hotkey repeat

[wheresw...@gmail.com]

Is there a way to do automatic hotkey repeat when a hotkey is held?

Thanks,

Max

Hi

At the moment, no, we trigger callbacks when the keys are initially pressed down.

Out of interest, what's your use case for repeating hotkeys?

Cheers,

I'd like to be able to, say, move a window in a direction continuously by holding a hotkey. Could this be accomplished with modal hotkeys? Maybe using the pressedfn to activate a move and the releasedfn to stop it?

Thanks,

I thought this message was newer but anyway I implemented my own function for dealing with this

function keyRepeat(mods, key, delay, interval, repeatfn)

local modal_key = hs.hotkey.modal.new(nil, nil)

local key_repeat = false

local timer

timer = hs.timer.new(interval, function() if not key_repeat then timer:stop() else repeatfn() end end)

modal_key:bind(mods, key, 

function()

key_repeat = true

repeatfn()

hs.timer.doAfter(delay, function() if key_repeat then timer:start() end end)

end, 

function()

key_repeat = false

timer:stop()

end

)

modal_key:enter()

end

the delay parameter is there to not start repeating until x seconds, this was needed in my specific case where I wanted to use ctrl + j/j//h/l as movement keys, without it I would end up moving more than one line sometimes when pressing once, probably not needed in the cases where you want to resize or move window, etc, and using the same number as interval would be ideal

this is how I'm using it:

keyRepeat(ctrl_mod, 'j', 0.5, 0.1, function() hs.eventtap.event.newKeyEvent(no_mod, 'down', true):post() end)

keyRepeat(ctrl_mod, 'k', 0.5, 0.1, function() hs.eventtap.event.newKeyEvent(no_mod, 'up', true):post() end)

keyRepeat(ctrl_mod, 'h', 0.5, 0.1, function() hs.eventtap.event.newKeyEvent(no_mod, 'left', true):post() end)

keyRepeat(ctrl_mod, 'l', 0.5, 0.1, function() hs.eventtap.event.newKeyEvent(no_mod, 'right', true):post() end)

So, interestingly enough, the system APIs for doing hotkeys don't actually support repeating and so the typical way people do it is exactly how your Lua implementation works :)

I am considering adding support for a repeat callback to hs.hotkey, but I'm now wondering if putting your Lua version in the Getting Started Guide would be sufficient.

What do people think?

Thanks, boolemilio, that looks great!

Chris: That's odd, given that the keyboard preferences have options for key repeat. But I'd vote to have it be added to hs.hotkey, since otherwise, people will just be copy-pasting it wholesale into their inits, and that seems to go against the modularity of Mjolnir and the abstraction of Hammerspoon.

As of http://git.io/xP99 I've pushed what I think is complete support for a third callback function to hs.hotkey.new() and hs.hotkey.bind(), so you can now have a callback for pressing a key, one for releasing a key and one for the key being held down long enough to repeat.

It'll likely be a few days before 0.9.25, so I'll keep testing it locally and see if I can find any issues (although mostly I'll be testing normal hotkeys, to make sure this hasn't broken anything!)

Thanks Chris, that looks great! Does it support customization for repeat delay and repeat rate?

[Max Rothman]

Also, it looks like you can access at least the user settings for key repeat delay and rate: http://stackoverflow.com/questions/13073328/cocoa-detecting-key-held-down

Hi

Haha, I knew I'd get asked for that, but I didn't expect it straight away ;)

Right now, no, but the NSEvent values you found should make it very easy to add. Thanks!

Hi

Oh, also, I meant to say that unlike the code in your link, I have made the timer cancellation be *extremely* conservative. If it sees *any* event, it cancels the repeat, it doesn't check for the Release event of the specific key that's repeating. I want to be very very sure that we don't get people stuck in a repeat loop.

Also I cancel the timer if the repeat function causes a Lua trace back.
