Introduction

Compiler errors and runtime errors are reported via events. ICompiler dispatches CompilerErrorEvents for compiler errors and IScript dispatches ScriptErrorEvents for runtime errors.

Details

Assuming an initialized instance of ICompiler already exists:

Compile Error

import com.newgonzo.scripting.ICompiler;
import com.newgonzo.scripting.IScript;
import com.newgonzo.scripting.events.CompilerErrorEvent;

// listen for compile errors
compiler.addEventListener(CompilerErrorEvent.COMPILER_ERROR, compilerError);

var invalid:String = "trace(";

var script:IScript = compiler.compile(source);

function compilerError(event:CompilerErrorEvent):void
{
  trace("COMPILER ERROR: " + event);
}

// traces "COMPILER ERROR: [CompilerErrorEvent(error=CompilerError: ESCompiler:1: String or identifier required, found rightbrace)]"

Runtime Error

import com.newgonzo.scripting.ICompiler;
import com.newgonzo.scripting.IScript;
import com.newgonzo.scripting.events.ScriptErrorEvent;

var invalid:String = "trace(invalid);";

var script:IScript = compiler.compile(source);

script.addEventListener(ScriptErrorEvent.SCRIPT_ERROR, scriptError);

// run the script
script.load();


function scriptError(event:ScriptErrorEvent):void
{
  trace("RUNTIME ERROR: " + event);
}

// traces "RUNTIME ERROR: [ScriptErrorEvent(error=ScriptError: Error #1065: Variable invalid is not defined.)]"
