Here is the most valuable part of my emacs vTerm config with fish shell.
add source vterm.fish to your fish shell configuration file
use edit <file> in vTerm buffer will open file at the new window above vTerm buffer, similar to using code <file> in VSCode embedded terminal.
vterm.fish

function vterm_printf
if begin
[ -n "$TMUX" ]; and string match -q -r "screen|tmux" "$TERM"
end
# tell tmux to pass the escape sequences through
printf "\ePtmux;\e\e]%s\007\e\\" "$argv"
else if string match -q -- "screen*" "$TERM"
# GNU screen (screen, screen-256color, screen-256color-bce)
printf "\eP\e]%s\007\e\\" "$argv"
else
printf "\e]%s\e\\" "$argv"
end
end
function vterm_cmd --description 'Run an Emacs command among the ones been defined in vterm-eval-cmds.'
set -l vterm_elisp ()
for arg in $argv
set -a vterm_elisp (printf '"%s" ' (string replace -a -r '([\\\\"])' '\\\\\\\\$1' $arg))
end
vterm_printf '51;E'(string join '' $vterm_elisp)
end
if [ "$INSIDE_EMACS" = vterm ]
set -gx EDITOR code
function clear
vterm_printf "51;Evterm-clear-scrollback"
tput clear
end
# used by vterm buffer name
function fish_title
hostname
echo ":"
prompt_pwd
end
function vterm_prompt_end --on-variable PWD
vterm_printf '51;A'(whoami)'@'(hostname)':'(pwd)
end
function edit
set -q argv[1]; or set argv[1] "."
vterm_cmd vterm-edit-file (realpath "$argv")
