Awesome naughty notifications - lua

Question

I'm creating a widget for Awesome based on playerctl.
When i test with awesomeclient it works fine.
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});
'
However when i put the code in rc.lua the icon doesn't appear, I tested and my code works as supposed to and the image file is passed to 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
Awesome Version
$ awesome --version
awesome v4.3-895-g538586c17-dirty (Too long)
• Compiled against Lua 5.3.6 (running with Lua 5.3)

I get a notification displaying
"Status"
Song by Artist with no image or icon.
Thanks

Answer 1

I think it's a Lua version issue. I don't know the specifics, but it runs fine on Lua 5.3 and 5.4 - wheras within LuaJIT, Lua 5.1 and 5.2 you see the same lack of artist and song art that you mention. Do you happen to know what version of Lua your AwesomeWM is compiled against?
#! /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 } )
Edit:
It's putting more entries in your words list than expected. Filter out blank entries.

Answer 2

I finally managed to sort this out.
The problem was caused by a Widget template that shapes the notification and was misconfigured, removing the template fixed it
