问题[conky](unix)

这是我的conkyrc：

conky.config = {
    use_xft = true, -- use xft?
    font = 'DejaVuSans:size=9', -- font name
    xftalpha = 1,
    uppercase = false, -- all text in uppercase?
    pad_percents = 0,
    text_buffer_size = 2048,
    override_utf8_locale = true, -- Force UTF8? note that UTF8 support required XFT
    use_spacer = 'none', -- Add spaces to keep things from moving about?  This only affects certain objects.

    update_interval = 1, -- Update interval in seconds
    double_buffer = true, -- Use double buffering (reduces flicker, may not work for everyone)
    total_run_times = 0, -- This is the number of times Conky will update before quitting. Set to zero to run forever.

    -- Create own window instead of using desktop (required in nautilus)
    own_window = true,
    own_window_class = 'Conky',
    own_window_transparent = true,
    own_window_argb_visual = true,
    own_window_argb_value = 255,
    own_window_type = 'desktop', -- transparency seems to work without this line
    own_window_hints = 'undecorated,sticky,below,skip_taskbar,skip_pager',

    -- Minimum size of text area
    minimum_height = 50,
    minimum_width = 210,

    draw_shades = false, -- draw shades?
    draw_outline = false, -- draw outlines?
    draw_borders = false, -- draw borders around text?
    draw_graph_borders = false, -- draw borders around graphs
    stippled_borders = 0, -- stripled borders?

    imlib_cache_size = 0, -- Imlib2 image cache size, in bytes. Increase this value if you use $image lots. Set to 0 to disable the image cache.

    -- Gap between borders of screen and text. Same thing as passing -x at command line
    gap_x = 90,
    gap_y = 5,

    alignment = 'middle_right', -- alignment on {y_axis}_{x_axis}

    cpu_avg_samples = 2, -- number of cpu samples to average. set to 1 to disable averaging
    net_avg_samples = 2, -- number of net samples to average. set to 1 to disable averaging

    no_buffers = true, -- Subtract file system buffers from used memory?

    default_color = 'e0e0e0',
    default_shade_color = '000000',
    default_outline_color = '000000',

    temperature_unit = 'celsius',

    color1 = 'ff55ff', -- heading's color
    color2 = 'ffffff', -- normal text's color

    lua_load = '.conky/netdevs.lua',
};

conky.text = [[
...
${color1}NET: ${hr 2}${color2}${lua_parse conky_show_netdevs}
...
]]

这是.config/netdevs.lua：

-- conky_show_netdevs : template for network
-- usage : ${lua_parse conky_show_netdevs}

prev_result = ""

function conky_show_netdevs()
    updates = tonumber(conky_parse("${updates}"))
    interval = 10
    timer = (updates % interval)

    if timer == 0 or prev_result == "" then
        local netdevs_handle = io.popen("ip -j link show up | jq -r '.[] | select(.operstate == \"UP\" and .ifname != \"lo\") | .ifname'")
        local result = ""

        for netdev in netdevs_handle:lines() do
            result = result .. "\nIP (${color1}" .. netdev .. "${color2}): ${alignr}${addr " .. netdev .. "}\n" ..
                     "${color2}Up: ${color2}${upspeed " .. netdev .. "}/s${color1}${alignr}${upspeedgraph " .. netdev .. " 10,170}\n" ..
                     "${color2}Down: ${color2}${downspeed " .. netdev .. "}/s${color1}${alignr}${downspeedgraph " .. netdev .. " 10,170}\n" ..
                     "${color2}Total Down: ${color2}${totaldown " .. netdev .. "}${alignr}Total Up: ${totalup " .. netdev .. "}\n"
        end

        netdevs_handle:close()

        if result ~= "" then
            prev_result = result
        else
            prev_result = "\n"
        end
    end

    return prev_result
end

除了函数输出中返回的upspeedgraphs 和downspeedgraphs 之外，一切正常。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重新加载 conky 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:( 👎。

请告诉我为什么会发生这种情况以及如何解决这个问题？

谢谢😊！

我无法打印我的 GPU 使用情况我有以下正则表达式：

${execgraph 16,235 $(nvidia-smi --query-gpu=utilization.gpu --format=csv -l 5 | sed -n '2p' | grep -Po "\\d+")}

哪个打印想要的值，但由于某种原因，图形不会呈现。

我错过了什么？

我正在尝试加载一个.png以在 conky 中显示电池图标。到目前为止，我已经尝试使用 eval 嵌套函数调用，但我似乎找不到解决方案。

这是我的非工作 conky.text：

conky.text = [[
  ${image ${lua battery_icon $battery_status $battery_icon}}
]]

我的battery_icon函数如下所示：

function conky_battery_icon(battery_status, battery_percent)
  if (battery_status == "charging")
  then
    icon = "charging-battery.png";
  else 
    ...
  end

  return("/path/to/icons/" .. icon);
end

我检查了该功能是否有效，并且可以通过将以下行添加到我的conky.text：

${lua battery_icon $battery_status $battery_percent}

如何使用返回的路径battery_icon将文件加载到 conky's 中image？

我想列出 conky 上的最后 3 次登录，所以它看起来像这样

格式可以很。

我最近用 conky 重做了我的 i3bar。今天早上当我醒来时，我的酒吧里有无法识别的字符符号（我的 conkyrc 文件中有空格）。据我所知，什么都没有真正改变，我不确定为什么会在一夜之间发生这种情况。我的conkyrc：

background no
out_to_x no
out_to_console yes
update_interval 1
total_run_times 0
use_spacer right

TEXT
${if_mpd_playing}${mpd_artist}   ${mpd_title}${endif}          \
  ${wireless_essid wlp7s0}          \
  ${exec amixer get Master | sed -n 's/^.*\[\([0-9]\+\)%.*$/\1/p'| uniq}          \
  ${cpu cpu}%          \
  $memperc%          \
  ${time %a %b %d}          \
  ${time %I:%M %P}          \
  ${battery_percent BAT0}% ${exec acpi -b | awk "{print $1}" | sed 's/\([^:]*\): \([^,]*\), \([0-9]*\)%.*/\2/'}          

我的 i3bar 配置：

bar {
        status_command conky -c $HOME/.i3/conky/conkyrc
        mode dock
        position top
colors {
        background #F1F2F6
        statusline #788491
        separator #51c4d4

        focused_workspace  #F1F2F6 #F1F2F6 #4FC0E8
        active_workspace   #F1F2F6 #F1F2F6 #4FC0E8
        inactive_workspace #F1F2F6 #F1F2F6 #C1D1E0
        urgent_workspace   #F1F2F6 #F1F2F6 #C1D1E0
    }
}

我在 Ubuntu 16.10 (x86-64)、内核 4.8.0-59-generic、Cinnamon 3.0.7 中使用 conky 1.10.3 (conky-all)。

如何为 diskio 创建一个栏（实际上，一个用于 diskio_read，另一个用于 diskio_write）？
Conky 有 diskio（它给出了一个数字）和 diskiograph - 没有条。

我尝试过，但找不到使用类似${execbar $diskio}.

我还弄乱了一个 lua 脚本，即 wlourf 的 BARGRAPH WIDGET v2.1，http ://u-scripts.blogspot.com/2010/07/bargraph-widget.html但是，虽然使用

{
    name="cpu",
    --arg="%S",
    max=100,
    angle=90,
    alarm=50,
    bg_colour={0x00ff00,0.25},
    fg_colour={0x00ff00,1},
    alarm_colour={0xff0000,1},
    x=0,y=610,
    blocks=1,
    height=250,width=25,
    smooth=true,
    mid_colour={{0.5,0xffff00,1}}

}

工作，如果我把“diskio”而不是“cpu”我得到一个空栏（而conky的diskiograph清楚地显示了磁盘IO）。
