Call Waiting Spinner Via Arguments In Batch Script - windows

Question

I wanted to call waiting spinner on my batch script like this is my code:
#echo off
::-----------------------------Waiting-Spinner-------------------------------
:spinner
set mSpinner=%mSpinner%.
if %mSpinner%'==....' (set mSpinner=.)
cls
::----------------------------Subdomain-Script-------------------------------
echo Enumerating Subdomains From Script1 %mSpinner%
python2 enumsubdomain.py google.com > google.txt
SLEEP 1
goto spinner
echo Enumerating Subdomains From Script2 %mSpinner%
python2 enumsubdomain2.py yahoo.com > yahoo.txt
SLEEP 1
goto spinner
#pause
And this spinner text output should be something like this:
Enumerating Subdomains From Script1 ...<Here this dot will be animated]
Enumerating Subdomains From Script2 ...<Here this dot will be animated]
But it only outputs first line(Script1) and the 2nd script stops and doesn't outputs the 2nd line as well, i guess it's because of goto line in batch script and i have no idea what can be done here to make it work!

Answer 1

After clarification in your comment, you'd probably want something like this.
We start the commands in separate windows with new window titles per window, then we use tasklist to determine of either are still running. So both results will be echo if both run, or only one will be echod if only one runs.
#echo off
set done1=1
set done2=1
start "enum1" /min cmd.exe /C ^(python2 enumsubdomain.py google.com ^> google.txt^)
start "enum2" /min cmd.exe /C ^(python2 enumsubdomain2.py yahoo.com ^> yahoo.txt^)
:spinner
set mSpinner=%mSpinner%.
if "%mSpinner%"=="...." (set mSpinner=.)
cls
(tasklist /FI "WINDOWTITLE eq enum1" | findstr /i "cmd")>nul && echo Enumerating Subdomains From Script1 %mSpinner% || set done1=0
(tasklist /FI "WINDOWTITLE eq enum2" | findstr /i "cmd")>nul && echo Enumerating Subdomains From Script2 %mSpinner% || set done2=0
if %done1% equ 0 if %done2% equ 0 goto :eof
(sleep 1)>nul
goto :spinner

You want to use the spinner several times, so using a subroutine for the spinner is a good idea.
The main problem is: batch waits for a command to end before continuing with the next one, so you can't include the python command into the loop. Solution: start the command as an independent process and then start the "spinning loop". Break it, when the independent process does not exist anymore.
Here the subprocess :spinner takes a string as parameter (the message), making it flexible.
Instead of clearing the screen (cls) for each iteration of the loop, I took a different approach: overwriting the line over and over (less flickering and keeping the previous screen intact)
#echo off
setlocal EnableDelayedExpansion
REM create a CariageReturn:
for /f %%a in ('copy /Z "%~dpf0" nul') do set "CR=%%a"
cls
start /min "MySpinnerProcess" cmd /c "timeout 8 >google.txt"
call :spinner "Enumerating Subdomains From Script1"
start /min "MySpinnerProcess" cmd /c "timeout 5 >yahoo.txt"
call :spinner "Enumerating Subdomains From Script2"
echo finished.
goto :eof
:spinner
tasklist /fi "WindowTitle eq MySpinnerProcess" 2>nul | findstr /bilc:"cmd.exe" >nul || (
echo %~1 done.
goto :eof
)
set "mspinner=%mspinner%."
if %mspinner% == .... set "mspinner=."
<nul set /p ".=%~1 %mspinner% !CR!"
timeout 1 >nul
goto :spinner
For completeness my script for running the two scripts simultaneously. (very similar to Gerhard's solution, but keeping two spinners) (in my defense: I already had it ready when I asked you if you want them one after the other or simultaneously, but I just had to spend the sunny Sunday Afternoon outside)
#echo off
setlocal
::---------Waiting-Spinner---------
start /min "MyPhytonProcess1" cmd /c "timeout 8 >google.txt"
start /min "MyPhytonProcess2" cmd /c "timeout 5 >yahoo.txt"
:spinner
set mSpinner1=%mSpinner1%.
set mSpinner2=%mSpinner2%.
if %mSpinner1%==.... (set mSpinner1=.)
if %mSpinner2%==.... (set mSpinner2=.)
cls
::----------------------------Subdomain-Script-------------------------------
echo Enumerating Subdomains From Script1 %mSpinner1%
echo Enumerating Subdomains From Script2 %mSpinner2%
if "%mSpinner1%%mSpinner2%" == "Done.Done." goto :done
tasklist /FI "WindowTitle eq MyPhytonProcess1" 2>nul |find "cmd.exe" >nul || set "mSpinner1=Done"
tasklist /FI "WindowTitle eq MyPhytonProcess2" 2>nul |find "cmd.exe" >nul || set "mSpinner2=Done"
timeout 1 >nul
goto :spinner
:done
echo finished.
#pause
