FISH_MODE_PROMPT(1)

NAME
fish_mode_prompt - define the appearance of the mode indicator

SYNOPSIS
fish_mode_prompt

    function fish_mode_prompt
         echo -n "$fish_bind_mode "
    end

DESCRIPTION

The fish_mode_prompt function outputs the mode indicator for use in vi mode.

The default fish_mode_prompt function will output indicators about the current vi editor mode displayed to the left of the regular prompt. Define your own function to customize the appearance of the mode indicator. The $fish_bind_mode variable can be used to determine the current mode. It will be one of default, insert, replace_one, replace, visual, or operator.

You can also define an empty fish_mode_prompt function to remove the vi mode indicators:

    function fish_mode_prompt; end
    funcsave fish_mode_prompt

fish_mode_prompt will be executed when the vi mode changes. If it produces any output, it is displayed and used. If it does not, the other prompt functions (fish_prompt <> and fish_right_prompt <>) will be executed as well in case they contain a mode display.

If fish_transient_prompt <#envvar-fish_transient_prompt> is set to 1, fish_mode_prompt --final-rendering is run before executing the commandline.

EXAMPLE

    function fish_mode_prompt
      switch $fish_bind_mode
        case default
          set_color --bold red
          echo 'N'
        case insert
          set_color --bold green
          echo 'I'
        case replace_one
          set_color --bold green
          echo 'R'
        case replace
          set_color --bold bryellow
          echo 'R'
        case visual
          set_color --bold brmagenta
          echo 'V'
        case operator f F t T
          set_color --bold cyan
          echo 'N'
        case '*'
          set_color --bold red
          echo '?'
      end
      set_color --reset
    end

Outputting multiple lines is not supported in fish_mode_prompt.
