Answer 1

After a few hours of hard work, I found the answer.
It's the matchai/spacefish plugin which add new line to my prompt.
Here is the function
# Defined in /Users/liwei/.config/fish/functions/fish_prompt.fish # line 1
function fish_prompt
set -g sf_exit_code $status
set -g SPACEFISH_VERSION 2.6.0
# ------------------------------------------------------------------------------
# Configuration
# ------------------------------------------------------------------------------
__sf_util_set_default SPACEFISH_PROMPT_ADD_NEWLINE true
__sf_util_set_default SPACEFISH_PROMPT_FIRST_PREFIX_SHOW false
__sf_util_set_default SPACEFISH_PROMPT_PREFIXES_SHOW true
__sf_util_set_default SPACEFISH_PROMPT_SUFFIXES_SHOW true
__sf_util_set_default SPACEFISH_PROMPT_DEFAULT_PREFIX "via "
__sf_util_set_default SPACEFISH_PROMPT_DEFAULT_SUFFIX " "
__sf_util_set_default SPACEFISH_PROMPT_ORDER time user dir host git package node ruby golang php rust haskell julia elixir docker aws venv conda pyenv dotnet kubecontext exec_time line_sep battery vi_mode jobs exit_code char
# ------------------------------------------------------------------------------
# Sections
# ------------------------------------------------------------------------------
# Keep track of whether the prompt has already been opened
set -g sf_prompt_opened $SPACEFISH_PROMPT_FIRST_PREFIX_SHOW
if test "$SPACEFISH_PROMPT_ADD_NEWLINE" = "true"
echo
end
for i in $SPACEFISH_PROMPT_ORDER
eval __sf_section_$i
end
set_color normal
end
Just set SPACEFISH_PROMPT_ADD_NEWLINE to false,
add this line to your config.fish and solve the problem.
set SPACEFISH_PROMPT_ADD_NEWLINE false
Thanks to all.
