Not working!

[frnogueira]

Hi! lf-ueberzug only work in the git directory. When I put the files in /usr/bin, create the alias in .zshrc, the lf-ueberzug not using the lfrc file, and the previews not working. What the solution for this? Thanks!

Hi! I suppose you want to use ueberzug previewes in addition to your existing lf configuration (because this lf-ueberzug gadget really is good for nothing but to demonstrate ueberzug previews). To achieve that you simply

• delete anything related to lf-ueberzug that you installed prior
• copy lf-ueberzug-cleaner to /usr/local/bin
• copy lf-ueberzug-previewer to /usr/local/bin
• Add the following to your ~/.config/lf/lfrc file (create it, if it doesn't exist)

  set previewer lf-ueberzug-previewer
  set cleaner lf-ueberzug-cleaner

• Add the following to your .zshrc

  lf-ueberzug() {
  cleanup() {
      lf-ueberzug-cleaner
      kill "$UEBERZUGPID"
      pkill -f "tail -f $LF_UEBERZUG_TEMPDIR/fifo"
      rm -rf "$LF_UEBERZUG_TEMPDIR"
  }
  trap cleanup INT HUP
  
  # Set up temporary directory.
  export LF_UEBERZUG_TEMPDIR="$(mktemp -d -t lf-ueberzug-XXXXXX)"
  
  # Launch ueberzug.
  mkfifo "$LF_UEBERZUG_TEMPDIR/fifo"
  tail -f "$LF_UEBERZUG_TEMPDIR/fifo" | ueberzug layer --silent &
  UEBERZUGPID=$!
  
  lf "$@"
  cleanup
  }
  alias lf=lf-ueberzug

Does this answer your question?

I'm having a similar issue to op. I followed your instructions and added to the .zshrc, but no image previews still. I get this after closing lf

$ lf
[2] 4970 4971
removed '/tmp/lf-ueberzug-HI3Rw0/fifo'
removed directory '/tmp/lf-ueberzug-HI3Rw0'
$
[2]  + terminated  tail -f "$LF_UEBERZUG_TEMPDIR/fifo" |
       done        ueberzug layer --silent

Does this only work with specific terminals? I'm using suckless' st.

Hi @Skrib. It's supposed to be terminal-agnostic and I'm also using st.

Let's check a few other things (some of the answers can be deduced from the fact that you use st, but let's make sure we're on the same page :wink:)

• What's your ueberzug version?
• You're running a Linux, correct? I realize that this should have been communicated more clearly: ueberzug is made for X11-environments on Linux and won't work for anything else.
• You're running a GNU/Linux, correct? This should be irrelevant, but there may be subtle differences in the GNU-flavors of coreutils that I'm unaware of which are biting you in the arse.

• Do ueberzug previews work in principle on your machine? This snippet should generate an overview inside the terminal if run by zsh or bash.

  curl -Lso - "$imgurl" > dog.jpg
  
  # Start ueberzug daemon
  mkfifo ueberzug_fifo
  tail -f ueberzug_fifo | ueberzug layer -p json &
  
  # Create an overlay
  cat <<<'{ "action": "add", "identifier": "ueberzug-preview", "path": "dog.jpg", "x": 0, "y": 0, "width": 20, "height": 16, "scaler": "contain" }' >ueberzug_fifo

Thanks for the response, but I've got it working now.

I had to reinstall Linux because of some driver issues. When I tried implementing your first post in this thread again, I wasn't getting any errors, it just wasn't working. But commenting this line I had in lfrc fixed it: # Vars that depend on environmental variables $lf -remote "send $id set previewer ${XDG_CONFIG_HOME:-$HOME/.config}/lf/scope" I'm assuming the original errors were from my poor implementing of some other lf code. Sorry for the hassle and thanks agian! This works great now and is very useful.
