c++ - c++自动生成函数签名

Question

我在生成函数方面遇到了问题，它变得非常乏味，复制和粘贴我有大约 400 个函数。自动生成它们的最简单方法是什么？
我希望只输入 IController.h，其余的会自动填充，如果有人能指导我做这样的事情，那就太好了。

我有 4 个单独的文件。

IController.h
Controller.h
Controller.cpp
MockController.h

例如，在 IController.h 文件中，我有一个名为 display 的函数

class IController
{
 public:
 virtual void display(Gui* gui) = 0; 
}

Controller 类将从 IController 继承，关键字 virtual 被移除，=0。

class Controller : public IController
{
  public:
  void display(Gui* gui);
}

Controller.cpp 将包含定义

void Controller::display(Gui* gui)
{

}

最后 MockController.h 将包含以下内容

class MockController : public IController
{
 public:
  MOCK_METHOD1(display, void(Gui* gui));
};

我花了几天时间才弄明白，希望这对我设法使用下面显示的脚本解决上述问题的人有所帮助。 gmock_gen.py 目前不适用于 python 3.7.2，我安装了 2.7.13，下面的脚本可以工作。

用户只需要为第一个接口(interface)类生成代码，所有其他文件都是自动生成的。

import os

#read contents of IController.h
filename = "IController.h"
file = open(filename,"r")

#variables
flag = False
classheader = ""
mockheader = ""
classbody = None
header = []
classitems = []

#read each line in the file
for line in file:
    # if the class name has been found 
    if(filename[:-2] in line):
        flag = True
    # save all data before the calss name
    if flag == False:
        header.append(line)
    #
    if filename[:-2] in line:
        flag = True
        classname = filename[1:-2]
        line = line.replace("class ", "public ")
        classbody = "class " + classname + " : " + line

    # remove virtual = 0
    if "virtual" in line:
        line = line.replace("virtual","")
        line = line.replace(" = 0","")
        classitems.append(line)

classbody += "\n"
classbody += "{\n"
classbody += "  public:\n"

for x in classitems:
     classbody += x 
     classbody + "\n"

classbody += "};"

for x in header:
    classheader += x

classheader += "#include " + "\""  + filename + "\"" + "\n\n"
mockheader += classheader
classheader += classbody

#create controller.h file
f = open(filename[1:], "w")
f.write(classheader)

cppbody = ""

for x in classitems:
    temp = x.split(" ", 2)
    temp2 = temp[1] + " " + filename[1:-2] + "::" + temp[2].replace(";","{\n\n\n}\n")
    cppbody += temp2 

#create controller.cpp file
cppfilename = filename[1:-2] + ".cpp"
f = open(cppfilename,"w")
f.write(mockheader)
f.write(cppbody)


mocktemp = "Temp" + filename[1:]
mockfilename = "Mock" + filename[1:]

input = "python gmock_gen.py " + filename
os.system(input + " > " + mocktemp)

#create MockIController.h
with open(mocktemp) as f:
    with open(mockfilename, "w") as f1:
        f1.write(mockheader)        
        for line in f:
            f1.write(line)
