We previously checked if fish_mode_prompt existed as a function, but that's a bad change for those who already set it to an empty function to have a mode display elsewhere.

fish_mode_prompt - define the appearance of the mode indicator
|
|
==============================================================
|
|
|
|
|
|
|
|
The fish_mode_prompt function will output the mode indicator for use in vi-mode.
|
|
|
|
Description
|
|
-----------
|
|
|
|
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. You can also define an empty ``fish_mode_prompt`` function to remove the Vi mode indicators. The ``$fish_bind_mode variable`` can be used to determine the current mode. It
|
|
will be one of ``default``, ``insert``, ``replace_one``, or ``visual``.
|
|
|
|
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 (:ref:`fish_prompt <cmd-fish_prompt>` and :ref:`fish_right_prompt <cmd-fish_right_prompt>`) will be executed as well in case they contain a mode display.

|
|
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 visual
|

set_color --bold brmagenta

echo 'V'

set_color --bold red
|

echo '?'
|
