I’m making an attempt to create a lua script to work with hammerspoon which intends to swap cmd+left/proper arrow keys to behave like choice+left/proper arrow keys however it would not appear to work. Right here is the script
-- outline the important thing codes for command, choice, left arrow, and proper arrow
-- native cmdKey = 0x37
-- native optKey = 0x3A
-- native leftArrow = 0x7B
-- native rightArrow = 0x7C
native keyCodes = hs.keycodes.map
native cmdKey = keyCodes['cmd']
native optKey = keyCodes['alt']
native leftArrow = keyCodes['left']
native rightArrow = keyCodes['right']
-- outline a variable to maintain observe of whether or not the keys have been swapped
native keysSwapped = false
-- outline a operate to deal with key occasions
operate handleKeyEvent(occasion)
if occasion:getType() ~= hs.eventtap.occasion.varieties.keyDown then
return false
finish
native keyCode = occasion:getKeyCode()
native flags = occasion:getFlags()
print("keyCode: " .. keyCode)
for k, v in pairs(flags) do
print(" " .. k .. ": " .. tostring(v))
finish
-- verify if the left or proper arrow key's pressed together with command or choice
if (keyCode == leftArrow or keyCode == rightArrow) and flags.cmd then
-- swap the command and choice flags
flags.cmd, flags.alt = flags.alt, flags.cmd
-- replace the variable to point that the keys have been swapped
keysSwapped = true
finish
print("keysSwapped: " .. tostring(keysSwapped))
for k, v in pairs(flags) do
print(" " .. k .. ": " .. tostring(v))
finish
-- if some other key's pressed together with command or choice, revert the swap
if (keysSwapped and (not flags.cmd or (keyCode ~= leftArrow and keyCode ~= rightArrow))) then
-- swap the command and choice flags again
flags.cmd, flags.alt = flags.alt, flags.cmd
-- reset the variable to point that the keys are now not swapped
keysSwapped = false
finish
-- create a brand new occasion with the modified flags
-- native newEvent = hs.eventtap.occasion.newKeyEvent(flags, keyCode, occasion:isDown())
-- native newEvent = hs.eventtap.occasion.newKeyEvent(flags, keyCode, occasion:getType() == hs.eventtap.occasion.varieties.keyDown)
native newEvent = hs.eventtap.occasion.newKeyEvent(flags, keyCode, occasion:getType() == hs.eventtap.occasion.varieties.keyDown, false)
-- inject the brand new occasion into the system occasion stream
return true, {newEvent}
finish
-- create a brand new occasion faucet to seize key occasions
native eventTap = hs.eventtap.new({hs.eventtap.occasion.varieties.keyDown, hs.eventtap.occasion.varieties.keyUp}, handleKeyEvent)
-- begin the occasion faucet
eventTap:begin()
The script above is written by chatgpt(attributable to lack of awareness on lua and hammerspoon) and I’ve modified it with some digging from hammerspoon web site. I’ve printed logs to see whether or not swap is going on and it does appear to occur, however when cmd+arrow keys are clicked collectively the cursor would not skip a phrase.
I’m utilizing lua fairly than some other methodology as a result of ultimately I need to have this swap performance solely when I’m utilizing the shortcut in textual content fields and to my restricted data lua and hammerspoon are acceptable for that.
