Set shell interpreter seems not working for integrations about lf HOT 4 OPEN

I'm guessing you have sh linked to fish, so with the default setting set shell sh, all shell commands will be interpreted by fish. If you want to use a different shell within lf, then just configure something like set shell bash.

@joelim-work Thanks for your replay. I don't have a linked sh for fish. But even I have a linked sh for fish maybe the better way is using the absolute path for this shell interpreter.

set shell bash

cmd rg_search ${{
    res="$( \
        RG_PREFIX="rg --column \
            --hidden \
            --line-number \

            startline=\$([ \$currentline -ge 50 ] && expr \$currentline - 50 || expr 0)
            endline=\$(expr \$currentline + 50)

            fzf --bind "change:reload:$RG_PREFIX {q} || true" \
            --ansi --header 'Search in files' \
            --preview "$preview" \
            | cut -d':' -f1
    )"
    [ ! -z "$res" ] && lf -remote "send $id select \"$res\""
}}
map fs :rg_search

I use chsh to switch shell and test the case.
When I switched to zsh works fine, while with fish shell failed and show the top error. Not test for bash.

When executing shell commands (e.g. map x $var=123; echo "$var"), lf uses the shell that's configured using set shell ....

Your login shell (set using chsh) is not relevant here.

Here is a more minimal config example:

set shell bash
# set shell fish
# set shell zsh

map x $var=123; echo "$var"

For me set shell bash and set shell zsh work, but set shell fish doesn't, which is what I would expect since var=123 isn't valid syntax in fish.

I am facing the same issue with integrations for my fish shell even though I have set shell fish
I found it works when I convert the integration to compatible with fish
