Deprecated: The noHoisting option has been removed, hoisting will always be done.
TypeScript has been updated to 3.8. See release notes for details.
Fixed class accessors not working when base class is lacking type information (#725)
Class extension code has been extracted to lualib
class A {}
class B extends A {}
A = __TS__Class()
B = __TS__Class()
-B.____super = A
-setmetatable(B, B.____super)
-setmetatable(B.prototype, B.____super.prototype)
+__TS__ClassExtends(A, B)
Generated code for class accessors is more dynamic now
class A {
get a() {
return true;
}
}
A = __TS__Class()
-A.prototype.____getters = {}
-A.prototype.__index = __TS__Index(A.prototype)
-function A.prototype.____getters.a(self)
- return true
-end
+__TS__SetDescriptor(
+ A.prototype,
+ "a",
+ {
+ get = function(self)
+ return true
+ end
+ }
+)
This change simplifies our codebase and opens a path to object accessors implementation
Errors reported during transpilation now are created as TypeScript diagnostics instead of being thrown as JavaScript errors. This makes TypeScriptToLua always try to generate valid code (even in presence of errors) and allows multiple errors to be reported in a single file:
for (var x in []) {
}
$ tstl file.ts
file.ts:1:1 - error TSTL: Iterating over arrays with 'for ... in' is not allowed.
file.ts:1:6 - error TSTL: `var` declarations are not supported. Use `let` or `const` instead.
$ cat file.lua
for x in pairs({}) do
end
Added tstl.luaPlugins option, allowing to specify plugins in a tsconfig.json file:
{
"tstl": {
"luaPlugins": [{ "name": "./plugin.ts" }]
}
}
Added support for all valid TS for ... of loop variable patterns.
Fixed a bug where spread expressions in array literals were not correctly translated:
- [1, ...[2, 3], 4]
+ [1, ...[2, 3], 4]
- ((...values) => values)(1, ...[2, 3], 4)
+ ((...values) => values)(1, ...[2, 3], 4)
Fixed Lua error when left hand side of instanceof was not a table type.
Fixed sourcemapTraceback function returning a value different from the standard Lua result in 5.1.
Fixed missing LuaLib dependency for Error LuaLib function.
Fixed several issues with exported identifiers breaking for ... in loops and some default class code.
Fixed overflowing numbers transforming to undefined Infinity, instead they are now transformed to math.huge.
