SELECT FOR FORM - Windows package

I have this loop that repeats for every line in an external file. I would suggest the user choose in each pass, although this does not work. I believe the problem is that the GOTO team breaks the loop somehow. Any thoughts on this?

FOR /F %%i IN (%WORKDIR%\grunt-packages.ini) DO (
    CHOICE /C AN /M "Odinstalovat plugin"
    IF %ERRORLEVEL%==1 GOTO UNINSTALL
    IF %ERRORLEVEL%==2 GOTO SKIP

    :UNINSTALL
        ECHO Odstranuji %%i 
        CALL npm uninstall %%i

    :SKIP
        ECHO Preskakuji %%i
)

Your calculation is correct. gotoinside loop cycles will stop the cycle. Therefore, it should be used instead call. However, the first issue with your script is the need for a delayed extension for the variable ERRORLEVEL. Whenever the variables specified in parentheses expand, use the delayed extension to get the last value.

SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
FOR /F %%i IN (%WORKDIR%\grunt-packages.ini) DO (
    CHOICE /C AN /M "Odinstalovat plugin"
    IF !ERRORLEVEL!==1 CALL :UNINSTALL
    IF !ERRORLEVEL!==2 CALL :SKIP
)
ENDLOCAL
GOTO :EOF

:UNINSTALL
    ECHO Odstranuji %%i 
    CALL npm uninstall %%i
    GOTO :EOF

:SKIP
    ECHO Preskakuji %%i
    GOTO :EOF
  • goto for.
