Module Pattern - language feature

Example from 1 languages: Java

// Package = directory. Java classes can be grouped together in packages. A package name is the same as the directory (folder) name which contains the .java files. You declare packages when you define your Java program, and you name the packages you want to use from other libraries in an import statement.
// The first statement, other than comments, in a Java source file, must be the package declaration.
// Following the optional package declaration, you can have import statements, which allow you to specify classes from other packages that can be referenced without qualifying them with their package.
// This source file must be Drawing.java in the illustration directory.
package illustration;
import java.awt.*;
public class Drawing {
 // ...
}

Example from 1 languages: C#

// In C#, namespaces are the semi-equivalent of Java's packages.
namespace com.test
{
   class Test {}
}

Example from 1 languages: Julia

module MyModule
using Lib

using BigLib: thing1, thing2

import Base.show

export MyType, foo

struct MyType
    x
end

bar(x) = 2x
foo(a::MyType) = bar(a.x) + 1

show(io::IO, a::MyType) = print(io, "MyType $(a.x)")
end

Example from 1 languages: Fortran

module constants
implicit none

   real, parameter :: pi = 3.1415926536
   real, parameter :: e = 2.7182818285
   
contains
   subroutine show_consts()
      print*, "Pi = ", pi
      print*,  "e = ", e
   end subroutine show_consts
   
end module constants


program module_example
use constants
implicit none

   real :: x, ePowerx, area, radius
   x = 2.0
   radius = 7.0
   ePowerx = e ** x
   area = pi * radius**2
   
   call show_consts()
   
   print*, "e raised to the power of 2.0 = ", ePowerx
   print*, "Area of a circle with radius 7.0 = ", area
   
end program module_exampl

Example from 1 languages: Racket

(module nest racket
   (provide (for-syntax meta-eggs)
            (for-meta 1 meta-chicks)
            num-eggs)
   (define-for-syntax meta-eggs 2)
   (define-for-syntax meta-chicks 3)
   (define num-eggs 2))

Example from 1 languages: OCaml

(* In OCaml, every piece of code is wrapped into a module. *)
(* amodule.ml *)
let hello () = print_endline "Hello"
(* bmodule.ml *)
Amodule.hello ()

Example from 1 languages: C3

module my_module::submodule;
...

Example from 1 languages: Speedie

module App
 function Path (|string|)
  // return the app's path here
