Cannot Detect If On Devel Branch about logoslinuxinstaller HOT 4 CLOSED

some breadcrumbs to follow:

• winehq packages for ubuntu install wine to /opt/wine-{$branch}/
• The current appimage for 8.19 does the same, which you can see if you:
  • mount the image with wine-${blahblahblah}.appimage --appimage-mount
  • note the mount path in the terminal output
  • open another terminal to this path and do ls ${mount_path}/opt/, and you will see either wine-staging, wine-devel, or wine-stable in that folder

AppImages also have a command to extract certain files. Maybe this could be used to sniff out the wine branch used without having to mount the AppImage. For example, I've found that it can be discovered inside mscoree.dll:

$ grep -aEo 'wine-[a-z]+' /opt/wine-stable/lib/wine/i386-windows/mscoree.dll 
wine-stable
# or, without knowing the full path ahead of time (less useful if you have multiple wine versions installed inside the search folder:
$ find /opt -name mscoree.dll -exec grep -aEo 'wine-[a-z]+' {} \; 
wine-stable
wine-stable
# for an AppImage this seems to work (if you don't trust the filename):
$ grep -aEo 'wine-[a-z]+' wine-devel_8.19-x86_64.AppImage
wine-devel

Searching a DLL might work, as that should be available on all systems if we search the right directory. We would need to pair the wine binary candidate with the dir containing its DLLs and then we should be able to search whatever we want. It might even be faster than waiting on a wine --version check since we don't need to wait for the heavy wine bin to load.

We might then be able to simplify the whole thing even, as then we could determine the binary's branch with a simple sed or awk.

I've started working on this in issue32 branch. It detects but doesn't yet handle AppImages, though.
