Adds synopses for those commands missing them. Moves all synopsis sections to code blocks. This improves the appearance, although highlighting as fish code may not be the ideal appearance.

Synopsis
|
|
--------
|
|
|
|
::
|
|
|
|
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. 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.
