嵌套批次循环 [英] Nested batch for loops

问题描述

以下嵌套for循环使我疯了（在Windows 7）：

The following nested for-loop drives me mad (on Windows 7):

@echo off
SetLocal EnableDelayedExpansion

set TESTDIRS=fast mid slow
set TD=src\test\resources\testsuite

for %%d in (%TESTDIRS%) do (
    set CTD=%TD%\%%d
    echo CTD: !CTD!
        REM Echos the expected path
    echo CTD: %CTD%
        REM Echos nothing -- understandable

    for /R !CTD! %%f in (*.fs) do (echo %%f)
        REM Echos nothing -- why?
    for /R src\test\resources\testsuite\fast %%f in (*.fs) do (echo %%f)
        REM Echos expected files
)

我试过涉及各种解决方案禁用DelayedExpansion，呼叫报表和诸如此类的东西，但我从来没有内环的工作。我知道，我可以通过一个子程序调用替换内环，但有如此的方式，使其与嵌套循环工作。

I tried various solutions involving disabling DelayedExpansion, call-statements and whatnot, but I never got the inner loop working. I know that I could replace the inner loop by a subroutine call, but there gotta be a way to make it work with nested loops.

推荐答案

如果你使用 PUSHD！CTD！和 POPD ，并让 FOR / R 默认使用当前目录？

What if you used pushd !CTD! and popd, and let FOR /R default to using the current directory?
