问题#

在 VSCode 内打开 Terminal：

• 输入会在 prompt 下一行
• 但是在 source ~/.config/fish/config.fish 后，输入会紧跟 prompt
• 仅在 VSCode 出现该问题

如下：

~/p/flutter_server_box main! >
source $FIC
~/p/flutter_server_box main! > code $FIC
~/p/flutter_server_box main! >

原因#

echo -e 会在 VSCode Terminal 中异常换行

function fish_prompt
    echo -e "$_hydro_color_pwd$_hydro_pwd$hydro_color_normal $_hydro_color_git$$_hydro_git$hydro_color_normal$_hydro_color_duration$_hydro_cmd_duration$hydro_color_normal$_hydro_status$hydro_color_normal "
end

解决#

将 echo -e 替换为 printf，使用更加精确的格式化输出

function fish_prompt
    printf '%s%s%s %s%s%s%s%s%s%s%s ' \
        "$_hydro_color_pwd" "$_hydro_pwd" "$hydro_color_normal" \
        "$_hydro_color_git" "$$_hydro_git" "$hydro_color_normal" \
        "$_hydro_color_duration" "$_hydro_cmd_duration" "$hydro_color_normal" \
        "$_hydro_status" "$hydro_color_normal"
end
