This feature exists in GNUstep. Is this not sufficiently free?
The file nextstep/INSTALL says: Mac OS X 10.6 or later GNUstep "Startup
0.23" or later which are adequate minimums to support this function.
If you think we really need complete parity with Linux desktop systems
beyond GNUstep, based on some research this morning, we may be able to leverage
dbus messages for desktops that support for "count" (numeric only, sheesh)
/ "count-visible". This functionality appears not to be tied to the
running process as on macOS/GNUstep but to a "URL" like
"application://{appname}.desktop"
where I guess appname would be emacs or Emacs, I dunno yet how this really
works when there are more than one running copies of an app process. I'll
experiment and see if I can tease this out.
If this seems easy and you're 100% adamant that GNUstep is insufficiently
free, I can try to craft a more generic API that supports numeric counts
for Linux desktop shells, and text labels for macOS/GNUstep.
Anyone reading this thread that has experience on Linux desktops that
support count/count-visible and you have a few minutes, contact me.
