AS3 - 在运行时评估 - D.eval VS hurlant [英] AS3 - evaluating at runtime - D.eval vs hurlant

问题描述

我需要通过在都在运行时评估的字符串。因此，我可以这样写：

I need to pass in a string that gets evaluated at runtime. So I can write this:

var foo =  someEvalMethod ( "dataObject.someValue" )

来代替：

if ( argIn == "dataObject.someValue")
   var foo = dataObject.someValue
}

有没有人有下列评估库，或AS3更好的意见？感谢：

Does anyone have an opinion on the following evaluate libraries, or better ones for AS3? Thanks:

AS3的eval由hurlant：

AS3 eval by hurlant:

D.eval用RIA 1：

推荐答案

据我所知 AS3的eval 按hurlant是一个真正的编译器。它分析code，生成字节code和它注入到Flash Player实例中使用（通过loadBytes（）我猜的）。

As far as I know AS3 eval by hurlant is a "real" compiler. It parses code, generates bytecode and injects it to the Flash Player instance in use (through loadBytes() I guess).

D.eval 有异曲同工之妙，但它不产生字节code，它解析EX pressions，并通过自己的API动态地执行它们。

D.eval has the same purpose but it does not generate bytecode, it parses expressions and execute them dynamically through its own API.

我看的 D.eval作为一个很好的候选人为您所想要的目的。这不是一个全功能的编译器，但它有足够的API，涵盖许多简单的操作。除此之外，它是一种产品，具有公司背后，这始终是一个很好的保证。

I see D.eval as a good candidate for what you are trying to achieve. It's not a full featured compiler, but it has enough APIs that cover many simple operations. Other than that it is a product that has a company behind, which is always a good guaranty.

干杯！
