Convert as much as possible from Hammerspoon to Karabiner-Elements

[cdzombak]

Now that Karabiner-Elements is a bit more mature, I want to try to move as much as I can from Hammerspoon into Karabiner.

Wondering if you found a working implementation for:

Using goku, I tried implementing ESC to toggle a "capslock" mode by setting variable "capslock" 1 and then, when in capslock mode, having each a-z keypress trigger !Sa-z. Unfortunately I can't figure out how to make the toggle happen (e.g. by pressing ESC again)--I can only get it to be on or off, but not switch between the two. Have you had any luck?

@cdzombak If you still interested in SD mode, here's my Goku config which generates karabiner config file within Jason's repo.

Please note that I've been using this mode for so many years and I tweaked it a bit with more keys.

Background info from jasonrudolph/keyboard#71 (comment) :

It's possible to entirely remove the dependency on Karabiner-Elements, but in my experience, doing so has always involved some UX compromises.

Back in 2018, pqrs-org/Karabiner-Elements#545 led me to remove the dependency on Karabiner-Elements and implement everything with Hammerspoon, and I shipped that change in jasonrudolph/keyboard v4.0.0.

That worked, but I found the UX of that particular implementation to be inferior as described in #38. (Perhaps there's an alternative Hammerspoon-based implementation that would provide UX comparable to the Karabiner-Elements implementation, but I'm not aware of such an implementation.) So once pqrs-org/Karabiner-Elements#545 was resolved, #38 reinstated the use of Karabiner-Elements.

The problems described in #40, #59, and #60 were also side effects of removing the dependency on Karabiner-Elements. #61 resolved those issues by porting (S)uper (D)uper Mode from Hammerspoon to Karabiner-Elements.

With that in mind, I will likely postpone my personal upgrade to Big Sur until https://github.com/pqrs-org/Karabiner-DriverKit-VirtualHIDDevice is capable of supporting all the existing functionality in this repository.

I hope that helps.
