强制执行“空格"或“标签"仅在python文件中? [英] Enforce "spaces" or "tabs" only in python files?

问题描述

在Python中，是否有一种手段可以强制每个文件使用空格或制表符缩进?

In Python, is there a mean to enforce the use of spaces or tabs indentation with a per file basis ?

好吧，也许强制执行"太强了，更像是建议".

Well, perhaps "enforce" is too strong, more like a "recommendation".

我一直在接收带有混合缩进的补丁文件，这很烦人……(至少可以说)Python本身可以告诉您什么时候出现问题，但是我正在搜索某个东西来在编辑器级别执行此操作，就像它存在一样为字符集.

I keep receiving patch files with mixed indentation and this is annoying... (to say the least) Python itself can tell when there is a problem, but I am searching something to do that at the editor level, like it exists for the charset.

好的，我的问题还不清楚，我问这个问题是因为我一直在收到可以想象到的选项卡/空格组合中的更正和补丁.我正在使用Mercurial作为DVCS，也许在此级别上存在某些内容?

Edit : Ok, my question wasn't clear, I am asking this because I keep receiving corrections and patches in any mix of tab/space you can imagine. I am using Mercurial as a DVCS, perhaps something exists at this level ?

推荐答案

蒂姆·彼得斯(Tim Peters)编写了一个漂亮的脚本，名为此处可用，但请先检查您的发行版-可能已捆绑在示例"或工具"目录中. (在最新的LTS Ubuntu上，它是由python2.7-examples软件包提供的.)

Tim Peters has written a nifty script called reindent.py which converts .py files to use 4-space indents and no tabs. It is available here, but check your distribution first -- it may have come bundled in an Examples or Tools directory. (On the latest LTS Ubuntu, it is provided by the python2.7-examples package.)

如果您可以设置Mercurial挂钩，则应该能够通过reindent.py运行所有文件.

If you can set up a Mercurial hook you should be able to run all files through reindent.py.

顺便说一句，如果您使用的是UNIX，则您的系统可能还具有expand(和unexpand)命令，该命令会将所有制表符转换为空格(并将空格转换为制表符).但是，在这种情况下，我认为reindent.py是正确的工具.

By the way, if you are using unix, then your system may also have the expand (and unexpand) command, which convert all tabs to spaces (and spaces to tabs). However, in this case, I think reindent.py is the right tool.
