One might add that the easiest way of running acme on Windows, Mac OS X and Linux with the same setup is to use the Inferno OS version which runs in a VM and there is a prepackaged form of it: acme-sac. I have used this for years to have a consistent editor on all thes OSs with minimal fuss to set it up.
I found the Inferno environment to work subtly differently than plan9port’s in a way that I don’t remember but was infuriating at the time.
Yes it is slightly different, mostly the mountpoints are. It is still usable though and the system is documented rather well… The Programming in Inferno book also helps…
This may have changed since last I tried this method of running plan9port acme on Windows under Xming, but I did have the problem that right-click search within a pane does not snap the cursor position to the next result as per other platforms. This is probably an Xming thing. As @C-Keen mentions, acme-sac is working well for me on Win10 (with -g2560x1440)
