Changelog

Update 1.1

• Structs

  struct House {
      var name = "House"
      var color = "Red"
      var size = 100
  
      func getname() {
          return name
      }
  
      func getcolor() {
          return color
      }
  }
  
  var house = House()
  
  log house.getname()

• Better syntax errors

  var name = "Acho"
  var name = "acho"
  
  /* console
  Syntax error on line 2
  "name" is already defined
  
  2  |  var name = "acho"
            ~~~~
  */

• Fixes various bugs

Update 1.2

• comments

  // this is a comment

• += -= *= /= ++ syntax sugar

  var variable = 10
  
  variable++
  
  variable += 1
  variable -= 2
  variable *= 2
  variable /= 4

• Static functions

  struct SoundManager {
      static var volume = 10
      static var sounds = [
          Sound()
          Sound()
          Sound()
      ]
  
      static var playSound(index) {
          SoundManager.sounds[index].play()
      }
  }
  
  SoundManager.playSound(2)

• Changed 'input' to 'prompt'

  prompt "what's your name"

• Modules and importing

  // io.kg
  // ---------------------------
  func print(value) {
      log value
  }
  
  func input(q) {
      var result
      prompt q -> result
      return result
  }
  // ---------------------------
  
  // test.kg
  // ---------------------------
  import io
  
  var name = io.input("what's your name? ")
  io.print("hello, " + name + "!")
  // ---------------------------
  
  /* console
  what's your name? acho
  hello, acho!
  */

• Better execution of kang2 scripts

  • node app.js <your kang2 script>.kg

• Visual Studio Code extension

  • Get decent syntax highlighting and icons by downloading the Kang2 VSC extension from the extension store!

Update 1.3

• Primitive types

  • Every variable has a type with standard functions (std folder)

  var string = "hey"
  log string.split()
  
  func log_char(char) {
      log char
  }
  
  string.split().foreach(log_char)

• Active references

  • Reference values with &, which will bind the reference to the original variable, making changing one, reflect the changes on both
  • Unreferencing values with @, to get the actual value and change it unrelated to the original variable

  var value = 10
  var ref = &value
  
  value = 20
  log @ref
  
  ref = 30
  log value
  
  log @ref + 10

  [console]
  20
  30
  40
  

• Advanced loop

  • More advanced loops

  loop var i = 0, i < 10, i++ {
      log i
  }

• Fixed a bunch of problems with the syntax highlighting

• Fixed lots of bugs, making the language more stable

• Made a small std library for most types
