spookyfm / hscript Goto Github PK

Using latest flashdevelop, latest haxe, latest hscript, latest everything.

Code:
var script = "1+2";
var parser = new hscript.Parser();
var program = parser.parseString(script);
var interp = new hscript.Interp();
var res = interp.execute(program);

Compile options:
-lib hscript
-lib format
-swf-version 11
-D hscriptPos

Result:

Attached full output.

Without "-D hscriptPos" all works good, but not compile other part of project.

Maybe I'm doing something wrong?

It should appear in the "Compared to haXe, limitations are :" list if not

how about adding a argument to force prevent previously used locals from
getting cleared ?

172,173c172,173
<   public function execute( expr : Expr ) : Dynamic {
<       locals = new Hash();

---
>   public function execute( expr : Expr, clear : Bool = true ) : Dynamic {
>       if( clear ) locals = new Hash();


this would allow to save the state of the vm.

Test.hx:19: test("n(0xBFFFFFFF)",0xBFFFFFFF,{ n : haxe.Int32.toNativeInt });
C:\Motion-Twin\haxe\lib\hscript/1,6/Test.hx:19: characters 23-33 : This integer 
is too big to be compiled to a Neko 31-bit integer. Please use a Float instead

Provide the option to execute an expression without resetting the local 
variables.  The aim here is to allow the functionality of an REPL loop - an 
interactive console that can interact with shared haxe objects, essentially 
being run line by line.

Defaults to the existing functionality, and will not change unless "reset" is 
specified, and is false.

This is my first time submitting a patch (outside of GitHub), so if there's 
anything else I can do please let me know.

Ok, ideally I would be able to write some hScript code like:

hScript:String = "

function moveLeft()
{
    // Handle player moving left
}

function moveRight()
{
    // Handle player moving right
}
";

And then from within my Haxe be able to call
    hscript.interp().moveLeft();

I can't seem to figure out how to make it work.  It would be SUPER useful 
instead of having to write a separate script for each function...

specify source file name and line offset ( think of <script> in html ) in 
Parser.parseString
trace() now come with file and line 
Error shows file and line too

What steps will reproduce the problem?
1. Install Haxe3 and hscript 2.0
2. Try this simple example:
   for(i in 0...5) { trace("Hi"); }

What is the expected output? What do you see instead?
Expected: 
Hi
Hi
Hi
Hi
Hi

Instead I get:
Error: EInvalidIterator(IntIterator)

What version of the product are you using? On what operating system?
Haxe 3, HxCPP 3.0, hscript 2.0 - Windows 7 64bit

Please provide any additional information below.
"for" loops are broken. 
using "while" loops is ok

Haxe seems to fail to generate code when there is a break in a switch() 
statement, but removing that break changes the behavior of the code (it seems 
that the "break" is stopping the iteration that is external to the switch)

Example (taken from Parser.hx):

switch( tk ) {
    case TComma:
    case TPClose: break; //code generation will fail on this line
    default: unexpected(tk);
}

What steps will reproduce the problem?
Use this code (notice the wrong function call Math.coserror):

var script = "
    var sum = 0;
    for( a in angles )
        sum += Math.coserror(a);
    sum; 
";
try {
    var parser = new hscript.Parser();
    var program = parser.parseString(script);
    var interp = new hscript.Interp();
    interp.variables.set("Math",Math); // share the Math class
    interp.variables.set("angles",[0,1,2,3]); // set the angles list
    trace( interp.execute(program) ); 
} catch(e:Dynamic) {
    trace("script error");
}


What is the expected output? What do you see instead?
I would expect to catch the error, but instead the app closes and I get this:

What version of the product are you using? On what operating system?
Haxe 3.0.0
hscript 2.0.1
OSX 10.6.8
Target: mac

Please provide any additional information below.
It seems there's some null check missing before the Reflect function call.

Is there anything preventing hscript being put up onto haxelib for haxe3 rc2+ ?

I think in Interp.hx

function cnew( cl : String, args : Array<Dynamic> ) : Dynamic {
        return Type.createInstance(Type.resolveClass(cl),args);
    }

Should be:

function cnew( cl : String, args : Array<Dynamic> ) : Dynamic {
        return Type.createInstance(variables.get(cl),args);
    }

Otherwise constructing non-global classes fails.

The source code fails to compile using haxe 2.09 because the variable code is 
not initialized, the fix is simple:

Parser.hx -> Line 724:

Change
  var code;
to
  var code = "";

    class Test {

        static function main():Void {
            var parser = new hscript.Parser();
            var program = parser.parseString("var a = ''; a += 1; a += 1; a;");
            trace( new hscript.Interp().execute(program) ); //neko output "11" which is right, but cpp output 2.
        }
    }

What steps will reproduce the problem?
1. install hscript using haxelib
2. include it in a project, using haxe 2.10
3. build

What is the expected output? What do you see instead?
expected -> compiles
i see -> "Class not found: FastList"

This is fixed in SVN, and is basically:
        tokens = new FastList<Token>();
to
        tokens = new haxe.FastList<Token>();

.

What version of the product are you using? On what operating system?
hscript 2.0, haxe 2.10, on mac
