NAME

6       Perl::Critic::Policy::Subroutines::ProtectPrivateSubs - Prevent access
7       to private subs in other packages.
8

AFFILIATION

10       This Policy is part of the core Perl::Critic distribution.
11

DESCRIPTION

13       By convention Perl authors (like authors in many other languages)
14       indicate private methods and variables by inserting a leading
15       underscore before the identifier.  This policy catches attempts to
16       access private variables from outside the package itself.
17
18       The subroutines in the POSIX package which begin with an underscore
19       (e.g. "POSIX::_POSIX_ARG_MAX") are not flagged as errors by this
20       policy.
21

CONFIGURATION

23       You can define what a private subroutine name looks like by specifying
24       a regular expression for the "private_name_regex" option in your
25       .perlcriticrc:
26
27           [Subroutines::ProtectPrivateSubs]
28           private_name_regex = _(?!_)\w+
29
30       The above example is a way of saying that subroutines that start with a
31       double underscore are not considered to be private.  (Perl::Critic, in
32       its implementation, uses leading double underscores to indicate a
33       distribution-private subroutine-- one that is allowed to be invoked by
34       other Perl::Critic modules, but not by anything outside of
35       Perl::Critic.)
36
37       You can configure additional subroutines to accept by specifying them
38       in a space-delimited list to the "allow" option:
39
40           [Subroutines::ProtectPrivateSubs]
41           allow = FOO::_bar FOO::_baz
42
43       These are added to the default list of exemptions from this policy.
44       Allowing a subroutine also allows the corresponding method call. So
45       "FOO::_bar" in the above example allows both "FOO::_bar()" and
46       "FOO->_bar()".
47

HISTORY

49       This policy is inspired by a similar test in B::Lint.
50

BUGS

52       Doesn't forbid "$pkg->_foo()" because it can't tell the difference
53       between that and "$self->_foo()".
