Show xattributes in promptfmt?

[MarcCoquand]

Heya,

I'm trying to display some custom xattribuets in the prompt. I've set up the following previewer:

#!/usr/bin/env sh

categories=$(getfattr -n user.categories --only-values "$1")
lf -remote "send $id set promptfmt \"%d $f\""

case "$(file -Lb --mime-type -- "$1")" in
  text/*)
    case "$1" in
        *.md)
            pandoc -f markdown -t plain "$1"
            ;;
        *)
            cat "$1"
            ;;
    esac
    ;;
esac

However, I'm noticing that it doesn't seem to correctly update on each file change. It seems like the previews maybe get cached? Am I doing this right?

The result of the previewer script is cached if it exits successfully (return code of 0), so it won't be run again.

If you want to run something whenever a new file is selected, it is better to define the on-select hook command instead:

cmd on-select &{{
    # replace the contents of `$(ls -l -d "$f")` with whatever you need
    lf -remote "send $id set promptfmt \"$(ls -l -d "$f")\""
}}

Wonderful, this ended up working: ``` cmd on-select &{{ lf -remote "send $id set promptfmt \"%d $(getfattr -n user.categories --only-values "$f")\"" }} ``` Cheers, Marc
