二改模版笔记

自动重新加载HS

function reloadConfig(files)doReload = falsefor _,file in pairs(files) doif file:sub(-4) == ".lua" thendoReload = trueendendif doReload thenhs.reload()end
end
myWatcher = hs.pathwatcher.new(os.getenv("HOME") .. "/.hammerspoon/", reloadConfig):start()
hs.alert.show("Config loaded")

调节音量

function changeVolume(diff)return function()local current = hs.audiodevice.defaultOutputDevice():volume()local new = math.min(100, math.max(0, math.floor(current + diff)))if new > 0 thenhs.audiodevice.defaultOutputDevice():setMuted(false)endhs.alert.closeAll(0.0)hs.alert.show("Volume " .. new .. "%", {}, 0.5)hs.audiodevice.defaultOutputDevice():setVolume(new)end
endhs.hotkey.bind({"shift","ctrl",'command'}, 'Down', changeVolume(-3))
hs.hotkey.bind({"shift","ctrl",'command'}, 'Up', changeVolume(3))
