Samarium 0.5.0

Added

• collections.Queue now supports membership checking
• collections.Set now uses the built-in set-based Array operations (working with small sets can be up to 3,600x faster)
• Files are now iterable
• iter.filter and iter.map now adapt to functions based on their number of parameters
• math.is_int
• math.ceil
• math.floor
• math.round
• math.to_bin (to replace Integer$)
• Number type (in place of the Integer type):
  • supports floats
  • x$ now floors the number
  • x -- y now does true division rather than floor division
• Number literals, using ` as the decimal point (meaning that it's no longer ignored by the tokenizer)
• Nulls can now be cast to Numbers
• Parallel assignment
• random.sample now supports slices
• Set-based Array operations:
  • -x returns a copy of x with duplicates removed
  • x -- y ("difference") tries removing elements of y from x, even if they're not present
  • x --- y removes all duplicates of y in x
  • x | y ("union") creates an array with elements that appear in either x or y (duplicates possible)
  • x & y ("intersection") creates an array with elements that appear in both x and y (duplicates possible)
  • x ^ y ("symmetric difference") creates an array with elements that appear in either x or y, but not both (duplicates possible)
• Slices are now hashable
• String -- String (old String - String behavior)
• String++ (equivalent to String ++ /\)
• string.split now accepts multiple separators
• String→Number now supports scientific notation
• string.split_lines
• Strings can have their characters shifted by adding or subtracting Integers
• types.Frozen

Changed

• Flipped argument order for iter.reduce
• Improved Array/Slice/String index typechecking
• Improved CLI error messages
• Improved error messages
• Improved File.__str__
• Improved implicit null detection
• Improved slice transpilation
• random.shuffle now does type checking againast slices
• String - String now removes only the first occurence
• The main function is no longer required
• Two or more consecutive logical NOTs are now considered a syntax error

Fixed

• Comments are now correctly tokenized
• Fixed ... special method not being detected
• Fixed Slice→Array construction
• Fixed some yield statements crashing the transpiler
• Functions are now correctly displayed in Arrays/Tables
• Logical NOT (~~) no longer lets Python's bool slip in
• Multiline strings are now correctly tokenized
• Number ++ String is no longer detected as an invalid operation
• Slices are now correctly detected as objects directly after scope exit
• String.__repr__ now correctly handles escape sequences
• Type(a) != B no longer yields incorrect results
• UserAttrs can no longer show up when using x!?
• Varargs functions now work correctly with recursive functions and decorators

Removed

• collections.StaticArray
• Integer type

The Examples page was also updated with new examples.
