wishlist: completion, function argument hints

[tpapp]

It would be nice to have

1. completion for functions (mostly distributions),
2. some kind of hints that could either be shown with a command, or automatically, in the minibuffer or as a popup hint. For example, for normal(...) it would display something like normal(mu, sigma). Since STAN sometimes uses different semantics for functions that are also present in R etc (eg in R the normal uses variance), this could help prevent some coding errors.

I don't know how to implement these features in Emacs, but once a framework is in place, I would be happy to fill it in the actual definitions.

I very much agree. So much, so that I've incorporated auto-completing using ac-mode and yasnippet in the development branch. I just haven't merged it into the main branch. Try using the develop branch and let me know how it works for you.

I could not use it, I get the following debug trace when I try to open a file:

Debugger entered--Lisp error: (void-variable stan--load-ac)
  (if stan--load-ac (progn stan-ac-mode-setup))
  stan-mode()
  set-auto-mode-0(stan-mode nil)

Sorry about that. I just fixed it in the current devel commit.

autocomplete features using ac-mode and yasnippet are now included in the package.
