Some (newer) Haxe language features are not supported

[johhnry]

Hi (again),

Here are the recent features that are not well handled by the parser:

• implements keyword with interfaces:

• the final access modifier on classes:

• Generic parameter with the Array type (for example) in a method (same for typedef Ints = Array<Int>;):

• Usage of this inside a class method:

• ERROR in if/else statement:

And also (giving error when inspecting the tree-sitter tree):

• Passing anonymous structures to method arguments:

interface ITest {
  function accept(json:{a:Int, b:Float}):Bool;
}

• Array comprehension with range expression:

var a = [for (i in 0...5) i];

• the using keyword for static extensions:

using ArrayExtensions;

• Using property read/write access (the example is from the documentation):

class Main {
    public var x(default, null):Int;

    static public function main() {}
}

• Abstract classes:

abstract class Vehicle {}

Thanks!

Hey thanks for the clean feedback, I'll try to get to some of this soon.

I closed this with PR, version is on NPM @ 0.4.0.

Let me know if you see any of these again, there should be tests covering all cases, if not, I would love if you could just add the tests (in the tests/corpus/*.txt whereever it seems to make sense) and make a PR even if it's failing just to help me ensure all cases are covered.

Anyhow, this should fix all these, and thanks again for the through bug report.

@vantreeseba thank you so much it will improve the DX a lot!
