令人敬畏的顽皮通知

Question

我正在基于 playerctl 为 Awesome 创建一个小部件。 当我使用 awesomeclient 进行测试时，它工作正常。

awesome-client '

local stdout = "Playing;Eurythmics;Miracle of Love;file:///home/mgaber/Workbench/awesome/stags1.7/testing/173308_26.png"

local words = {}
for w in stdout:gmatch("([^;]*)") do
    print(w)
    table.insert(words, w)
end

mpdstatus = words[1]
current_song = words[2]
artist = words[3]
song_art = words[4]

a,b,c = 1, 2, 3

local song_art = string.sub( song_art,8, -1)

local awful = require("awful");
local gears = require("gears")
local naughty= require("naughty"); 
local bubble =function(cr, w, h)
        return gears.shape.infobubble(cr, w, h, 20, 10, w/2 - 30)
    end
naughty.notification(
{
margin = 15,
position = "top_left",
width = 640,
height = 160,
title = mpdstatus,
text=current_song .. " By " .. artist .. a .. c,
image = song_art});

'

但是，当我将代码放入 rc.lua 时，图标没有出现，我进行了测试，我的代码按预期工作，图像文件被传递给 naughty.notification..

    local function show_MPD_status()
        spawn.easy_async(GET_MPD_CMD, function(stdout, _, _, _)
            -- notification = naughty.notification {
            naughty.notification {
                margin = 10,
                timeout = 5,
                hover_timeout = 0.5,
                width = auto,
                height = auto,
                title = mpdstatus,
                text = current_song .. " by " .. artist,
                image = artUr
            }
        end)
    end

很棒的版本

$ awesome --version             
awesome v4.3-895-g538586c17-dirty (Too long)

我收到一条显示通知 “状态” 艺术家的歌曲，没有图像或图标。

谢谢

我认为这是 Lua 版本的问题。我不知道具体细节，但它在 Lua 5.3 和 5.4 上运行良好——而在 LuaJIT、Lua 5.1 和 5.2 中，你会看到你提到的同样缺乏艺术家和歌曲艺术。您是否碰巧知道您的 AwesomeWM 是针对哪个版本的 Lua 编译的？

#! /usr/bin/env lua
print( _VERSION )

local stdout  = 'Playing;Eurythmics;Miracle of Love;file:///home/mgaber/Workbench/awesome/stags1.7/testing/173308_26.png'

local words  = {}
for w in stdout :gmatch( '([^;]*)' ) do
    if #w > 0 then
        print( w )
        words [#words +1] = w
    end
end

local mpdstatus  = words[1]     ; print( mpdstatus )
local current_song  = words[2]    ; print( current_song )
local artist  = words[3]            ; print( artist )
local song_art  = words[4] :sub( 8 )  ; print( song_art )

local awful  = require('awful')
local gears  = require('gears')
local naughty  = require('naughty')

local bubble  = function( cr, w, h )
    return gears .shape .infobubble( cr, w, h, 20, 10, w /2 -30 )
end

naughty .notification(  {
    margin  = 15,
    position  = 'top_left',
    width  = 640,
    height  = 160,
    title  = mpdstatus,
    text  = current_song ..' By ' ..artist,
    image  = song_art  }  )

我终于设法解决了这个问题。 问题是由塑造通知的 Widget 模板引起的，并且配置错误，删除模板修复了它
