Lua 在我的Hammerspoon脚本中，重复键被延迟

我将我的CAPSLOCK绑定到F18（卡拉宾）以用作修改键。我试图模拟CAPSLOCK+h，j，k，l来充当VIM移动键。一切正常，但重复时存在延迟问题。也就是说，当我按下CAPSLOCK+h时，速度非常慢，这应该模拟按下“我也有类似的迟钝。看起来在最新版本中引入了一些缓慢性。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，因此您可以看到它的使用情况。还要注意，我正在将5个参数传递到for key repeating中指定的

hs.hotkey.bind

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
)

关于慢度

是的，这是目前的正确答案-hs.eventtap.keyStroke（）实际上是同一个newKeyEvent（）对，中间有一个hs.timer.usleep（）。我们增加了短暂的睡眠，试图避免关键事件的无序发生。下一个版本将添加一个可配置的延迟，因此您可以在需要时将其关闭：）

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
)
