Passing around multi-line strings
提问by chief7
I'm trying to create a batch file which passes around a string with line feeds in it but its not working out. The continuation of the string is executed as a new command.
我正在尝试创建一个批处理文件，它传递一个带有换行符的字符串，但它不起作用。字符串的延续作为新命令执行。
Is there anyway to encode a line feed or make this work?
无论如何编码换行符或使这项工作？

You can create directly multiline strings with the caret (one empty line is required).
您可以使用插入符号直接创建多行字符串（需要一个空行）。
setlocal EnableDelayedExpansion
set multiLine=This is a ^
multiline text^
line3
echo !multiLine!
Or you can create first a newline character.
或者您可以先创建一个换行符。
setlocal EnableDelayedExpansion
set LF=^
rem Two empty lines are required
set multiLine=This is a!LF!multiline text!LF!line3
echo !multiLine!
An explanation how this works can be found at Explain how dos-batch newline variable hack works
可以在解释 dos-batch 换行变量 hack 的工作原理中找到有关其工作原理的解释

Expansion to jeb answer, Adding !LF!^ to each line would be easy
扩展到jeb answer，将 !LF!^ 添加到每一行会很容易
setlocal EnableDelayedExpansion
set LF=^
set multiLine=This is a!LF!^
multiline text!LF!^
line3
echo !multiLine!
