Here the last version of eldoc-eval.el.
It provide a new macro `with-eldoc-in-minibuffer' that allow to enable
eldoc support in any minibuffer code:

(with-eldoc-in-minibuffer (read-string "test eldoc: " "(let")))

It also follow arguments while you are writing, just like normal eldoc.
To see this, you need to set a visible face, the default one of eldoc is
most of the time invisible, do like this or use customize:

(when (require 'eldoc)
  (set-face-attribute 'eldoc-highlight-function-argument nil :underline "red"))
