Subs resolution status

One of the most important goals of this plugin was to unleash powerful IDEA refactoring into the Perl's world. But, it's easier to say... :)

Currently

At the moment, only obvious subs invocations are resolved:

• sub() - for defined/declared/imported subs or typeglobs.
• Package::sub() - for defined/declared/imported subs or typeglobs.
• Package->sub() - with inheritance
• sub Package() - works, but glitchy, not recommended
• $self->sub() - with inheritance
• SUPER::sub() - with inheritance
• $obj->sub() - with inheritance, if $obj has been declared with specific type or assigned to sub return value with known result.

my Foo::Bar $obj;
...
$obj->method(); # we know that it's Foo::Bar method

my $other_obj = Foo::Baz->new();

$other_obj->method(); # we know that it's a Foo::Baz method

• Foo::Bar->new->method->other_method - with inheritance. To make this work, methods should be annotated with #@returns.

What is planned

• Proper resolve for lexical subs. For now they are treated as regular ones
• Implement and improve heuristic to understand Perl code
• Annotation files, to be able to define return values and prototypes for packages without them
• subs annotations for structures of objects, like:
  • #@returns [Foo::Bar] - returns arrayref of Foo::Bar objects
  • #@returns {Foo::Bar} - returns hashref with Foo::Bar objects as values
