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
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
脚本的调用:
script=c:\Math Board.ssf
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
脚本调试器的调用
script debug
脚本的语法定义:
begin
statement;
statement;
end
statement= 条件语句
if (cond)
statement
else
statement
endif
或者
if (cond)
statement
endif
statment= For语句
for (val,开始值,结束值,增量值)
statement;
statement;
next
statement= While语句
while (条件)
statment;
statment;
next
statement=call语句
calll func par,par,par
statement;
statement;
end
statement= 条件语句
if (cond)
statement
else
statement
endif
或者
