Eclipse 和 Windows 换行符

Eclipse and Windows newlines

提问by Vasu

I had to move my Eclipse workspace from Linux to Windows when my desktop crashed. A week later I copy it back to Linux, code happily, commit to CVS. And alas, windows newlines have polluted many files, so CVS diff dumps the entire file, even when I changed a line or two!

当我的桌面崩溃时，我不得不将我的 Eclipse 工作区从 Linux 移动到 Windows。一周后，我将它复制回 Linux，愉快地编写代码，提交到 CVS。唉，windows 换行符污染了许多文件，所以 CVS diff 会转储整个文件，即使我更改了一两行！

I could cook up a script, but I am wondering if it will mess up my Eclipse project files.

我可以编写一个脚本，但我想知道它是否会弄乱我的 Eclipse 项目文件。

As mentioned hereand here:

正如这里和这里提到的：

Set file encoding to UTF-8and line-endings for new files to Unix, so that text files are saved in a format that is not specific to the Windows OS and most easily shared across heterogeneous developer desktops:

• Navigate to the Workspace preferences (General:Workspace)
• Change the Text File Encoding to UTF-8
• Change the New Text File Line Delimiter to Other and choose Unix from the pick-list

将新文件的文件编码设置UTF-8为 Unix，并将新文件的行尾设置为 Unix，以便文本文件以不特定于 Windows 操作系统的格式保存，并且最容易在异构开发人员桌面之间共享：

• 导航到工作区首选项 (General:Workspace)
• 将文本文件编码更改为 UTF-8
• 将新文本文件行分隔符更改为其他并从选择列表中选择 Unix

• Note: to convert the line endings of an existing file, open the file in Eclipse and choose File : Convert Line Delimiters to : Unix

• 注意：要转换现有文件的行尾，请在 Eclipse 中打开文件并选择 File : Convert Line Delimiters to : Unix

Tip: You can easily convert existing file by selecting then in the Package Explorer, and then going to the menu entry File : Convert Line Delimiters to : Unix

提示：您可以通过在 Package Explorer 中选择 then 来轻松转换现有文件，然后转到菜单项File : Convert Line Delimiters to : Unix

I had the same, eclipse polluted files even with one line change. Solution: Eclipse git settings -> Add Entry: Key: core.autocrlf Values: true

即使更改了一行，我也有相同的 eclipse 污染文件。解决方案：Eclipse git settings -> Add Entry: Key: core.autocrlf Values: true

There is a handy bash utility - dos2unix- which is a DOS/MAC to UNIX text file format converter, that if not already installed on your distro, should be able to be easily installed via a package manager. dos2unix man page

有一个方便的 bash 实用程序——dos2unix它是一个 DOS/MAC 到 UNIX 文本文件格式的转换器，如果你的发行版上还没有安装它，应该能够通过包管理器轻松安装。 dos2unix 手册页

In addition to the Eclipse solutions and the tool mentioned in another answer, consider flip. It can 'flip' either way between normal and Windows linebreaks, and does nice things like preserve the file's timestamp and other stats.

除了 Eclipse 解决方案和另一个答案中提到的工具，请考虑flip。它可以在普通换行符和 Windows 换行符之间以任何一种方式“翻转”，并且可以做一些不错的事情，例如保留文件的时间戳和其他统计信息。

You can use it like this to solve your problem:

您可以像这样使用它来解决您的问题：

find . -type f -not -path './.git/*' -exec flip -u {} \;

(I put in a clause to ignore your .git directory, in case you use git, but since flip ignores binary files by default, you mightn't need this.)

（我添加了一个子句来忽略您的 .git 目录，以防您使用 git，但由于默认情况下 flip 忽略二进制文件，您可能不需要这个。）

You could give it a try. The problem is that Windows inserts a carriage return as well as a line feed when given a new line. Unix-systems just insert a line feed. So the extra carriage return character could be the reason why your eclipse messes up with the newlines.

你可以试一试。问题在于，当给定新行时，Windows 会插入回车符和换行符。Unix 系统只是插入一个换行符。因此，额外的回车符可能是您的日食与换行符混淆的原因。

Grab one or two files from your project and convert them. You could use Notepad++ to do so. Just open the file, go to Format->Convert to Unix (when you are using windows).

从您的项目中获取一两个文件并进行转换。您可以使用 Notepad++ 来执行此操作。只需打开文件，转到“格式”->“转换为 Unix”（使用 Windows 时）。

In Linux just try this on a command line:

在 Linux 中，只需在命令行上试试这个：

sed 's/$'"/`echo \\r`/" yourfile.java > output.java

To recursively remove the carriage returns (\r) from the CVS/* files in all child directories, run the following in a unix shell:

要从\r所有子目录中的 CVS/* 文件中递归删除回车符 ( )，请在 unix shell 中运行以下命令：

find ./ -wholename "\*CVS/[RE]\*" -exec dos2unix -q -o {} \;
