C-M-a and C-M-e

[immerrr]

It should bring you to the beginning of line containing a header (or a footer, so to speak, if C-M-e was pressed) of top-level function. If you want to jump out of "{}" or "()" you are better off with backward-up-alist (C-M-u).

[immerrr]

It's an open question though if it should bring you to the beginning of non-toplevel function if you're inside one, i.e.

function foo()
   return function ()
      return 'bar' 
   end
end

if point is on 'bar' is it the inner or the outer function to skip to. I need to skim through the code to see the impact of this change.

I'd prefer going to line 2, and then line 1 in your example, when pressing C-M-a, but I'm not sure what the conventional way is.

Ok, I've refreshed this in my memory and it is an Emacs convention: according to the manual C-M-a and C-M-e should move point ... based on top-level major definitions, also called defuns.

It means that lua-mode works as expected and therefore I'm closing the issue. But, making backward-up-list (C-M-u) work with function and control blocks is a valid point and must be done eventually. I always thought smartparens is capable of that, but I'm not sure if library integration is within lua-mode's scope.
