show list of options in elisp

Question

HI,

I have the following problem:

Provided a list of values, and using a formatting function passed as argument, display all its elements in a helper buffer. The user would then select one of them using the arrow keys. The returned value must be the chosen entry.

If you have ever used reftex to insert citations, or browse-kill-ring, you know what I'm talking about. Those two examples use custom code to achieve the desired results, but perhaps there is a library that could do that.

Answer 1

(with-output-to-temp-buffer "*Name of buffer*"
  (display-completion-list '("foo" "bar" "baz" "qux")))
