PyChecker使用指南

转载&＃xff1a;http://blog.csdn.net/thoughtwise/article/details/5719455

简介

PyChecker是一个对Python源代码进行语法检查的工具。

主页&＃xff1a;http://pychecker.sourceforge.net

PyChecker is a static analysis tool for finding bugs in Python source code. It finds problems that are typically caught by a compiler for less dynamic languages, like C and C&＃43;&＃43;. It is similar to lint.

目前最新版本是2008-08-18 更新的pychecker-0.8.18。

安装

前提&＃xff1a;本地安装好Python2.x&＃xff0c; 推荐2.6版本&＃xff0c;虽然2.7版本也发布了。3.0版差异太大&＃xff0c;相当于全新版本&＃xff0c;不保证兼容性&＃xff0c;不推荐使用。

最好将IPython也一并安装了。

下载地址&＃xff1a;http://sourceforge.net/projects/pychecker/

从网页上下载pychecker-0.8.18.tar.gz&＃xff0c;解压。

然后在pychecker-0.8.18目录(其下有setup.py脚本)&＃xff0c; 执行命令行python setup.py install 执行安装。这也是在Windows下python软件的通用安装方式。

使用

安装好后&＃xff0c;试试在pychecker-0.8.18目录执行命令行pychecker setup.py&＃xff0c;检查setup.py的语法

E:/pychecker-0.8.18>pychecker setup.py

E:/pychecker-0.8.18>C:/Python26/python.exe C:/Python26/Lib/site-packages/pychecker/checker.py se
tup.py
Processing module setup (setup.py)...

Warnings...

C:/Python26/lib/distutils/command/bdist_wininst.py:271: Statement appears to have no effect

C:/Python26/lib/distutils/command/install_scripts.py:53: No class attribute (dry_run) found

19 errors suppressed, use -#/--limit to increase the number of errors displayed

这里pychecker 是个bat脚本&＃xff0c;实际执行的是C:/Python26/python.exe C:/Python26/Lib/site-packages/pychecker/checker.py 。

这里检查结果将setup.py依赖的文件中语法错误或告警也检查出来了。

如果只想检查setup.py自身的语法&＃xff0c;可以用--only参数

E:/pychecker-0.8.18>pychecker --only setup.py

E:/pychecker-0.8.18>C:/Python26/python.exe C:/Python26/Lib/site-packages/pychecker/checker.py --only setup.py
Processing module setup (setup.py)...

Warnings...

None

更多的参数&＃xff0c;可以使用pychecker --help查看
