代码行数统计

最近工作不忙,写了个脚本统计代码行数.记录于此方便以后查阅.python版本2.7

 1 # -*- coding: cp936 -*-
 2 import os
 3 
 4 totalLineCounts = 0
 5 fileCounts = 0
 6 
 7 def GetLines(fullFilename):
 8     lineNum = 0
 9     endCommentLine = 0
10     startCommentLine = 0
11     totalBlankLineNum = 0
12     totalCommentLineNum = 0
13     efficientCodesLineNum = 0
14 
15     InCommentArea = 0  #防止重复统计.比如/* */块内包含有//开头的行
16     
17     for line in open(fullFilename).readlines():
18         line = line.strip()   #去除首尾的空格
19         lineNum += 1
20 
21         if InCommentArea:           
22             if line[-2:] == '*/':
23                 InCommentArea = 0   #出注释区
24                 endCommentLine = lineNum
25                 #print ('注释区:%d行-%d行' % (startCommentLine,endCommentLine))
26                 totalCommentLineNum += (endCommentLine - startCommentLine + 1) 
27         else:                
28             if line == '':          #空行
29                 totalBlankLineNum += 1
30             elif line == '//':      #以//开头的注释
31                 totalCommentLineNum += 1
32             elif line[0:2] == '/*':
33                 InCommentArea = 1   #进入注释区
34                 startCommentLine = lineNum
35             else:
36                 efficientCodesLineNum += 1       
37     #print ('空白行数量:%d,注释行数量:%d,有效代码行数量:%d,总行数:%d' % (totalBlankLineNum,totalCommentLineNum,efficientCodesLineNum,lineNum))
38     return [totalBlankLineNum,totalCommentLineNum,efficientCodesLineNum,lineNum]
39

41 exts = ['cpp','h','txt']
42 #key:ext value:[totalBlankLineNum,totalCommentLineNum,efficientCodesLineNum,lineNum]
43 statistic = {'cpp':[0,0,0,0],'h':[0,0,0,0],'txt':[0,0,0,0]}
44 
45 codesDir = 'D:\\SvnCodes\\main_branch\\code\\billing'
46 #codesDir = 'D:\Test\Sub1\sub1.1\sub1.1.1' 
47 if __name__ == '__main__':
48     for curRoot,curSubDirs,curFiles in os.walk(codesDir):
49         #print curRoot,curSubDirs,curFiles
50         for file in curFiles:
51             fileExt = file.split('.')[-1]
52             if fileExt in exts:
53                 fullFilename = curRoot + os.path.sep + file
54                 r = GetLines(fullFilename)
55                 statistic[fileExt][0] += r[0]
56                 statistic[fileExt][1] += r[1]
57                 statistic[fileExt][2] += r[2]
58                 statistic[fileExt][3] += r[3]
59         
60     print '{ext:[blank,comment,efficient,total]}'
61     print statistic
