NAME

6       Perl::Critic::Theme - Construct thematic sets of policies.
7

DESCRIPTION

9       This is a helper class for evaluating theme expressions into sets of
10       Policy objects.  There are no user-serviceable parts here.
11

INTERFACE SUPPORT

13       This is considered to be a non-public class.  Its interface is subject
14       to change without notice.

METHODS

17       "new( -rule => $rule_expression )"
18           Returns a reference to a new Perl::Critic::Theme object.  "-rule"
19           is a string expression that evaluates to true or false for each
20           Policy..  See "THEME RULES" for more information.
21
22       "policy_is_thematic( -policy => $policy )"
23           Given a reference to a Perl::Critic::Policy object, this method
24           returns evaluates the rule against the themes that are associated
25           with the Policy.  Returns 1 if the Policy satisfies the rule, 0
26           otherwise.
27
28        rule()
29           Returns the rule expression that was used to construct this Theme.
30           The rule may have been translated into a normalized expression.
31           See "THEME RULES" for more information.
32
33   THEME RULES
34       A theme rule is a simple boolean expression, where the operands are the
35       names of any of the themes associated with the Perl::Critic::Polices.
36
37       Theme names can be combined with logical operators to form arbitrarily
38       complex expressions.  Precedence is the same as normal mathematics, but
39       you can use parentheses to enforce precedence as well.  Supported
40       operators are:
41
42          Operator    Altertative    Example
43          ----------------------------------------------------------------
44          &&          and            'pbp && core'
45          ||          or             'pbp || (bugs && security)'
46          !           not            'pbp && ! (portability || complexity)
47
48       See "CONFIGURATION" in Perl::Critic for more information about
49       customizing the themes for each Policy.

SUBROUTINES

52       cook_rule( $rule )
53           Standardize a rule into almost executable Perl code.  The "almost"
54           comes from the fact that theme names are left as is.
55

CONSTANTS

57       $RULE_INVALID_CHARACTER_REGEX
58           A regular expression that will return the first character in the
59           matched expression that is not valid in a rule.
