How can I make eza default in preview-tui?

[nemonein]

Hi.
The plugin preview-tui chooses tree as the first option.
I'd like to use exa(eza) over tree, but I don't see any option for that.
Do I have to edit the source(plugins/preview-tui) directly?
-- removing tree related lines?? OR move up eza over tree?

Not possible it seems, we only have USE_ICONLOOKUP for directory preview. Should probably merge that into something like NNN_PREVIEWDIRPROG, anologous to NNN_PREVIEWIMGPROG. For now your only option is to edit the plugin yes.

Plugins are samples, supposed to be edited and adapted by users as per their needs.

Thank you for your replies.
I hope this should be documented somewhere.
--> Plugins are samples, so users have to modify the plugins to get a specific result.

I use eza with preview-tui, works well. This is what I modified, starting line 342. Modify line 352 according to what you'd like to be displayed.

    # Otherwise, falling back to the defaults.
    if [ -d "$1" ]; then
        cd "$1" || return
        if [ "$NNN_ICONLOOKUP" -ne 0 ] && [ -f "$(dirname "$0")"/.iconlookup ]; then
            [ "$NNN_SPLIT" = v ] && BSTR="\n"
            # shellcheck disable=SC2012
            ls -F --group-directories-first | head -n "$((lines - 3))" | "$(dirname "$0")"/.iconlookup -l "$cols" -B "$BSTR" -b " "
        elif exists tree; then
            fifo_pager tree --filelimit "$(find . -maxdepth 1 | wc -l)" -L 3 -C -F --dirsfirst --noreport
        elif exists eza; then
            eza -l --group-directories-first --colour=always --no-permissions --no-user   
        else
            fifo_pager ls -F --group-directories-first --color=always
        fi
        cd ..
    elif [ "${encoding#*)}" = "binary" ]; then
        handle_mime "$1" "$mimetype" "$ext" "bin"
    else
        handle_mime "$1" "$mimetype" "$ext"
    fi
}
