关键重复在我的Hammerspoon脚本中被延迟

Question

我有我的CAPSLOCK绑定到F18（karabiner）充当修饰键。我试图模拟CAPSLOCK + h，j，k，l作为VIM运动键。一切正常，但重复时有延迟问题。也就是说，当我按下CAPSLOCK + h时，它会非常缓慢，它应该模拟重复按下“< - ”键，但它非常延迟，并且每秒只发送一次。关于为什么发生这种情况的任何想法我的init.lua低于：

-- A global variable for the Hyper Mode 
k = hs.hotkey.modal.new({}, "F17") 

-- Enter Hyper Mode when F18 (Hyper/Capslock) is pressed 
pressedF18 = function() 
    k.triggered = false 
    k.modifier = false 
    k:enter() 

    trigger_modifier = function() 
    k.modifier = true 
    end 

    -- Only trigger as modifier if held longer than thisj 
    hs.timer.doAfter(0.35, trigger_modifier) 
end 

-- Arrow keys 
k:bind({}, 'h', function() 
    hs.eventtap.keyStroke({}, 'Left') 
    k.triggered = true 
end) 

k:bind({}, 'j', function() 
    hs.eventtap.keyStroke({}, 'Down') 
    k.triggered = true 
end) 

k:bind({}, 'k', function() 
    hs.eventtap.keyStroke({}, 'Up') 
    k.triggered = true 
end) 

k:bind({}, 'l', function() 
    hs.eventtap.keyStroke({}, 'Right') 
    k.triggered = true 
end) 

-- Leave Hyper Mode when F18 (Hyper/Capslock) is pressed, 
-- send ESCAPE if no other keys are pressed. 
releasedF18 = function() 
    k:exit() 

    if not k.triggered then 
    -- If hotkey held longer than this amount of time 
    -- let it remain as modifier and don't send ESCAPE 
    if not k.modifier then 
     hs.eventtap.keyStroke({}, 'ESCAPE') 
    else 
     print("Modifier detected") 
    end 
    end 
end 

-- Bind the Hyper key 
f18 = hs.hotkey.bind({}, 'F18', pressedF18, releasedF18)

我有一些类似的缓慢。看起来在最新版本中引入了一些缓慢。您可以使用下面的fastKeyStroke函数调用较低级别的函数。我已经包含了我的hjkl实现，所以你可以看到它的使用。另请注意，我将docs中指定的5个参数传递给hs.hotkey.bind以进行密钥重复。

local hyper = {"shift", "cmd", "alt", "ctrl"} 

local fastKeyStroke = function(modifiers, character) 
    local event = require("hs.eventtap").event 
    event.newKeyEvent(modifiers, string.lower(character), true):post() 
    event.newKeyEvent(modifiers, string.lower(character), false):post() 
end 

hs.fnutils.each({ 
    -- Movement 
    { key='h', mod={}, direction='left'}, 
    { key='j', mod={}, direction='down'}, 
    { key='k', mod={}, direction='up'}, 
    { key='l', mod={}, direction='right'}, 
    { key='n', mod={'cmd'}, direction='left'}, -- beginning of line 
    { key='p', mod={'cmd'}, direction='right'}, -- end of line 
    { key='m', mod={'alt'}, direction='left'}, -- back word 
    { key='.', mod={'alt'}, direction='right'}, -- forward word 
}, function(hotkey) 
    hs.hotkey.bind(hyper, hotkey.key, 
     function() fastKeyStroke(hotkey.mod, hotkey.direction) end, 
     nil, 
     function() fastKeyStroke(hotkey.mod, hotkey.direction) end 
    ) 
    end 
)
