令人敬畏的cm temp小部件

我最近开始使用awesome wm 4.2版，非常喜欢它;大大改善了我的工作流程。我尝试了一些主题，如模仿和其他，但他们太喜欢我了。我喜欢默认配置，并在这里阅读：https://awesomewm.org/apidoc/index.html以及来自copycats和其他人的rc.lua和theme.lua文件，并实现了其中一些;键绑定，布局操作，启动程序。我想创建一个显示cpu temp的小部件，我按照这里的https://awesomewm.org/apidoc/classes/awful.widget.watch.html跟随这些内容：

wibox.widget.textbox('  |  '),
awful.widget.watch(
  'bash -c "cat/sys/class/hwmon/hwmon0/device/temp1_input"', 15),
wibox.widget.textbox('  |  '),
awful.widget.watch(
  'bash -c "cat /sys/class/hwmon/hwmon0/device/temp3_input"', 15),

它有效，但它显示大数字，即43000而不是43.我怎么能改变它？如果可能的话，温度为43°C。

答案

如果你得到正确的数字，只想将它除以1000，你可以使用optional callback：

awful.widget.watch('bash -c "cat /sys/class/hwmon/hwmon0/device/temp1_input"', 15, 
  function(widget, s) widget:set_text(tonumber(s)/1000) end)
