Available on master branch Unreleased

Version 2.0.0.0

** Released on 2016-10-14 New

  • Visual Studio Code debugging now supports multiple script objects
  • Support for .NET Core
  • Support for Unity WebGL
  • Support for WSA targets at source level
  • Improved support of other Unity targets
  • Unity package is now included inside distribution zip file (easier to use and faster to deploy than the asset store)
  • Stripped source distribution is now included inside distribution zip file (to ease custom framework builds)
  • Improved compatibility layer for API changes between .NET framework releases
  • Fixed : NuGet packages for VsCode debugger were broken
  • Fixed : VsCode debugger breakpoints might get missed
  • Fixed : VsCode debugger keeps the program running on exit because of a foreground thread
  • Fixed an issue where hardwiring a delegate generated invalid ctor calls #158 (thanks issingle)

Version 1.8.0.0

** Released on 2016-10-07

  • Support for debugging from Visual Studio Code (see here for details)
  • Serialization/Deserialization of tables and objects to JSON
  • JSON library added
  • Unity Asset Store package - now in "pending approval" stage
  • Various (breaking) changes to debugger infrastructure
  • Added some overloads to Script.DoFile, Script.DoString and Script.DoStream methods
  • Fixed : minor bug in table serialization of string fields

Version 1.7.0.0

** Released on 2016-10-03

  • Behaviour of C# functions called using the colon ':' operator can be chosen using the ColonOperatorClrCallbackBehaviour Script option (see also #149).
  • Vastly improved performance of table insertion #144 (thanks nshibano)
  • Vastly improved performance of table appends (somewhat related to #144)
  • Added disposability to debugger host chain #150 (thanks aravol)
  • Fixed : require didn't always skip loading already loaded modules
  • Fixed : Table.Clear crashing #151 (thanks JokieW)
  • Fixed : Error loading moonsharp.exe #148 (thanks InfectedBytes)
  • Fixed : Script processing fails on files smaller than 8 bytes ... #145 (thanks nagblock)

Version 1.6.0.0

** Released on 2016-05-16

  • Added a RethrowExceptionNested option to Script.GlobalOptions which instead of doing a plain re-throw of exceptions, embeds them in the InnerException property of a new exception object. Useful to simplify handling (newer exceptions are automatically decorated) and to preserve stack traces on Mono/Unity (annoying Mono bug..)
  • Removed _ENV tables from serialized bytecode (thanks Matija Hustić)
  • Added non-standard contains, startsWith and endsWith methods to string module.
  • Refactored the Table class's Set/Get methods to be more symmetrical, with added RawGet, Remove and Append methods (thanks Francois Retief)

  • Fixed : Events missing add or remove methods could cause a NullReferenceException
  • Fixed : __newindex metamethod can completely break the MoonSharp VM (bad bad bug)
  • Fixed : Lexer matched non-western digits as valid numbers (if you are a .NET developer, recommended read: this - ouch)

Version 1.5.0.1

** Released on 2016-02-09

  • Hardwiring.
  • DynValue.NewPrimeTable() to create a prime table, that is a table which can be shared between Scripts
  • Special syntax for table constructor ${ ... } which can be used to declare a "prime" table.
  • Serialization of prime tables as exchange data format
  • Created IRegistrationPolicy interface to customize the type registration process
  • Fixed: changing the first upvalue of a chunk did not change the _ENV of that chunk (#126)
  • Fixed: UserData.RegisterAssembly was not registering types correctly if no assembly was passed

Version 1.2.1.0

** Released on 2016-01-24

  • Support for Proxy objects
  • Support for sub-objects in property assigners
  • MoonSharpHide attribute to specify members not to be exposed to Lua scripts
  • MoonSharpVisible attribute now can be added to constructors too
  • MoonSharpHidden attribute as a shortcut for MoonSharpVisible(false) also in an easier namespace to use
  • UnityAssetScriptLoader has new constructors which don't require reflection use (to ease IL2CPP porting)
  • Fixed a weird bug with using the same destination variable twice in a for-iterator statement (while syntax is parsed correctly, behavior is still undefined as it's not really correct Lua)

Version 1.1.0.0

** Released on 2015-12-08

  • New feature: Preemptive coroutines to limit time spent in scripts while preserving state.
  • Added Script parameter to custom converters - this might break compatibility if you were getting custom converters. (Issue #118)

  • Added a DebuggerEnabled property so that the debugger can be disabled for specific scripts invocations (issue #113)
  • Script loading now uses an access mode which allows shared operations (thanks Atom0s)
  • Fixed: Capturing varargs in table from inner scope causes null ref exception (issue #110)
  • Fixed: Event re-registration might now work (issue #112)
  • Fixed: error messages in load and loadfile functions were at times unhelpful (issue #107)

  • Partial support to directly use a Lua coroutine as a Unity3D coroutine
  • ScriptLoaderBase and all its child can optionally ignore the LUA_PATH global
  • The REPL interpreter and ReplInterpreterScriptLoader now consider the LUA_PATH_5_2 environment variable
  • Fixed a bug on Unity3D where UnityAssetsScriptLoader was not available on WSA apps
  • Fixed a bug where using AutoRegistration break automatic delegates interop
  • Fixed some issues on explicitely registered collections (See github issue #88)
  • Fixed documentation issues

Version 0.9.2

Released on 2015-03-31

  • Support for lambda style anonymous function as done by metalua (|x,y| x*y for function(x,y) return x*y end )
  • Support for interop with overloaded methods (see note 1 below)
  • Support for interop with fields (see note 2 below)
  • Support for interop with methods having ref/out parameters (see note 2 below)
  • Support for interop with C# indexers (incl. language extension)
  • Support for interop with overloaded operators and metamethods on userdata
  • Support for interop with extension methods
  • Partial support for iterating over coroutines with a for..each loop
  • Proper REPL interpreter and facilities implemented
  • FIXED: % operator was calling the __div metamethod instead of __mod

Note 1: overloaded methods add computational complexity at every call to dispatch to the correct method. While caching exists to improve performance, please try to avoid that.

Note 2: setting a field and methods with ref/out paramenters at the moment always use reflection, whatever the InteropAccessMode is. Use properties and/or methods returning DynValue tuples for faster access.

This is a bug fix release over 0.8.0:

  • A lot of bug-fixes regarding error handling on nested C# calls and coroutines
  • A bad bug involving a miscalculation of table length has been fixed (See issue #38)

Version 0.8.0

Released on 2014-12-11

  • 'os', 'io' and 'file' libraries completed. Note that in Unity some functionality is not supported.
  • Parts of the 'debug' library completed. This has been done for compatibility sake, as debuggers are implemented differently in MoonSharp.
  • Improved error messages
  • Improved options management [breaking change!]

  • Fixed some license issues here and there

Version 0.6.0

Released on 2014-10-20

  • Changed "Closure" property of CallbackFunction from Table to be named AdditionalData and being an Object
  • Removed some deprecated methods from ScriptExecutionContext
  • Lots of optimizations
  • Fixed a bug where strings containing some escape sequences were not parsed correctly.
  • Improved syntax error messages
  • Made ':' calls work the same as '.' calls on userdata
  • String library completed, with some methods importing code from KopiLua, ported to 5.2 standard
  • Fixed some bugs in the parsing of string literals escape codes
  • Started a small wrapper to interface with code using the classic stack-based API (UniLua, KopiLua or Lua itself).
