Vim 写入时覆盖文件名 [英] Vim overwrites filename when writing

问题描述

假设我有一个名为 FooBar.java 的文件.当我使用

Let's say I have a file called FooBar.java. When I open the file in a powershell window with

>vim foobar.java

> vim foobar.java

编辑后写入文件，文件重命名为FooBar.java ->foob​​ar.java.

and write the file after editing it, the file gets renamed FooBar.java -> foobar.java.

如果我用

>vim FOOBAR.java

> vim FOOBAR.java

它被重命名为 FooBar.java ->FOOBAR.java.

it gets renamed FooBar.java -> FOOBAR.java.

因此，当我使用 powershell 命令打开文件时，Vim 将名称更改为区分大小写.这对我来说是不受欢迎的行为，在我全新安装操作系统(Windows 10)之前，我没有遇到过这个问题.我正在使用与以前完全相同的 .vimrc.这是一个巨大的痛苦，因为 java 的文件名区分大小写.

So Vim changes the name to be case sensitive to how I spelled it when I opened the file with a powershell command. This is undesired behaviour for me, and I did not have this problem earlier, before I did a clean install of my OS (Windows 10). I am using the exact same .vimrc as before. This is a huge pain in the ass since java is case sensitive with it's filenames.

然而，它似乎只发生在 .java 文件中.对于 .cpp 或 .txt 或 .csv 文件，无论我如何键入，文件的大小写都保持不变.

However, it seems to only happen with .java files. With .cpp or .txt or .csv files, the capitalization of the file remains the same regardless of how I type it.

我的问题分为两部分:

1. 为什么 Vim 突然执行此操作，而之前没有使用相同的 .vimrc 执行此操作?
2. 如何永久禁用此行为，最好使用 .vimrc 行?

Vim 以小写形式保存文件

这是我的 .vimrc 的内容:

Here are the contents of my .vimrc:

"Created for Vim version 8.2

set clipboard+=unnamed

set backspace=indent,eol,start

set undodir=~\vimfiles\undodir

推荐答案

您可以通过以下方式解决此问题:

You can fix this with:

set backupcopy=yes

将此选项设置为默认值后，Vim 最终会通过重命名原始文件来备份它，然后创建一个与您正在编辑的文件同名的新文件.但是在文件名不区分大小写的文件系统(通常是 Windows)中，如果您通过不同大小写的名称来引用文件，Vim 最终可能会创建具有不同大小写的新文件.

With this option set to its default value, Vim ends up backing up the original file by renaming it and then creating a new file with the same name as the one you're editing. But in filesystems with case-insensitive filenames (typically, Windows) and if you refer to files by a name with a different case, Vim might end up creating the new file with the different case.

使用 backupcopy=yes 将使 Vim 将备份创建为新副本(而不是重命名原始文件)，然后覆盖原始文件.执行该操作时，文件名的大小写不会改变，因为 Vim 并不是真正创建新文件，而是写入现有文件，因此文件系统将保留原始名称(以及原始文件的任何属性).)

Using backupcopy=yes will have Vim create the backup as a new copy (instead of a rename of the original file) and then it will overwrite the original file. When that operation is performed, the case of the filename won't change, since Vim isn't really creating a new file but writing to an existing one, so the filesystem will preserve the original name (and any attributes the of the original file.)
