Perl::Critic::Policy::Modules::RequireFilenameMatchesPacUser(Contributed Perl DocPerl::Critic::Policy::Modules::RequireFilenameMatchesPackage(3pm)NAME
Perl::Critic::Policy::Modules::RequireFilenameMatchesPackage - Package declaration must match filename.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The package declaration should always match the name of the file that contains it. For example, "package Foo::Bar;" should be in a file
called "Bar.pm". This makes it easier for developers to figure out which file a symbol comes from when they see it in your code. For
instance, when you see "Foo::Bar->new()", you should be able to find the class definition for a "Foo::Bar" in a file called Bar.pm
Therefore, this Policy requires the last component of the first package name declared in the file to match the physical filename. Or if
"#line" directives are used, then it must match the logical filename defined by the prevailing "#line" directive at the point of the
package declaration. Here are some examples:
# Any of the following in file "Foo/Bar/Baz.pm":
package Foo::Bar::Baz; # ok
package Baz; # ok
package Nuts; # not ok (doesn't match physical filename)
# using #line directives in file "Foo/Bar/Baz.pm":
#line 1 Nuts.pm
package Nuts; # ok
package Baz; # not ok (contradicts #line directive)
If the file is not deemed to be a module, then this Policy does not apply. Also, if the first package namespace found in the file is
"main" then this Policy does not apply.
CONFIGURATION
This Policy is not configurable except for the standard options.
