批次：串连SETLOCAL EnableDelayedExpansion外任意两个字符串 [英] Batch: Concatenate two arbitrary strings outside SETLOCAL EnableDelayedExpansion
问题描述
我需要连接两个字符串变量，并将结果放回第一个变量。这两个字符串可以包含的任何的任意字符，像换行，感叹号等。
主要脚本延迟扩展运行的停用的，所以我必须使用的 SETLOCAL EnableDelayedExpansion 的实际串联。我只是不知道如何将结果返回到本地，进入全局变量。
我想避免使用临时文件。
我想允许的批处理文件，当地块外延迟扩展。
感谢。

@Jeb结果
我试着用你的code内联，而不是在一个功能，它的工作。结果
然后我试图把它在一个for循环中，并把它弄坏了。结果
从循环=作品函数调用。结果
Inline是一个循环=我没有工作。结果
我现在不需要该功能。这只是一个观察。结果
谢谢你。

好吧，这看起来有点复杂，而且在许多情况下，它可以与其他伎俩来解决。结果
如果你知道，你会从EnableDelayed到DisableDelayed切换回来，你一定不使用任何一个LF FOR-回报将工作了。

I need to concatenate two string variables and place the result back in the first variable. These two strings can contain any arbitrary characters, like newline, exclamation, etc.
The main script runs with delayed expansion disabled, so I have to use SETLOCAL EnableDelayedExpansion for actual concatenation. I just don't know how to get the result back out of the local and into the global variable.
I would like to avoid using temporary files.
I wish batch files allowed delayed expansion outside of the local block.
Thanks.
EDIT :
@Jeb
I tried using your code inline, instead of in a function, and it worked.
Then I tried putting it in a FOR loop, and that broke it.
Function call from a loop = works.
Inline is a loop = didn't work for me.
I don't need that functionality right now. This is just an observation.
Thanks.
@echo off
REM Changed from function call to inline implementation

pause
goto :eof
Like I said in your other question: Batch: Returning a value from a SETLOCAL EnableDelayedExpansion
Just follow the link for a "perfect" solution
Or I can paste the code here
rem ** Preparing CR and LF for later use
for /f %%a in ('copy /Z "%~dpf0" nul') do set "CR=%%a"
set LF=^
rem TWO Empty lines are neccessary
Then at the start of your function, to detect if delayedExpansion is OFF or ON
setlocal
set "NotDelayedFlag=!"
setlocal EnableDelayedExpansion
And at the end of your function, to return the value
rem ** Prepare for return
set "var=!var:%%=%%~2!"
set "var=!var:"=%%~3!"
for %%a in ("!LF!") do set "var=!var:%%~a=%%~L!"
for %%a in ("!CR!") do set "var=!var:%%~a=%%~4!"
rem ** It is neccessary to use two IF's, else the %var% expansion doesn't work as expected
if not defined NotDelayedFlag set "var=!var:^=^^^^!"
if not defined NotDelayedFlag set "var=%var:!=^^^!%" !
set "replace=%% """ !CR!!CR!"
for %%L in ("!LF!") do (
for /F "tokens=1,2,3" %%2 in ("!replace!") DO (
ENDLOCAL
ENDLOCAL
set "%~1=%var%" !
@echo off
goto :eof
)
)
EDIT: A little bit shorter variation
Ok, this looks a little bit complicated, and in many cases it can be solved with an other trick.
If you know, that you will switch back from an EnableDelayed to DisableDelayed and you are sure not using any LF a FOR-RETURN will work too.
@echo off
setlocal
call :myTest result
set result
goto :eof
:myTest
setlocal EnableDelayedExpansion
rem ... do something here
set "value=^!_&_%%_|_>"
echo --
for /f ^"eol^=^
^ delims^=^" %%a in ("!value!") do (
endlocal
set "%~1=%%a"
goto :eof
)
The splitting of the for /f ^"eol^=^.... is only for disabling the eol character.
