0.13.0

Breaking Changes

• Enum destructuring within case statements now uses parentheses and commas instead of whitespaces.

  Given this enum:

  enum Status {
    LoggedIn(Time, User)
    LoggedOut
  }

  Destructuing before:

  case (maybe) {
    Status::LoggedIn time user => true
    Status::LoggedOut => flase
  }

  After:

  case (maybe) {
    Status::LoggedIn(time, user) => true
    Status::LoggedOut => flase
  }

  This was a necessary step to make nested destructuring work.

Language

• #81 #451 Added line comments: 🎉

  // Line comment
  fun render : Html {
    ...
  }

• Added @inline directive which inlines a text file into Mint code as String:

  @inline(path/to/file.html) /* String */

• #418 #419 Added index variable to the for loops:

  /* Iterating over Array(item) or Set(item). */
  for (item, index of array) {
    ...
  }
  
  /* Iterating over Map(key, value). */
  for (key, value, index of map) {
    ...
  }

• #437 Tuples can be destructured recursively (@matthewmcgarvey):

  case ({"A", {"B", "C"}}) {
    {a, {b, c}} => c
    => ""
  }
