juggle添加c#版本

此前做过一个c++版的网络层dsl：.html

现在给这个dsl加入c#的支持，并且对代码的结构做了优化,将语法解析和代码生成做了解耦

语法解析部分

class func(object):def __init__(self):self.keyworld = ''self.func = []self.argvtuple = Nonedef clear(self):self.keyworld = ''self.func = []self.argvtuple = Nonedef push(self, ch):if ch == ' ' or ch == '\0':self.keyworld = deleteNoneSpacelstrip(self.keyworld)if self.keyworld != '':if self.argvtuple is None:self.func.append(deleteNoneSpacelstrip(self.keyworld))else:if self.keyworld in ['table', 'array', 'int', 'string', 'float', 'bool']:self.argvtuple.append(deleteNoneSpacelstrip(self.keyworld))self.keyworld = ''return Falseif ch == ',':if self.keyworld != '' and self.keyworld in ['table', 'array', 'int', 'string', 'float', 'bool']:self.argvtuple.append(deleteNoneSpacelstrip(self.keyworld))self.keyworld = ''return Falseif ch == '(':self.keyworld = deleteNoneSpacelstrip(self.keyworld)if self.keyworld != '':self.func.append(deleteNoneSpacelstrip(self.keyworld))self.argvtuple = []self.keyworld = ''return Falseif ch == ')':if self.keyworld != '' and self.keyworld in ['table', 'array', 'int', 'string', 'float', 'bool']:self.argvtuple.append(deleteNoneSpacelstrip(self.keyworld))if self.argvtuple is None:self.func.append([])else:self.func.append(self.argvtuple)self.keyworld = ''return Falseif ch == ';':return Trueself.keyworld += chreturn Falseclass module(object):def __init__(self):self.keyworld = ''self.name = ''self.module = []self.machine = Nonedef push(self, ch):if ch == '}':self.machine = Nonereturn Trueif self.machine is not None:if self.machine.push(ch):self.module.append(self.machine.func)self.machine.clear()else:if ch == '{':self.name = deleteNoneSpacelstrip(self.keyworld)self.keyworld = ''self.machine = func()return Falseself.keyworld += chreturn Falseclass statemachine(object):def __init__(self):self.keyworld = ''self.module = {}self.machine = Nonedef push(self, ch):if self.machine is not None:if self.machine.push(ch):if isinstance(self.machine, module):self.module[self.machine.name] = self.machine.moduleself.machine = Noneelse:if ch == ' ' or ch == '\0':if deleteNoneSpacelstrip(self.keyworld) == 'module':self.machine = module()self.keyworld = ''else:self.keyworld += chdef getmodule(self):return self.moduledef syntaxanalysis(self, genfilestr):for str in genfilestr:for ch in str:self.push(ch)

解析采用状态机机制，逐字符读取代码在读取到关键字符则跳转状态，并且保持读取到的关键字。

读取的关键字采用table方式保持

module：[funcinfo, ...]

在代码生成部分，按解析获取的语法table生成module和caller代码，分别是事件的响应和调用端。

def gencaller(module_name, funcs):code = "/*this caller file is codegen by juggle*/\n"code += "using System;\n"code += "using System.Collections;\n"code += "using System.IO;\n"code += "using MsgPack;\n"code += "using MsgPack.Serialization;\n\n"code += "namespace caller\n"code += "{\n"code += "    public class " + module_name + " : Icaller \n"code += "    {\n"code += "        public " + module_name + "(Ichannel _ch) : base(_ch)\n"code += "        {\n"code += "            module_name = \"" + module_name + "\";\n"code += "        }\n\n"for i in funcs:code += "        public void " + i[1] + "("count = 0for item in i[2]:code += tools.gentypetocsharp(item) + " argv" + str(count)count = count + 1if count < len(i[2]):code += ","code += ")\n"code += "        {\n"code += "            ArrayList _argv = new ArrayList();\n"for n in range(len(i[2])):code += "            _argv.Add(argv" + str(n) + ");\n"code += "            call_module_method(\"" + i[1] + "\", _argv);\n"code += "        }\n\n"code += "    }\n"code += "}\n"return code

def genmodule(module_name, funcs):code = "/*this module file is codegen by juggle*/\n"code += "using System;\n"code += "using System.Collections;\n\n"code += "namespace module\n{\n"code += "    public class " + module_name + " : Imodule \n    {\n"code += "        public " + module_name + "()\n        {\n"code += "            module_name = \"" + module_name + "\";\n"code += "        }\n\n"for i in funcs:code += "        public abstract void " + i[1] + "("count = 0for item in i[2]:code += tools.gentypetocsharp(item) + " argv" + str(count)count = count + 1code += ");\n\n"code += "    }\n"code += "}\n"return code

和juggle的上个版本不同，为了简洁的用于开发游戏服务器，这个版本删除了同步调用功能，只保留异步调用，对同步调用感兴趣的 可以阅读darckforce里面的代码:

这个版本的代码地址在:

我将基于这个版本的juggle开发一个开源的游戏服务器框架，欢迎大家在论坛或博客给我留言提出意见
