roadmap

Milestone 1 (completed 4/1/22)

• Arrow Functions
• ** operator for pow
• If (curly brackets implemented, need single statement with semicolon variant)
• For Loops - iterators. (Need to see how the table without pairs call works with the MoonSharp default iterator)
• For Loops - C style with conditions. (New parser concept).
• do/while loops (try and make not conflict with lua’s do-end scope blocks).
• While loops
• Repeat loops
• Functions with curly bracket { } syntax
• Single-line comments
• Multiline comments
• let/var alias for local
• Tables using ‘:’
• String literal keys for table init syntax
• Square bracket list syntax
• Ternary Expression (CLike only)
• Unary ! negation (TBC)
• && (alias for and)
• || (alias for or)
• Compound assignment *= += -= /= **= ..= %=
• Overloaded + operator that tries to coerce to string if it isn’t a number
• .. replaced with + operator
• Label syntax (CLike only)
• Increment/Decrement shorthand. CLike only, breaks Lua comments

Milestone 2 (completed 4/5/22)

• Template literals `` (equivalent to $"" + multiline support in c#)
• Replace # with .length, free # for other uses
• Ditch Moonsharp’s | lambda | syntax, free pipe for bitwise & implement bitwise operators
• Nill coalescing operators
  • ??= (nill coalescing assignment)
  • ?!= (inverse nill coalescing assignment)
  • ?. (nill coalescing member access)
  • ?[] (nill coalescing element access)
  • ?? (nill coalescing)
  • ?! (inverse nill coalescing)
• null as alias for nil
• this as alias for self

Milestone 3 (completed 5/5/22)

• declaration hoisting.
• implicit "self/this". Spec in draft, see Implicit this proposal for details
• self call with dot instead of double colon. Specced in implicit "self/this".
• annotations. See Annotation proposal for details.
• default params. See #18

Milestone 4 (started 5/6/22)

• switch
• razor-esque syntax, Moonsharp.Templating assembly. See Razor like templating proposal for details
• preprocessor See Preprocessor proposal
• first-class ranges See Ranges proposal
• prototype methods "TEST".lower()

Milestone 5 (completed 6/3/22) - 1.0 FEATURE FREEZE

• class syntax, oop extensions. See Object oriented extensions proposal for details.
• enums. See Enum proposal for details.
• max instructions limit

Milestone 6 (started 9/20/22)

• string lib refactor, remove legacy kopilua interop
• static fields in classes, static classes See Static classes proposal for details.
• sealed classes
• public, private fields in classes & mixins
• generic classes class C<T1, T2..>

backlog

• using/static require + relaxed quotes around require
• bytecode guards stripping with statically resolved types
• try/catch
• types as comments. See Types as comments proposal for details. Proposal rework pending.
