For now, I'll add the msys2 path and the msystem var to the bat file

Octave.vbs use the "octave-gui.exe --no-gui" and it is working well thanks to that correct path and any other declared variables.

But, i can not use octave.vbs when i want to execute it from an own C program as a childprocess with pipe interface. Octave.vbs will start octave-gui.exe as a background process in a new cmd window (then exit), so that my own C program does not have any pipe connection to the octave-gui.exe.

If i use the "octave.bat --no-gui" it is better because the bat file will run octave-gui.exe in the same cmd and it will be the same childprocess. In this case the pipe connection is fine and works well.

In the past i never used any plots and figure printing and the octave-cli.exe was enough for my tasks. But now i need a correct qt graphics for plots in command-line octave, too.

I think in the future a fixed octave.bat (with using octave-gui.exe --no-gui) should be better to a general executing method in MS Windows than the octave.vbs script.

One of the reasons for using octave-cli was that in windows, octave-gui detaches itself when run, so any scripts - ie: configure of a package calling octave, will fail as it tehn doesnt get anything from any commands tnat may run via eval etc

I dont believe vbs will run via command line in msys2, and mkoctfile etc doesnt look for it

I beleieve the changes for the bat file etc where done on https://savannah.gnu.org/bugs/?53938

Why do we need vbs and bat versions of the wrapper script?  Isn't one sufficient?

Thank you for the bug report. I do not personally have access to Windows to test any of this, but it was my understanding that 'octave-gui --no-gui' did not work reliably on Windows. If it does work reliably now, that is news to me, and possibly to others who do use Octave on Windows all the time.

If this is reliable, then maybe the defaults should be changed so that 'octave' does run the 'octave-gui' executable with either of the '--gui' or '--no-gui' options. And maybe a new 'octave-cli.bat' script should be added to call 'octave-cli' with the necessary environment variables.

This probably needs confirmation and investigation by those who care about Octave on Windows.

In a first look, it seems to me that octave.bat and octave.vbs script is different. Pls compare it and fix octave.bat!

When i want to use octave.vbs --no-gui, everything is fine, qt graphics is working well, and all of executable files from usr/bin example: cat, ssh ... are working in octave.

But when i want to use the octave.bat --no-gui, qt graphics is missing and all contents from usr/bin are missing, too.

Pls fix it as soon as possible. I fixed that bugs in the octave.bat for my own usage, but it is in the attached files feel free to use it. I have been set usr/bin into path, i declared the correct MSYSTEM variable (MINGW64 or MINGW32) and i am using now octave-gui.exe --no-gui instead of ocatve-cli.exe and now it works well.

It is important to me that i could use qt graphics in command-line mode also. (Octave.vbs use the same way with usage of octave-gui.exe --no-gui)
