Nested batch for loops

Question

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         


        

Answer 1

Because nobody has mentioned it, here is the solution using batch subroutines and the CALL command.

@echo off

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

for %%d in (%TESTDIRS%) do call :process_testdir %%d
goto :eof

:process_testdir
set CTD=%TD%\%1
echo CTD: %CTD%
    REM Echos the expected path

for /R %CTD% %%f in (*.fs) do (echo %%f)
    REM Echos as expected

goto :eof

I know GOTO is not very popular, but batch files were originally designed to use labels for control flow. The parenthetized control structure syntax was added later, and this question is an example of where it breaks down. The problem lends itself well to batch subroutines.
