【Python自动化】编程控制类型变量顺序化

比如：

#ifndef MSGTYPE_H
#define MSGTYPE_H

// login
const short MSG_LOGIN = 8;

// register
const short MSG_REGIS = 22;

// send message to friend
const short MSG_SENDTOFRIEND = 2;

// send message to group
const short MSG_SENDTOGROUP = 3;

// add friend
const short MSG_ADDFRIEND = 4;
const short MSG_ADDFRIEND_WAIT = 9;
const short MSG_ADDFRIEND_NONAME = 6;

// initial client's friend list
const short MSG_INITFRIEND_ONLINE = 7;
const short MSG_INITFRIEND_OFFLINE = 88;
const short MSG_INITGROUP = 11;

// 当本地没有检测到好友等初始化数据，那么服务器给予相关数据
const short MSG_BUILDGROUP = 10;

// invite member
const short MSG_GROUPINVIMEM = 12;
const short MSG_GROUPINVIMEM_WAIT = 18;
const short MSG_GROUPINVIMEM_SUCC = 13;
const short MSG_GROUPINVIMEM_FAIL = 14;
const short MSG_GROUPINVIMEM_NONAME = 15;

// request enter group
const short MSG_REQENTERGROUP = 16;
const short MSG_REQENTERGROUP_WAIT = 17;
const short MSG_REQENTERGROUP_SUCC = 1;
const short MSG_REQENTERGROUP_FAIL = 19;
const short MSG_REQENTERGROUP_NONAME = 20;

const short MSG_DOWNLOAD_FILE = 21;
const short MSG_UPLOAD_FILE = 64;
//////////////////////////////
/////////reload控制信息//////////////
const short MSG_RELOAD_FILE = 23;
//////////////////////////////
const short MSG_DELETE_FILE = 24;

const short MSG_ECHO = 25;
const short MSG_OK = 26;
const short MSG_ERROR = 27;
const short MSG_NOT_CLEAR = 28;

#endif // MSGTYPE_H

有这么一个文件，这是一个例子。

因为编程过程中间又插入一个消息类型，那么此时又要修改后面的数据顺序化，非常繁琐，

python实现自动顺序化：

1 #!/usr/bin/python
2
3 import re
4 import sys
5 import os
6
7 def SerializeNumber():
8     fd = open(sys.argv[1], 'r')
9     fd_1 = open("swap", "w")
10     lines = fd.readlines()
11     ls = []
12     i = 0
13     j = 0
14     print lines
15     for line in lines:
16         if re.match("const short", line):
17             result = re.match("const short \w+_\w+_?\w* ?= ?", line).group();
18             lines[i] = result + str(j) + ";"
19             print lines[i]
20             j+=1
21         ls.append(lines[i].strip('\n') + '\n')
22         i += 1
23
24     fd_1.writelines(ls)
25     fd.close()
26     fd_1.close()
27     os.remove(sys.argv[1])
28     os.rename("swap", sys.argv[1])
29
30
31 if __name__ == '__main__':
32     SerializeNumber()

上面通过匹配每个消息，进行值顺序化，代码非常简单。

python是自动化的利器。
