Provide an interface to get current_state

[guoang]

I'm trying to write my own theme and need this interface.

diff --git a/lua/alpha.lua b/lua/alpha.lua

+end

 alpha.layout_element = layout_element
 alpha.keymaps_element = keymaps_element

i believe lua tables are passed by reference so alpha.current_state = current_state would suffice, can i ask what you're trying to do? just out of curiosity

This looks good to me too. What I need is to access current_state in my vim config, I currently can't do that since current_state is a local variable.

[goolord]

the reason i'm asking what specifically you're trying to do is because you can already access the state by extending the layout_element and keymaps_element tables which is a bit more principled. if you're not actually defining a new element type then i'm curious y you need the state.

also the api just changed a little to accommodate multiple concurrent alpha configs

but this could still be done

@goolord for context I'm looking into this too, the reason I want the state available would be because when I open a new session I want to be able to say "If and only if alpha is not already open, open alpha", since the start command also closes alpha and is more of a toggle. Alternatively, making start idempotent would also work
