Enhanced Image Preview in Vifm with Ueberzug
A Guide to Implementing Robust Image and Media Previews in Vifm with Proper Cache Handling and Preview Cleanup
This enhancement improves the original vifmimg script by adding cache management and fixing preview persistence issues.
Rationale Behind All This
As a Vim enthusiast, I always wanted to replicate my daily workflow based on keymappings and completely avoid using the mouse. I missed the functionality offered by tools like in Vifm, but I didn't want to learn a whole new set of keyboard shortcuts. I watched several YouTube videos trying to recreate this setup, but none quite hit the mark. The project that inspired this work didn't fully meet its intended functionality.
After spending many sleepless nights struggling with it, I have finally achieved something that feels rewarding, at least to me, and I want to share it with you.
I have currently verified these configurations only on Arch Linux"
Prerequisites
Ensure you have these packages installed:
- vifm
- ueberzug
- ffmpegthumbnailer
pdftoppm (from poppler-utils)- epub-thumbnailer
djview (for DJVU documents)- ffmpeg
- fontpreview
- imagemagick
Packages Installation for Arch Linux
# Install required packages
sudo pacman -S vifm ueberzug ffmpegthumbnailer poppler djvulibre imagemagick
# Install fontpreview using AUR helper
yay -S fontpreview
Follow the instructions in .
Installation Steps
1. Get Original Scripts
Create the scripts directory and download the original scripts:
# Create scripts directory
mkdir -p ~/.config/vifm/scripts
# Download original scripts
wget -P ~/.config/vifm/scripts/ https://raw.githubusercontent.com/thimc/vifmimg/master/vifmimg
wget -P ~/.config/vifm/scripts/ https://raw.githubusercontent.com/thimc/vifmimg/master/vifmrun
2. Implement Enhanced vifmimg Script
Replace the content of ~/.config/vifm/scripts/vifmimg with the improved version below. This version includes proper cache handling and fixes preview persistence issues:
#!/usr/bin/bash
# Cache directory
CACHE_DIR="$HOME/.cache/vifm"
mkdir -p "$CACHE_DIR"
PCACHE="$CACHE_DIR/thumbnail.$(stat --printf '%n\0%i\0%F\0%s\0%W\0%Y' -- "$(readlink -f "$PWD/$6")" | sha256sum)"
export PCACHE="${PCACHE%% *}"
# Clear ueberzug preview
pclear() {
printf '{"action": "remove", "identifier": "vifm-preview"}\n' >"$FIFO_UEBERZUG"
}
# Display image using ueberzug
image() {
printf '{"action": "add", "identifier": "vifm-preview", "x": "%s", "y": "%s", "width": "%s", "height": "%s", "scaler": "contain", "path": "%s"}\n' \
"$2" "$3" "$4" "$5" "$6" >"$FIFO_UEBERZUG"
}
main() {
case "$1" in
"clear")
pclear "$@"
;;
"draw")
FILE="$PWD/$6"
image "$1" "$2" "$3" "$4" "$5" "$FILE"
;;
"video")
FILE="$PWD/$6"
[ ! -f "${PCACHE}.jpg" ] &&
ffmpegthumbnailer -i "$FILE" -o "${PCACHE}.jpg" -s 0 -q 5
image "$1" "$2" "$3" "$4" "$5" "${PCACHE}.jpg"
;;
"epub")
FILE="$PWD/$6"
[ ! -f "$PCACHE" ] &&
epub-thumbnailer "$FILE" "$PCACHE" 1024
image "$1" "$2" "$3" "$4" "$5" "$PCACHE"
;;
"pdf")
FILE="$PWD/$6"
[ ! -f "${PCACHE}.jpg" ] &&
pdftoppm -jpeg -f 1 -singlefile "$FILE" "$PCACHE"
image "$1" "$2" "$3" "$4" "$5" "${PCACHE}.jpg"
;;
"djvu")
FILE="$PWD/$6"
[ ! -f "${PCACHE}.jpg" ] &&
ddjvu -format=tiff -quality=90 -page=1 "$FILE" "${PCACHE}.jpg"
image "$1" "$2" "$3" "$4" "$5" "${PCACHE}.jpg"
;;
"audio")
FILE="$PWD/$6"
[ ! -f "${PCACHE}.jpg" ] &&
ffmpeg -hide_banner -i "$FILE" "${PCACHE}.jpg" -y >/dev/null
image "$1" "$2" "$3" "$4" "$5" "${PCACHE}.jpg"
;;
"font")
FILE="$PWD/$6"
[ ! -f "${PCACHE}.jpg" ] &&
fontpreview -i "$FILE" -o "${PCACHE}.jpg"
image "$1" "$2" "$3" "$4" "$5" "${PCACHE}.jpg"
;;
*)
# Clear preview for any unhandled file types
pclear
;;
esac
}
main "$@"
3. Make Scripts Executable and Accessible
Choose one of these methods:
Option A: Link to /usr/local/bin (Recommended)
# Make scripts executable
chmod +x ~/.config/vifm/scripts/vifmrun
chmod +x ~/.config/vifm/scripts/vifmimg
# Create symbolic links
sudo ln -s ~/.config/vifm/scripts/vifmrun /usr/local/bin/
sudo ln -s ~/.config/vifm/scripts/vifmimg /usr/local/bin/
Option B: Add to PATH
Add the following line to your ~/.bashrc or ~/.zshrc:
export PATH=$PATH:$HOME/.config/vifm/scripts
# Reload shell configuration
source ~/.bashrc # or source ~/.zshrc for zsh users
4. Configure Vifm
Add these lines to your ~/.config/vifm/vifmrc to enable file previews:
" Add a command to force clean thumbnails
command! clearthumb ! vifmimg force-clean
" ------------------------------------------------------------------------------
" File preview settings with vifmimg

This is only the configuration for previewing images, you also need to add these configurations down below to open them:
" Pdf

These are examples of my file associations, which you can modify to open files according to your preferences by installing the applications of your liking. There is a subtle difference between filetype and filextype:
- filetype is used for console-based applications
- filextype is used for graphical applications
Depending on the file type, you'll need to download the required binaries if they aren't already present.
