The computing environments I prefer are minimal. Minimal window managers, and CLI oriented programs are my preference. This being the case, I am not a fan of xdg-open. This may be because I dont fully understand it, or because I feel it is overly complex. Whatever the reason, I prefer a plumber which is explicity defined, in a language I can understand.
The Noice terminal file manager relies on a separate opener for plumbing called 'nopen'. File types, and what those file types are opened with is explicitly defined. I find this appealing. The same kind of opener can be created using posix shell with a case statement:
case $1 in
*.mp4|*.mkv|*.webm|*.mov|*.m3u)
mpv "$1"
;;
*.ogg|*.mp3|*.pls*|*.opus|*.aiff|*.aif|*.flac)
mpv --no-video "$1"
;;
*.png|*.gif|*.jpg|*.jpe|*.jpeg|*.webp)
nsxiv "$1"
;;
*.html|*.htm)
w3m "$1"
;;
*.pdf|*.epub|*.cbz|*.djvu)
zathura "$1"
;;
*.md)
lowdown -Tterm "$1" | less
;;
# all other files
*)
"${EDITOR:=vi}" "$1"
;;
esac
I use this opener for almost everything now, and added it to my
system in the following ways:
In ~/bin/openr.sh
Added to my ~/.kshrc as:
openr(){
"the above case statement"
}
map o $openr $f
cmd openr $/home/atyh/bin/openr.sh $f
OPENER=/home/atyh/bin/openr.sh
With the opener(plumber) defined in these 4 locations, I am able to
use it to great effect. The power in this lies in the ability to
define shell commands for specific file types. The *.md) section for
example takes advantage of lowdown(1)'s ability to format markdown
documents into terminal formated output. With this, in lf, I can
push 'o' and lf will open a README.md in a git repo in a nice color
formated and readable way in less(1).
This is really just scratching the surface with what can be done
with this plumbing method.
