I tried this, but I can't see them in the Complex Modifications tab.

➜  KE-complex_modifications git:(master) ✗ make
bash scripts/update-json.sh
check docs/json/pc-rules.json
ok
docs/json/pc-rules.json
ruby scripts/lint-groups.rb
(cd docs && ruby ../scripts/make-distjs.rb > dist.json)

I did try restarting karabiner elements, but they still aren't there.

@dwatrous In the Complex Modifications tab you need to click the Add Rule button and the new rules will be visible there. The GUI only shows enabled rules with a button to remove them, the Add Rule popup lists the new rules with a button to Enable them. This caught me out too initially. The readme in the cloned repository is more up-to-date than this gist and does now mention this.

end is working, but not key "home"... i use MacOs Mojave, Karabiner last version

you don't need really this json, is already on 'pc-style' on included on:
https://github.com/pqrs-org/KE-complex_modifications/

the home/end keys on my logitech mx keyboard were driving me insane on my mac (11.5.2 big sur). for example, when editing a web-based textarea like this one, the home and end keys would act like page up and page down, making the whole webpage suddenly jolt up or down instead of just moving the inline cursor to the start or end of the line.

needless to say i really appreciate this snippet and the discussion! i followed the original instructions, accounted for the .json.erb file extension, and was able to reconfigure the keys in just a few minutes. thank you!

Note that (as of this writing) the docs folder has changed to be named public. So, you have to put pc-rules.json.erb in src/json and then the output will be in public/json/pc-rules.json.

Updated with the old version there too for historical purposes. I don't use a mac anymore at work so I can't test anything ;)

can anybody that already ran this post the resulting json please?

As of writing, this doesn't seem to work. Looks like the original repo lost its ability to compile ruby template files...
The workaround I ended up with is to simply use the "PC-Style Shortcuts" that can be imported into Karabiner from its own UI. They have all the shortcuts included in this gist.
