ArkScript v4.0.0-rc6

Added

• fuzzing step in the CI
• better error reporting on unknown import
• check on number of arguments passed to type
• warning when the formatter deletes comment(s) by mistake
• check on arguments passed to list, concat, append and friends to only push valid nodes (that produces a value)

Changed

• fixed a bug in the compiler where one could pass a non symbol to let, mut or set, resulting in a compiler crash
• fixed a bug in the macro processor where one could pass an unknown symbol to argcount and crash the processor
• fixed a bug in the compiler where one could pass something other than a list to (fun) as the argument block, resulting in a crash
• fixed a bug in the compiler generating not callable functions
• fixed a bug in the macro processor generating invalid let / mut / set nodes
• fixed a bug in the macro processor allowing out of bounds access with ($ test (@ [1 2 3] -5))
• fixed a bug in the vm which wrongfully allowed self concat in place: (concat! lst lst)
• fixed a bug in the compiler where one could "use" operators without calling them: (print nil?)
• fixed a bug in the compiler allowing the use of operators without any argument: (+)
• fixed a bug in the vm during error reporting when a non-function was used as a function
• refactored code inside the bytecode reader to promote code reuse
• fixed a bug in the compiler generating invalid while nodes
• fixed a bug when passing the wrong number of arguments to a function inside an async call was crashing the VM because the function couldn't be named
• fixed a bug in the compiler generating invalid fun nodes
• fixed a bug when generating let, mut or set nodes inside macros with an invalid node type
• fixed a bug when reading invalid UTF8 codepoints in the parser caused out of bounds reads
• fixed a bug with recursive macro, exhausting the stack space due to recursive evaluation
• futures can be awaited again, they will return nil on all the tries
• checking for reused argument name in macros during parsing
• enhanced comment after node handling in macros
• adding a hard limit on package names length (255 characters, to comply with posix limits)
• disallow passing invalid nodes as arguments to functions and operators
• checking for unevaluated spread inside macros
• checking for invalid symbols when defining a function through a macro
• added a max macro unification depth

Removed

• removed useless \0 escape in strings
