Current Version: 0.8 beta

Breaking Changes

• Keyword switch is now match
• Keyword case is removed (in favor of == patterns)
• Unary .. operator is no longer allowed (for example ..10 now needs to be written as 0..10)
• The has operator has been replaced with in (with the order flipped)

New Features

• Return types for macros with (arguments) -> return_type { ... } syntax
• You can spread an array in another array with .. syntax:
• spwn eval subcommand for running code in the console

b = [3, 4]
$.assert([1, 2, ..b, 5] == [1, 2, 3, 4, 5])

• Unzip arrays with *[...] syntax:

a = [1, "a"]
b = [2, "b"]
c = [3, "c"]
$.assert([\*[a, b, c]] == [[1, 2, 3], ["a", "b", "c"]])

• Destructuring additions, including dictionary destruction, and destruction of the syntax mentioned above (.. and *[...])
• Big expansion to the pattern system:
  • is operator for matching any value to a pattern (10 is @number // true)
  • using most boolean operators as unary operators now yield a pattern:
    • ==val will match any value that equals val
    • !=val will match any value that does not equal val
    • >val will match any value that is greater than val
    • <val will match any value that is less than val
    • >=val will match any value that is greater than or equal to val
    • <=val will match any value that is less than or equal to val
    • in val will match any value that is in val
  • & operator for combining two patterns, so that the resulting pattern requires the value to match both patterns
  • _ pattern, which matches any value (wildcard)
  • pattern ternary operator, which returns a value if it matches a pattern, and otherwise returns the default value:

    10 if is >5 else 0 // 10
    4 if is >5 else 0 // 0

• You can now remove stuff from dictionaries with dict.delete(key)

STD Library Features

• @chroma type for color values, this type is now used in for example color triggers instead of RGB arguments
• level global variable for reading the objects in the current level
• @log and @runtime_log types for debug logging to the console or at runtime
• @set type for making groups of objects read from the level that can be rotated, scaled, and pasted in the level
• Changes and improvements to many existing types (see the docs)
