# ViFM
|
||||
|
||||
[ViFM](https://vifm.info) is a file manager focussed on vim like usage.
|
||||
|
||||
## Image Previews with Ueberzug
|
||||
|
||||
This section is based on a
|
||||
[video by Distrotube](https://www.youtube.com/watch?v=qgxsduCO1pE).
|
||||
First you need to install [Ueberzug](https://github.com/seebye/ueberzug)
|
||||
on your system.
|
||||
After that you need to add 2 files to your path:
|
||||
|
||||
- vifmimg
|
||||
- vifmrun
|
||||
|
||||
If you want to preview files vifmrun you will start vifmrun instead of vifm.
|
||||
|
||||
vifmrun:
|
||||
|
||||
```sh
|
||||
#!/usr/bin/env bash
|
||||
|
||||
# by cirala, checkout github.com/cirala/vifmimg
|
||||
|
||||
export FIFO_UEBERZUG="/tmp/vifm-ueberzug-${PPID}"
|
||||
|
||||
if [ ! -f "/usr/bin/ueberzug" ]; then
|
||||
vifm
|
||||
exit
|
||||
fi
|
||||
|
||||
function cleanup {
|
||||
rm "$FIFO_UEBERZUG" 2>/dev/null
|
||||
pkill -P $$ 2>/dev/null
|
||||
}
|
||||
pkill -P $$ 2>/dev/null
|
||||
rm "$FIFO_UEBERZUG" 2>/dev/null
|
||||
mkfifo "$FIFO_UEBERZUG" >/dev/null
|
||||
trap cleanup EXIT 2>/dev/null
|
||||
tail --follow "$FIFO_UEBERZUG" | ueberzug layer --silent --parser bash 2>&1 >/dev/null &
|
||||
|
||||
vifm "$@"
|
||||
cleanup
|
||||
```
|
||||
|
||||
vifmimg:
|
||||
|
||||
```sh
|
||||
#!/usr/bin/env bash
|
||||
readonly ID_PREVIEW="preview"
|
||||
|
||||
#PLAY_GIF="yes"
|
||||
# By enabling this option the GIF will be animated, by leaving it commented like it
|
||||
# is now will make the gif previews behave the same way as video previews.
|
||||
|
||||
#AUTO_REMOVE="yes"
|
||||
# By enabling this option the script will remove the preview file after it is drawn
|
||||
# and by doing so the preview will always be up-to-date with the file.
|
||||
# This however, requires more CPU and therefore affects the overall performance.
|
||||
|
||||
# The messy code below is for moving pages in pdf files in the vifm file preview by
|
||||
# utilizing the < and > keys which will be bound to `vifmimg inc` or `vifmimg dec`.
