Greetings

Currently, fish-contextual-greeting supports the following greeting contexts:

greeting_for_ssh: When connected through a SSH client.

function greeting_for_ssh
	if contextual_greeting --is-toplevel  # only show if it's not a nested shell
		echo "Hello, $SSH_CLIENT!"
	end
end

greeting_for_ide: When using an IDE terminal.

function greeting_for_ide
	echo "You appear to be using an IDE terminal."
end

greeting_for_tmux: When inside a tmux pane.

function greeting_for_tmux
	tmux list-windows
end

The user's fish_greeting will also be called after the other contextual greetings..

Configuration

Greetings can be configured with variables:

Variable	Default	Description
contextualgreeting_order	'ssh' 'ide' 'tmux' 'fish'	The order in which prefixes are printed.
contextualgreeting_prefix	'greeting_for_'	The prefix for greeting functions.
contextualgreeting_redraw	false	Redraw the greeting if the terminal is resized.

Advanced Features

Event Listener

You can add an event listener for the contextual_greeting event to optionally disable greetings under certain circumstances:

function disable_ide_message_for_tmux --on-event contextual_greeting
	set -l current_context $argv[1]
	if contains "tmux" (contextual_greeting contexts) && test $current_context = "ide" 
		contextual_greeting skip
	end
end
