总算基本完成脚本平台 for C#2.0
刚刚才用上C#2.0,原来是这么好用啊,迫不及待的想用熟它;
最近想到平台的体系,认为自己的脚本解释器是必不可少的,于是自己抄刀;花了将近一个星期,总算建设了一个有点象样的框架了。
基本设计:
1、基于C#2.0开发
2、通过反射动态调用LIB的方法
3、完全手写的SCRIPT解释器,不用.NET的编译器做脚本解释器(完全按行模式执行)
4、提供一个基础的控制台程序(SHELL),支持批处理模式反射调用方法
5、提供DEBUG模式的SCRIPT IDE,用于简单调试(目前解释器还有点小BUG,DEBUG功能目前还未完善)
以下是SHELL的外观图:
完全模拟DOS的命令行,所有指令为反射调用的LIB方法;通过全局的配置读入:
Environment.xml配置用于存放LIB的相关信息

以上两个配置文件全部通过序列化方式生成,期间还设计到一个指令生成器;(该部分由同事完成)将DLL文件装入后自动建立这些配置信息,命令部分只获取PUBLIC方法。
批处理的调用:
BATCH FROM FILE=C:\Test.cmd
cls
print 开始测试批处理!
msgbox 这个是文本对话框
ShellExecute notepad
print 已经启动了写字板了吗?
print 开始测试表达式!
print 1+2+3+4=?
= 1+2+3+4
print 1*99=?
= 1*99
print 列表目录的指令为 dir
print 切换目录的指令为 cd
print 结束执行
print 开始测试批处理!
msgbox 这个是文本对话框
ShellExecute notepad

begin
NewLine = Chr(13) & Chr(10)
N = 9
for (i,0,10,1)
S = S & N & " x " & i & " = " & (N * i) & NewLine
next
call ShowMsg(S,"Math Board Of " & N)
end
NewLine = Chr(13) & Chr(10)
N = 9
for (i,0,10,1)
S = S & N & " x " & i & " = " & (N * i) & NewLine
next
call ShowMsg(S,"Math Board Of " & N)
end
