我想知道是否有办法在eclipse-pydev中使用键盘快捷键自动修复所有PEP-8问题。谷歌搜索并没有把我带到任何地方。
由于Pydev可以检测到PEP-8问题,是否应该无法自动修复它们?
答案 0 :(得分:14)
你可以用 Ctrl + Shift + F 激活PyDev代码格式化程序(首选项: Window> Preferences&gt ; PyDev>编辑器>代码样式>代码格式化程序 - 您甚至可以让它自动工作。)
尽管如此,内部PyDev代码格式化程序非常保守,并不会完成100%兼容PEP8代码所需的所有转换(尽管它处理更常见的情况),因此,如果它不足以满足您的需求,那么一些选择:
您可以使用autopep8.py,默认情况下也会在最新版本中集成到PyDev中(通过 Window> Preferences> PyDev> Editor> Code Style> Code Formatter>使用autopep8.py进行代码格式化?)
您可以查看PythonTidy(外部工具)......可以按照以下定义使用它:http://bear330.wordpress.com/2007/10/30/using-pythontidy-in-pydev-as-code-formatter/
答案 1 :(得分:4)
我制作了一个脚本,可以在pydev中使用autopep8作为代码格式化程序, 它可以定制,以满足您团队中的编码标准。
如果要使用它,请将此代码保存为pyedit_autopep8.py(需要pyedit_XXXX.py)。您还必须安装python包pep8和autopep8。
接下来,转到eclipse pydev首选项页面(at:window> preferences> pydev> scripting pydev)来指定脚本位置:
现在,为了调用autopep8,你可以在eclipse中编辑python代码时按Ctrl + Shift + F.格式化所选文本也受支持!
