Build instruction on Windows.

[DYefremov]

It is necessary to create a separate instruction for launching and building a standalone package in MS Windows.

Can you explain more verbose?
Started from here with .spec file and pyinstaller.....

Launch

The best way to run this program from source is using of MSYS2 platform.

1. Download and install the platform as described here up to point 4.
2. Launch mingw64 shell.
   
3. Run first pacman -Suy After that, you may need to restart the terminal and re-run the update command.
4. Install minimal required packages: pacman -S mingw-w64-x86_64-gtk3 mingw-w64-x86_64-python3 mingw-w64-x86_64-python3-gobject mingw-w64-x86_64-python3-pip mingw-w64-x86_64-python3-requests
   Optional: pacman -S mingw-w64-x86_64-python3-pillow
   To support streams playback, install the following packages (the list may not be complete):
   For MPV pacman -S mingw-w64-x86_64-mpv ,
   For GStreamer pacman -S mingw-w64-x86_64-gst-libav mingw-w64-x86_64-gst-plugins-bad mingw-w64-x86_64-gst-plugins-base mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gstreamer
5. Download and unzip the archive with sources from preferred branch (e.g. master) in to folder where MSYS2 is installed. E.g: c:\msys64\home\username\
6. Run mingw64 shell. Go to the folder where the program was unpacked. E.g: cd DemonEditor/
   And run: ./start.py

To be continued...

Building a package

To build a standalone package, we can use PyInstaller.

1. Launch mingw64 shell.
2. Install PyInstaller via pip: pip3 install pyinstaller
3. Go to the folder where the program was unpacked. E.g: c:\msys64\home\username\DemonEditor\
4. Сopy and replace the files from the /build/win/ folder to the root .
5. Go to the folder with the program in the running terminal: cd DemonEditor/
6. Give the following command: pyinstaller.exe DemonEditor.spec
7. Wait until the operation end. In the dist folder you will find a ready-made build.

Appearance

To change the look we can use third party Gtk3 themes and Icon sets .
To set the default theme:

1. Сreate a folder "\etc\gtk-3.0\" in the root of the finished build folder.
2. Create a settings.ini file in this folder with the following content:

[Settings]
gtk-icon-theme-name = Adwaita
gtk-theme-name = Windows-10

In this case, we are using the default icon theme "Adwaita" and the third party theme "Windows-10".
Themes and icon sets should be located in the share\themes and share\icons folders respectively.
To fine-tune the default theme you use, you can use the win_style.css file in the ui folder.
You can find more info about changing the appearance of Gtk applications on the Web yourself.

Corrections and additions are welcome!

get error ..
My@LAPTOP-OM27EOQ1 MINGW64 ~/Demon $ ./start.py Traceback (most recent call last): File "C:\msys64-\home\My\Demon\start.py", line 26, in <module> from app.ui.main import start_app File "C:/msys64-\home\My\Demon/app/ui/main.py", line 38, in <module> from gi.repository import GLib, Gio, GObject ModuleNotFoundError: No module named 'gi'

I think not all dependencies were installed, or not installed correctly. In your case it looks like the package 'mingw-w64-x86_64-python3-gobject' is missing.

[luxorko]

after re-install get this:
My@LAPTOP-OM27EOQ1 MINGW64 /home/demon $ ./start.py Traceback (most recent call last): File "C:\msys64\home\demon\start.py", line 28, in <module> update_icon() File "C:\msys64\home\demon\start.py", line 10, in update_icon lines = f.readlines() File "C:/msys64/mingw64/lib/python3.9/encodings/cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 129: character maps to <undefined>

I already answered here. Unfortunately, I can't add anything new. Personally, I can't reproduce it. Perhaps for testing purposes, it makes sense to try changing the locale of the system itself. For example in English. What locale and OS are you using? Try running mingw64 shell and give command: locale

[luxorko]

OS Win 10- EN

My@LAPTOP-OM27EOQ1 MINGW64 ~ $ locale LANG= LC_CTYPE="en_US.UTF-8" LC_NUMERIC="C.UTF-8" LC_TIME="C.UTF-8" LC_COLLATE="C.UTF-8" LC_MONETARY="C.UTF-8" LC_MESSAGES="C.UTF-8" LC_ALL=

[DYefremov]

Yes, I can confirm. Really interesting. Occurs on Win 10 if the system locale is en_US.

In addition, you can try replacing the start.py file in the source folder with this one.

This should help! In addition, I slightly changed the main start script. It should also work, but I still recommend the method above!
