与IronPython的一个C＃应用程序的书面Simplfying DSL [英] Simplfying DSL written for a C# app with IronPython

问题描述

由于从<一个建议href="http://stackoverflow.com/questions/1324904/extending-c-net-application-build-a-custom-scripting-language-or-not">$p$pvious问题，我忙着出来的IronPython，IronRuby和嘘声来创建一个DSL为我的C＃应用​​程序。停止一个是IronPython的，由于较大的用户和知识库。如果我能得到的东西很好地在这里工作，我就可以停下来。

Thanks to suggestions from a previous question, I'm busy trying out IronPython, IronRuby and Boo to create a DSL for my C# app. Stop one is IronPython, due to the larger user and knowledge base. If I can get something to work well here, I can just stop.

下面是我的问题：

我希望我的IronPython的脚本可以访问功能的一类被称为库。现在，我可以将集添加到IronPython的运行时间，并通过执行该语句在我创建的范围导入类：

I want my IronPython script to have access to the functions in a class called Lib. Right now I can add the assembly to the IronPython runtime and import the class by executing the statement in the scope I created:

// load 'ScriptLib' assembly
Assembly libraryAssembly = Assembly.LoadFile(libraryPath);
_runtime.LoadAssembly(libraryAssembly);

// import 'Lib' class from 'ScriptLib'
ScriptSource imports = _engine.CreateScriptSourceFromString("from ScriptLib import Lib", SourceCodeKind.Statements);
imports.Execute(_scope);

// run .py script:
ScriptSource script = _engine.CreateScriptSourceFromFile(scriptPath);
script.Execute(_scope);

如果我想运行库:: PrintHello，这仅仅是一个Hello World风格的说法，我的Python脚本包含：

If I want to run Lib::PrintHello, which is just a hello world style statement, my Python script contains:

Lib.PrintHello()

或者（如果它不是静态的）：

or (if it's not static):

library = new Lib()
library.PrintHello()

我怎样才能改变我的环境，这样我就可以有在Python脚本基本statments是这样的：

How can I change my environment so that I can just have basic statments in the Python script like this:

PrintHello
TurnOnPower
VerifyFrequency
TurnOffPower
etc...

我想这些脚本是简单的非程序员来写。我不希望他们必须知道什么是类或者它如何工作的。 IronPython的是真的就在那里，这样像，一些基本的操作去做，如果和基本功能的定义不要求我写一个编译器，我的DSL。

I want these scripts to be simple for a non-programmer to write. I don't want them to have to know what a class is or how it works. IronPython is really just there so that some basic operations like for, do, if, and a basic function definition don't require my writing a compiler for my DSL.

推荐答案

您应该能够做这样的事情：

You should be able to do something like:

var objOps = _engine.Operations;
var lib = new Lib();

foreach (string memberName in objOps.GetMemberNames(lib)) {
    _scope.SetVariable(memberName, objOps.GetMember(lib, memberName));
}

这会得到所有成员的LIB objec，然后将它们注入了ScriptScope。这样做是瓦特/ Python的ObjectOperations类，让你下车成员将Python的成员。所以，如果你那么做类似的事情W¯¯/ IronRuby的同一code应该主要工作。

This will get all of the members from the lib objec and then inject them into the ScriptScope. This is done w/ the Python ObjectOperations class so that the members you get off will be Python members. So if you then do something similar w/ IronRuby the same code should basically work.
