Adept 2.7

Adept 2.7 has been released!

Sponsors:

• Special thanks to Fernando Dantas for sponsoring Adept ❤️

List of changes in Adept 2.7

Language:

• Added ability to mark types as no discard using the exhaustive keyword:

  • func getName() exhaustive String = "Not using this return value is a compile-time error"

• Added ability to mark functions as disallowed using = delete

  • func youCannotCallThisFunction(a, b int) int = delete

  • func youCannotCallThisFunction(a, b int) int = delete { return a + b }

  • Trying to call a disallowed function is a compile-time error.

  • Trying to assign a type regularly that has __assign__ disallowed is a compile-time error.

    • func __assign__(this *UnassignableType, _other POD UnassignableType) = delete

• Unreachable code paths are no longer required to return a value

• Added better and consistent constructors, with the new constructor keyword

  struct Rectangle (w, h float) {
      constructor(w, h float) {
          this.w = w
          this.h = h
      }
      
      constructor(size float) {
          this.__constructor__(size, size)
      }
  }
  
  func main {
      rectangle1 Rectangle(100, 50)
      
      rectangle2 Rectangle = Rectangle(75, 50)
      
      rectangle3 Rectangle
      rectangle3.__constructor__(500)
      
      rectangle4 *Rectangle = new Rectangle(640, 480)
      defer delete rectangle4
  }
  

  • Constructors automatically generate a constructor function (that has the same name as the type it's for)
  • Constructors come with a companion __constructor__ method, which can be used to call a constructor on any value
  • Constructors can use the new immediate construction syntax: my_value MyType() and new MyType()
  • Zero-initialization is still the default, constructors don't apply to naked definitions, e.g. my_value MyType is zero-initialized and not constructed.

• Trying to declare __as__ as a method is now a compile-time error (__as__ should be declared as a function)

• Changed #halt directive to exit the compiler with status code 1 instead of 0

• Added #done directive to exit the compiler with status code of 0

• Added #runtime_resource directive, which will create a project-local copy of a file (if one with the same name doesn't already exist)

  • Used to automatically supply runtime resources such as .dll files to new projects that need them

• Added classes, which are equivalent to structs except that they allow for virtual dispatch and come with a __vtable__ field.

  import basics
  
  class Shape () {
      constructor {}
  }
  
  func main {
      shape *Shape = new Shape()
      defer delete shape
      
      print(shape.__vtable__) // Will be non-zero since `value` is constructed and ready for dynamic dispatch
  }
  

  • All classes require a constructor and must be constructed in order to use dynamic dispatch / virtual methods

• Added virtual methods and virtual dispatch

  import basics
  
  class Shape () {
      constructor {}
      	
      virtual func getArea() float {
          return 0.0f
      }
  }
  
  class Rectangle extends Shape (w, h float) {
      constructor(w, h float) {
          this.w = w
          this.h = h
      }
      
      override func getArea() float {
          return this.w * this.h
      }
  }
  
  func main {
      shape *Shape = new Rectangle(100.0f, 50.0f)
      defer delete shape
      
      print(shape.getArea())
  }
  

  • Virtual methods can be used alongside existing features such as regular polymorphism, default values, and more

• Added optional foreign prefix for enums, which disables the requirement to use the EnumName:: prefix to refer to enum variants. This is useful when writing bindings for C libraries, as enum variants are already named to be unambiguous.

  // ...
  
  foreign enum CURLUPart (
      CURLUPART_URL,
      CURLUPART_SCHEME,
      CURLUPART_USER,
      CURLUPART_PASSWORD,
      CURLUPART_OPTIONS,
      CURLUPART_HOST,
      CURLUPART_PORT,
      CURLUPART_PATH,
      CURLUPART_QUERY,
      CURLUPART_FRAGMENT,
      CURLUPART_ZONEID /* added in 7.65.0 */
  )
  
  func main {
      // Without `foreign` prefix, we would have to do:
      part1 CURLUPart = CURLUPart::CURLUPART_URL
      
      // With `foreign` prefix, we're allowed to do:
      part1 CURLUPart = CURLUPART_URL
  }
  

• Resolved issues with loose polymorphism

  • $T and $~T are no longer equivalent
    • $T and $~T are now only equivalent if at the top level of a type. For example, func add(a, b $T) $T is equivalent to func add(a $T, b $~T) $T, but func add(a, b <$T> Container) <$T> Container is not equivalent to func add(a <$T> Container, b <$~T> Container) <$T> Container.

• Added new polymorphic prerequisite $T extends MyClass, e.g. func useShape(shape <$T extends Shape> Optional) { ... }

• Changed __unix__ to now properly be true when compiling for macOS

• Lots of bugs fixes

Standard Library:

• Removed outdated lowercase constructors for types in 2.7/ standard library
  • array(items, length) removed in favor of Array(items, length)
  • list(items, length, ownership) removed in favor of List(items, length, ownership)
  • string(null_terminated_string) removed in favor of String(null_terminated_string)
  • captColor(r, g, b, a) removed in favor of CaptColor(r, g, b, a)
  • etc.
  • Outdated programs that use these old constructor names will need to have an earlier version of the standard library specified in order to compile (e.g. with --std=2.6 or pragma default_stdlib '2.6' or have pragma compiler_version '2.6')
• Some types such as Pair are now records instead of plain structs
• Trying to use a donor String, List, or Grid value after it has been donated now is now a runtime error (enabled by default)
• StringOwnership::DONATED has been renamed to StringOwnership::DONOR
• Added give() method for String, List, and Grid, which is equivalent to commit() with ownership required. Not having ownership to give is a runtime error by default.
• Added __assign__ for Optional, so that their internal values are not improperly assigned when has is false

Behind the Scenes Changes:

• Completely rewrote lexer
• Cleaner compiler code

Adept 2.7 is also backwards compatible with most programs written in versions 2.0 through 2.6
