need help with conky .lua script please [SOLVED]

[Logansfury]

Hello everyone,

I am trying to use conky to display a random image and play a corresponding .mp3 file with mpg123.

I have a directory with .png files numbered 1-51.png and a directory of .mp3 files named 1-51.mp3

Here is the conf:

Code: Select all

 
 --[[
Bleys 2024 

]]
conky.config = {
-- — Conky settings

	background = false,
	total_run_times = 0,
	no_buffers = true,	

-- — Window specifications with Background

	own_window = true,
	own_window_type = dock,
    own_window_hints = 'skip_taskbar,skip_pager,undecorated,above',
    own_window_transparent = false,
	own_window_argb_visual = true,
	own_window_argb_value = 0,
	own_window_colour = '000000', 
	
	double_buffer = true,
	minimum_width = 324, minimum_height = 214,
	alignment = 'middle_middle',
	
	gap_x = 20,
	gap_y = 20,

    update_interval = 3600,

-- Lua Load
	lua_load = '/home/logansfury/.conky/Biohazzard/test.lua',
	lua_draw_hook_post = 'main',		
};
conky.text = [[

]];

and here is the .lua

Code: Select all

require 'cairo'
require "imlib2"
home_path = os.getenv ('HOME')

function fDrawImage(cr,path,xx,yy,ww,hh,arc)
    cairo_save (cr)
    local img =  cairo_image_surface_create_from_png(path)
    local w_img, h_img = cairo_image_surface_get_width(img), cairo_image_surface_get_height(img)
    cairo_translate (cr, xx, yy)
    if arc then
        cairo_rotate (cr, arc)
    end
    cairo_scale (cr, ww/w_img, hh/h_img)
    cairo_set_source_surface (cr, img, -w_img/2, -h_img/2)
    cairo_paint (cr)
    cairo_surface_destroy (img)
    collectgarbage ()
    cairo_restore (cr)
end

function conky_main()
    if conky_window == nil then
        return
    end
    local cs = cairo_xlib_surface_create(conky_window.display, conky_window.drawable, conky_window.visual, conky_window.width, conky_window.height)
    local cr = cairo_create(cs)
        math.randomseed(os.time())
        local random_number = math.random(1, 51)
        fDrawImage(cr, '/home/logansfury/Pictures/microsoft_jokes/' .. tostring(random_number) .. '.png', 162, 107, 324, 214)
       --end
    cairo_surface_destroy(cs)
    cairo_destroy(cr)
end

Currently what I have works. It randomizes a different number every time, and is showing the .png file.
Now I need an edit for mpg123 to navigate to /home/logansfury/Music/eyegor/ and play the $random_number .mp3

Can anyone provide code to help?

Thanks for reading,

Logan

look at the last 6 lines of the .lua file:

Code: Select all

        local random_number = math.random(1, 51)
        fDrawImage(cr, '/home/logansfury/Pictures/microsoft_jokes/' .. tostring(random_number) .. '.png', 162, 107, 324, 214)
       --end
    cairo_surface_destroy(cs)
    cairo_destroy(cr)
end

but it should look like these 5 lines instead:

Code: Select all

        local random_number = math.random(1, 51)
        fDrawImage(cr, '/home/logansfury/Pictures/microsoft_jokes/' .. tostring(random_number) .. '.png', 162, 107, 324, 214)
    cairo_surface_destroy(cs)
    cairo_destroy(cr)
end

now make it look like that:

Code: Select all

        local random_number = math.random(1, 51)
        fDrawImage(cr, '/home/logansfury/Pictures/microsoft_jokes/' .. tostring(random_number) .. '.png', 162, 107, 324, 214)
        local dangler = io.popen('some bash command goes here')
        dangler:close()
    cairo_surface_destroy(cs)
    cairo_destroy(cr)
end

Partial success

It looks like a good starting point. What happened was:

- it played an mp3 (7.mp3)
- it then played a 2nd mp3 (22.mp3)
- after 2nd mp3 completed, it showed the image corresponding to 2nd mp3 played.

What I am looking for is

- display the .png image first
- immediately play corresponding mp3
- code to wait while mpg123 plays
- code to wait 2 seconds after mpg123 stops playing
- code to stop showing the .png

Here is the terminal output from the launch:
