python实例31[解析buildlog]

简单地解析VisualStudio的buildlog：（有的时候log文件太长，但是我们只是关心warning和error， 通过该程序可以直接得到所有的warning和error的行）

import re

warninglist = []
warninglist.append("warning C\d{4}")

errorlist = []
errorlist.append("error LNK\d{4}")
errorlist.append("error C\d{4}")

def Parse(logfile, regexlist):
resultlines = []
with open(logfile, "r") as log:
for line in log:
for regex in regexlist:
m = re.search(regex, line)
if m:
resultlines.append(line)
return resultlines

def ParseWarning(logfile):
warnings = []
warnings = Parse(logfile, warninglist)
return warnings

def ParseError(logfile):
errors = []
errors = Parse(logfile, errorlist)
return errors

ws = ParseWarning("buildlog.txt")
print( "warnings:" + str(len(ws)))
for w in ws:
print (w)
es = ParseError("buildlog.txt")
print( "errors:" + str(len(es)))
for e in es:
print(e)

继续改进中。。。

完！
