Refer to class inside of static method without using its name

Does that help You can use the this keyword to refer to the object itself.
See example below:
code :
class FooBar {
  static foo() {
    return 'foo';
  }

  static bar() {
    return 'bar';
  }

  static foobar() {
    return this.foo() + this.bar();
    // self::foo() + self::bar() would have been more desirable.
  }
}

const res = FooBar.foobar();
console.log(res);

How to let a class variable in python refer to a static method of the same class?

it fixes the issue You are right about the problems of referencing the static method during class creation. Test isn't in the namespace yet, and even if you define ref below testmethod, the static method definition magic isn't complete. You can, however, patch the class after its created:
code :
class reg(cmd): 

    bla = {
        'def': [ ... ],
        'rem': [ ...,
            PIPE.return_response(fail_callback=HERE_I_NEED_THE_REF),
            ...
        ]
    }

    @classmethod
    def testmethod(cls, aco):
        print "i want to see this on fail"

Test.ref["rem"][??] = PIPE.return_response(fail_callback=Test.testmethod)

Why can't I refer enclosing class's non-static var from its inner class's non-static method?

may help you . This is because your nested class a is not an inner class of TestNested. It is a static nested class, meaning that it is not linked to a particular instance of TestNested.
code :
TestNested.a a=new TestNested.a();

What is the best way to refer to a static method from another static method of the same class in Rust?

I wish did fix the issue. The Rust designers have made the following choice: everything related to the scope is explicit. So, just as you must type self to call a member function from another member function: self.foo(), you must call a static member with Self: Self::bar().
I think that it is the case because self could not be implicit: indeed it had to be added as a parameter either by value or borrowed, unlike in Java where this is always taken by value. Thus, because self was already an explicit parameter, it was needed as an explicit caller for consistency.
code :
struct Struct;

impl Struct {
    fn foo(&mut self) {
        self.consume();
    }

    fn consume(self) {}
}
error[E0507]: cannot move out of borrowed content
 --> src/main.rs:5:9
  |
5 |         self.consume();
  |         ^^^^ cannot move out of borrowed content

Refer to own class in a static method

Hope that helps Yes, use @classmethod instead of @staticmethod. The whole point of @staticmethod is to remove the extra class parameter if you don't need it.

js class static method refer to self (like self in php)

With these it helps A class is nothing but a function object. Static methods are nothing but function properties on that object. Whenever you call obj.method(), this refers to the object inside that function.
So if you call the method with User.greet(), this will refer to the function object User.
