Alpha 3 (December 15, 2014)

Virtual machine

• A native code interface has been added, allowing platform-specific functions to be called from NewtonScript code. A NEWT/0-compatible "protoFILE" library is available that takes advantage of it.
• On OS X, NSM is now available as a native executable for the x86-64 architecture. This may provide better performance than the 32-bit x86 executable and allows 64-bit libraries to be used.
• Form parts in a special format are supported so that DyneTK can be used to create packages for NSM.
• RemoveScripts are now made use of.
• Performance has been greatly improved.
• If NSM quits because of an error, it will now display the function call stack to assist in debugging.
• Strings can now be compared with the primitive functions less-than, greater-than, less-or-equal, and greater-or-equal.
• Foreach loops are now supported. Note: "foreach deeply" is still not supported.
• The output of the built-in global functions Print and Write is now more like that of the Apple implementations and also respects the global variable printDepth.
• The global function IsReadOnly has been implemented.
• The instructions resend and resend-if-defined are now supported.
• The instruction send-if-defined now makes use of full inheritance, as it should.
• The primitive function set-class can now be used to set the class of a frame.
• The primitive function has-path is now supported.
• For frames with no class slot, the primitive function class-of now returns 'frame as in the Apple implementation.
• The global function BNot is now implemented. This is because Newton Toolkit generates a call to it where it should otherwise use the primitive function bit-not, which was also supported before.
• The built-in global functions Apply and Perform now check the types of their parameters.
• When calling a function, more sanity checks are done, such as checking whether the function being called is really a function.
• If NSM is forced to quit on the user's request (for example by pressing Ctrl+C), it will properly clean up after itself.
• The B field of parametrized instructions is now interpreted as unsigned except in the push-constant instruction, as specified by Newton Formats.
• The Haiku version is available in both GCC 2 and GCC 4 versions, allowing usage of both kinds of x86 libraries.
• Error messages are more detailed.
• Many bugs have been fixed.

Global function library

• The following functions have been added: ArrayInsert, ArrayMunger, ArrayRemoveCount, BeginsWith, BinaryMunger, DeepClone, DefGlobalFn, DefGlobalVar, Downcase, EndsWith, ExtractBytes, GetGlobalFn, GetGlobalVar, GlobalFnExists, GlobalVarExists, InsertionSort, IsAlphanumeric, IsInstance, IsSubclass, LFetch, LSearch, Map, RemoveSlot, SetOverlaps, SetRemove, SetUnion, StrCompare, StrExactCompare, StrMunger, StrReplace, SymbolCompareLex, UndefGlobalFn, UndefGlobalVar, Upcase.
• Ceiling now behaves as it should.
• SetContains now returns the correct value.
• StrPos is now faster.
• Substr now emulates the undocumented behavior of the Apple implementation for special start and length values.
