i've used ffmpeg to extract the image from audio file, my config

MPD_PORT : "6600"
MUSIC_DIRECTORY : "~/Media/music/"
SEEK_OFFSET : 5
CACHE_DIR : "~/.config/gomp/.cache/"
DEFAULT_IMAGE_PATH : "~/.config/gomp/default_art.png"

and the audio i was playing was located in ~/Media/music/nightcore/

Just found this project, looks interesting. Installed it from aur, but ran into this error.

panic: runtime error: invalid memory address or nil pointer dereference

Cloned the git repo, built it from there, same error. Then I checked out to an earlier commit. Same error. Seems it might be something on my side. Here is my config.yml

MPD_PORT : "6600"
MUSIC_DIRECTORY : "~/Music"

Please advise. Also, sorry for making an empty issue and then editing it later. Was about to type this up when I misclicked and then something came up.

Steps to build the latest version : 1/ go build on master branch 2/ get default version https://github.com/aditya-K2/goMP/blob/master/sample_config.yml to .config/$USER/goMP/config.yml and change MUSIC_DIRECTORY

The program needs a local mpd configuration file : No config File for mpd Found panic: open $USER/.config/mpd/mpd.conf: no such file or directory but i'm using config file at /etc/mpd.conf (why not add an option to set config file path ?)

Building the project works fine, but when running the executable, I get this message :

how to corret it :

  Could Not Generate the File Map
  Make Sure You Mention the Correct MPD Port in the config file.
  panic: EOF

  goroutine 1 [running]:
  main.main()
      .../gomp/main.go:65 +0x2112
  exit status 2

(I used a random image as the default, please pay no attention) The first terminal (up) is st, the second one (down) is alacritty. I also tested with urxvt and got the same issue.

Sidenote : What are the naming conventions, so the album picture is read ?

I haven't had any success getting gomp to run to this point. I decided to try troubleshooting a little bit and have a slightly better understanding of why now. It looks like Notify is nil when GetImagePath is executed.

I added fmt.Println(Notify) here and this is what I see.

$ go build && ./gomp
<nil>

Unfortunately, I have very little experience with Go, otherwise, I'd try to troubleshoot further.

Some further information. I'm running on macOS and building from source. I'm using Kitty and not really expecting imagine rending to work at this point.

I'm running gomp on a pretty powerful machine, yet with a larger playlist of over 1k entries the TUI feels awfully sluggish. Pressing arrow down for a few seconds and letting it go makes the selection continue to advance for several seconds before it stops.

If you're using Arch Linux, here's how i build package

pkgname=goMP
pkgver=0.1
pkgrel=1
pkgdesc='MPD client inspired by ncmpcpp written in GO.'
arch=('any')
url="https://github.com/aditya-K2/goMP"
license=('GPL')
depends=('go')
makedepends=('go')
source=("https://github.com/aditya-K2/goMP/archive/refs/heads/master.zip")
sha256sums=('SKIP')

build() {
    cd "${pkgname}-master"
    go build
}

package() {
    cd "${pkgname}-master"
    install -Dm 655 goMP -t "${pkgdir}/usr/bin"
}

Gomp should look at the $XDG_CONFIG_HOME environment variable for where to place its configuration file. More information: https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html/#basics

Hey all,

Gomp looks supremely awesome and I would love to use it, but I don't run mpd anymore and have moved to gonic for music streaming server I'm not sure how difficult it would be, or whether you'd want to support this, so this is just a suggestion :)
