我想知道是否有任何方法可以使用 eclipse-pydev 中的键盘快捷键自动修复所有 PEP-8 问题。谷歌搜索没有让我到任何地方。
既然 Pydev 可以检测到 PEP-8 问题,难道不能自动修复它们吗?
Ctrl您可以使用++手动激活 PyDev 代码格式化程序(首选项位于: Window Shift> Preferences > PyDev > Editor > Code Style > Code Formatter - 请注意,您可以将其配置为在Window > Preferences > PyDev > Editor > Save下自动运行行动)。F
请注意,内部 PyDev 代码格式化程序非常保守,不会执行 100% 兼容的 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,您有一些选择:
您可以使用autopep8.py
orblack
在最新版本中默认集成到 PyDev 中(通过Window > Preferences > PyDev > Editor > Code Style > Code Formatter > Formatter Style? 启用?然后选择 autopep8
or black
)。
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 -格式化程序/
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,并且可以对其进行自定义以满足您团队的编码标准。
如果您想使用它,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(位于:window > preferences > pydev > scripting pydev)以指定脚本位置:
现在,为了调用 autopep8,您只需在 eclipse 中编辑 python 代码时按 Ctrl+Shift+F。还支持格式化所选文本!
