The demo does not work as the demo image shows

[aqasoft]

Hi! The demo code you posted leaves successive screens with the following text:
←[0;0f
before each print.
Working on W10, with Python 3.9.
Visual Studio Code, "externalTerminal" on launch.json.

[aqasoft]

Happened with the previous example (the sinus wave) and with the current one (clock).

Hey there! The demo was recorded on Windows 10 using Python 3.9 so that's odd.. Seems like an issue with the terminal you're running the program in. Could you record your vs code terminal?

[aqasoft]

Hi Matthias! Yes indeed, I am sending you two recordings, the first, as you asked, from VScode internal terminal and the second one from an external terminal just calling the demo file without any obtrusions.

and 2:

[Matthias1590]

Thanks for reporting this! I was unaware that the module did not work in the windows command prompt and I'll try to find a way to make it work there too, I'll let you know when this is solved.

[Matthias1590]

I just released version 2.4.0, it should be fixed (if it is, please close this issue :)), thanks again for reporting this!

Hi Matthias, I cannot install the new release of ConsoleDraw nor build it from a local repo clone:

Installing directly from GIT since normal pip install consoledraw brings v3.x:

> pip install git+https://github.com/Matthias1590/ConsoleDraw.git
Defaulting to user installation because normal site-packages is not writeable

Really glad I can be of help in any way that you think.

[Matthias1590]

Should be fixed now, thanks for letting me know!

[aqasoft]

It installs properly now!
However:

1. It continues to work flawlessly in VScode's integrated terminal.
2. It looks much better, but it jumps up and down and skips seconds (back and forth) in CMD. Take a close look to the seconds in the image:

[Matthias1590]

Is that in cmd or in the python console? I believe there is a difference between the two and it worked for me in cmd, haven't tested it in the python console yet tho

[aqasoft]

It's not the Python Console. It is a standard CMD console, I've tried opening it in Admin mode, resizing fonts, many options.
I've even tried the sample code directly from ConEmu, and it produces the same effect as shown in the last gif.

I've just also tried with another PC, Python v3.10.0, W10 up-to-date, standard CMD console and the effect is the same.

I think maybe you should try in a clean VM? Maybe your testing environment is using some non-standard additional piece of software.

[Matthias1590]

Very odd, it behaves like that for me in the Python console but works in CMD. I tried testing on a vm and it gave me the expected result, could you show me what it looks like in the Python console?

[aqasoft]

I have two tests to report:

1. Python IDLE console. Fails when executing the demo code with the following output info:

>>> 
======================= RESTART: D:\_devpy\test\test1.py =======================
Traceback (most recent call last):
  File "D:\_devpy\test\test1.py", line 5, in <module>
    console = Console()

    self.update()

    grid = self.__generate_grid()
  File "C:\Program Files\Python39\lib\site-packages\consoledraw\console.py", line 31, in __generate_grid
    size = os.get_terminal_size()
ValueError: bad file descriptor
>>> 

screen capture:

2. Tested on a brand new fresh and clean install of W10Pro (old version: 1909) on VMware. The only SW added was GIT and Python 3.10.1.
ConsoleDraw was installed using the GIT repository, having the CMD console both in Admin mode and normal user mode (the target folder for the installations is different).

It produces the same result of the digital watch jumping up and down one line and the seconds skipping back and forth one second. Sorry to report this one, I really expected a different result.

original screen capture of the observed behavior:

Might take me a while to figure this one out, I'll keep you updated and do my best though.
