1. 比对两个字符串差异.
# vi diff.py
#!/usr/bin/env python
import difflib
text1 = """text1:
This mudule provides classes and fuctions for comparing sequences.
including HTML and context and unified diffs.
difflib document v7.4
add string
"""
text1_lines = text1.splitlines()
text2 = """text2:
This mudule provides classes and fuctions for Comparing sequences.
including HTML and context and unified diffs.
difflib document v7.5
"""
text2_lines = text2.splitlines()
#d = difflib.Differ()
#diff = d.compare(text1_lines, text2_lines)
#print "\n".join(list(diff))
d = difflib.HtmlDiff()
print d.make_file(text1_lines, text2_lines)
运行脚本并重定向为一个html静态页面
# chmod 755 diff.py
# ./diff.py > diff.html
浏览器打开该页面
如图:
2. 比对两个配置文件的差异.
# vi diff02.py
#!/usr/bin/env python
import difflib
import sys
try:
textfile1 = sys.argv[1]
textfile2 = sys.argv[2]
except Exception, e:
print "Error: " + str(e)
print "Usage: %s filename1 filename2" %sys.argv[0]
sys.exit()
def readfile(filename):
try:
with open(filename, "rb") as fileHandle:
text = fileHandle.read().splitlines()
return text
except IOError as error:
print ("Read file Error:" + str(error))
sys.exit()
if not textfile1 or not textfile2:
print "Usage: %s filename1 filename2" %sys.argv[0]
sys.exit()
text1_lines = readfile(textfile1)
text2_lines = readfile(textfile2)
d = difflib.HtmlDiff()
print d.make_file(text1_lines, text2_lines)
# ./diff02.py nginx.conf.v1 nginx.conf.v2 >diff02.html
