how to get fish to stay in dir the same way you can in bash with this function? (does not work in fish)

[emilBeBri]

Hey so just starting using fish, and the following which worked fine in bash:

llf () {
    tmp="$(mktemp)"
    lf -last-dir-path="$tmp" "$@"
    if [ -f "$tmp" ]; then
        dir="$(cat "$tmp")"
        rm -f "$tmp"
        if [ -d "$dir" ]; then
            if [ "$dir" != "$(pwd)" ]; then
                cd "$dir"
            fi
        fi
    fi
}
alias lf=llf

does not work in fish - I tried fixing (fishing?) it, but I could not. Perhaps someone who knows fish could fix it and add it to the 'integrations' page? thank you.

Have you seen https://github.com/gokcehan/lf/blob/master/etc/lfcd.fish? You are welcome to link to it from the wiki.

ah yes thanks - I have added it to the wiki, but I'd like to add an alias so that lfcd will takeover lf, just like in bash.

However, doing that breaks things and I get this output:

in function 'lfcd' with arguments '-last-dir-path=/tmp/tmp.8PItZC3tgR -last-dir-path=/tmp/tmp.1wJPT6GcEy -last-dir-path=/tmp/tmp.G5mhsAVAlI -last-dir-path=/tmp/tmp.56YnOa9onE -last-dir-path=/tmp/tmp.QaOgaZQES5'

any idea what's going on here? It would be a shame that lf coulnd't be used with this functionality in fish with the original name.

also, if I may disturb you just a little bit longer, what does this command do, that is suggested? I fail to see it.

# You may also like to assign a key to this command:
#
#     bind \co 'set old_tty (stty -g); stty sane; lfcd; stty $old_tty; commandline -f repaint'

To fix your alias, you need to replace lf -last-dir-path=$tmp $argv by command lf -last-dir-path=$tmp $argv in the fish script.

The bind \co line would make Ctrl-O open lfcd in the fish prompt. This even allows you to change the current directory in the middle of typing a command.

I will hopefully make a PR to incorporate both of these things into the scripts at some point.
