应用Python写的一个简单的Class代码生成器(3)

然后，只需要将ClassName替换为定义的类名，将定义的变量组合成 变量声明列表、构造函数参数列表、赋值函数列表，替换掉VariableList，DefaultInitializationList，ConstructorParameterList， ParameterInitializationList， AssignmentList。

Python代码只需完成一些 字符串的组合，替换等。

import sys                      # Load the sys module (导入sys模块)
import string

def ReplaceStrings(stringlist, fromString, toString):
    for i in range(0, len(stringlist)):
        s = stringlist[i]
        s = string.replace(s, fromString, toString);
        stringlist[i] = s
        #print stringlist[i]

f = open("template.txt")            # template.txt
templateTextLines = f.readlines()          # Read all lines into a list (读出所有行到一个列表)
f.close()

f = open('declare.txt')#(sys.argv[1])            # Filename on the command line (从命令行读取文件名)
declareLines = f.readlines()          # Read all lines into a list (读出所有行到一个列表)， strip all space and \n
f.close()

    if typeString=="int" or typeString=="float" or typeString=="double" or typeString=="UInt32" or typeString=="Int32" or typeString == "Float32": # 可自行增加
        constructorParameterListString += typeString + " _" + nameString + ", " #基本类型，采用传值的方式
