PPI::Element") is a comma operator
32 ("PPI::Token::Operator"), either "," or "=>'.
33
34 Policy Parameter Functions
35 "Perl::Critic::Pulp::Utils::parameter_parse_version ($self, $parameter,
36 $str)"
37 This is designed for use as the "parser" field of a policy's
38 "supported_parameters" entry for a parameter which is a version
39 number.
40
41 { name => 'above_version',
42 description => 'Check only above this version of Perl.',
43 behavior => 'string',
44 parser => \&Perl::Critic::Pulp::Utils::parameter_parse_version,
45 }
46
47 $str is parsed with the "version.pm" module. If valid then the
48 parameter is set with "$self->__set_parameter_value" to the
49 resulting "version" object (so for example field
50 $self->{'_above_version'}). If invalid then an exception is thrown
51 per "$self->throw_parameter_value_exception".
52
54 Nothing is exported by default, but the functions can be requested in
55 usual "Exporter" style,
56
57 use Perl::Critic::Pulp::Utils 'elem_in_BEGIN';
58 if (elem_in_BEGIN($elem)) {
59 # ...
60 }
61
62 There's no ":all" tag since this module is meant as a grab-bag of
63 functions and importing as-yet unknown things would be asking for name
64 clashes.
