final AUR package:

https://aur.archlinux.org/packages/doc2x

official website provides win exe file, size is around 70-80M, likely to be electron.

download it, check the string.

strings doc2x.exe | grep '^Chrome/[0-9.]* Electron/[0-9]'
Chrome/112.0.5615.204 Electron/24.8.8

after some 7z x + asar e, get the app folder

download the electron24 dependency.

ELECTRON_ENABLE_LOGGING=1 electron24 app/

At first, it white screen.

check the log, seems will check the system.

do some brute force replacement.

	sed -i '[email protected]@(true)@g
		[email protected]@"darwin"@g' app/dist/main/index.cjs # mac has window decoration

then it works.

it requires weixin to work, so I asked others.
