ros*_*mcm 13 delphi scripting pascal scripting-language remobjects
我正在为Delphi寻找一个好的免费脚本引擎.我想为应用程序添加脚本,以便我可以编写小的测试脚本.具体来说我需要:
我不需要全面的语言支持,只需要基础知识.我看到了这个:https://stackoverflow.com/questions/226135/scripting-library-for-delphi但是我假设事情已经发生了一些变化.
我想要做的就是在我的程序中添加一个备忘录组件,并在运行时向备忘录添加一个源代码片段,然后单击一个go按钮.我希望脚本能够访问我的应用程序的变量和函数.
实现这一目标的最简单方法是什么?示例程序如下.
program Project31;
uses
Forms,
Unit36 in 'Unit36.pas' {Form36};
{$R *.res}
begin
Application.Initialize;
Application.CreateForm(TForm36, Form36);
Application.Run;
end.

Jedi JVCL 还包括 TJvInterpreter,它是一个非常轻量级(小型)的解释器,但与 dwscript 相比,其功能有限。
对于非常小的(用户输入的公式,或简单的字符串和数字处理任务)JvInterpreter 对我来说效果很好。
