除了函数输出中返回的upspeedgraph
s 和s 之外,一切正常。downspeedgraph
conky_show_netdevs()
这是我可以看到的图表图像(图像最后一部分中的小线;在出现文本“UP”和“DOWN”的行上):
据我所知,我认为这个问题是由于每次 conky 重新加载时都会解析 lua 函数的内容而引起的,这可能会导致图形重新加载。所以,我尝试将conky的更新间隔增加到10秒。但仍然没有运气:(
答案1
不幸的是,lua_parse
它将在每个更新周期运行,因此每次都会创建一个新的空图。如果您只想在开始时创建一次配置的网络部分,您可以利用该.conkyrc
文件只是一个 lua 文件这一事实,因此您可以将 lua 代码放入其中。
使用它来调用生成配置字符串的修订函数,并将其连接到变量上conky.text
。 (你曾经能够在 lua 中以全局方式访问它,但这似乎不再可能了)。
所以终止.conkyrc
与
conky.text = [[
...
${color1}NET: ${hr 2}${color2}
]]
require 'netdevs'
conky.text = conky.text .. conky_show_netdevs()
并编辑 lua 以删除任何 conky 调用,然后返回配置:
-- conky_show_netdevs : template for network
function conky_show_netdevs()
local netdevs_handle = io.popen(...)
local result = ""
for netdev in netdevs_handle:lines() do
result = result ...
netdevs_handle:close()
return result
end
