主要的python脚本文件LineCount.py的内容如下：
import sys;
import os;
class LineCount:
def trim(self,docstring):
if not docstring:
return ''
lines = docstring.expandtabs().splitlines()
indent = sys.maxint
for line in lines[1:]:
stripped = line.lstrip()
if stripped:
indent = min(indent, len(line) - len(stripped))
trimmed = [lines[0].strip()]
if indent < sys.maxint:
for line in lines[1:]:
trimmed.append(line[indent:].rstrip())
while trimmed and not trimmed[-1]:
trimmed.pop()
while trimmed and not trimmed[0]:
trimmed.pop(0)
return '\n'.join(trimmed)
def FileLineCount(self,filename):
(filepath,tempfilename) = os.path.split(filename);
(shotname,extension) = os.path.splitext(tempfilename);
if extension == '.txt' or extension == '.hol' : # file type
file = open(filename,'r');
self.sourceFileCount += 1;
allLines = file.readlines();
file.close();
lineCount =0;
commentCount = 0;
blankCount = 0;
codeCount = 0;
for eachLine in allLines:
if eachLine != " " :
eachLine = eachLine.replace(" ",""); #remove space
eachLine = self.trim(eachLine); #remove tabIndent
if eachLine.find('--') == 0 : #LINECOMMENT
commentCount += 1;
else :
if eachLine == "":
blankCount += 1;
else :
codeCount += 1;
lineCount = lineCount + 1;
self.all += lineCount;
self.allComment += commentCount;
self.allBlank += blankCount;
self.allSource += codeCount;
print filename;
print ' Total :',lineCount ;
print ' Comment :',commentCount;
print ' Blank :',blankCount;
print ' Source :',codeCount;
def CalulateCodeCount(self,filename):
if os.path.isdir(filename) :
if not filename.endswith('\\'):
filename += '\\';
for file in os.listdir(filename):
if os.path.isdir(filename + file):
self.CalulateCodeCount(filename + file);
else:
self.FileLineCount(filename + file);
else:
self.FileLineCount(filename);
# Open File
def __init__(self):
self.all = 0;
self.allComment =0;
self.allBlank = 0;
self.allSource = 0;
self.sourceFileCount = 0;
filename = raw_input('Enter file name: ');
self.CalulateCodeCount(filename);
if self.sourceFileCount == 0 :
print 'No Code File';
pass;
print '\n';
print '***************** All Files **********************';
print ' Files :',self.sourceFileCount;
print ' Total :',self.all;
print ' Comment :',self.allComment;
print ' Blank :',self.allBlank;
print ' Source :',self.allSource;
print '****************************************************';
myLineCount = LineCount();
可以看到extension == '.txt' or extension == '.hol'这句是判断文件的后缀，来确定是否要计算代码行数。
if eachLine.find('--') == 0 :这句来判断当前行是不是单行注释（我们的这门语言不支持块注释）。
为了能在其他机器上运行，使用了py2exe来把python脚本生成可执行的exe，setup.py脚本内容如下：
from distutils.core import setup
import py2exe
setup(
version = "0.0.1",
description = "LineCount",
name = "LineCount",
console = ["LineCount.py"],
)
不过生成exe后程序臃肿很多，有3M多。
感觉使用python确实是件很惬意的事。
