27 ;; This package provides `ivy-read' as an alternative to
28 ;; `completing-read' and similar functions.
30 ;; There's no intricate code to determine the best candidate.
31 ;; Instead, the user can navigate to it with `ivy-next-line' and
32 ;; `ivy-previous-line'.
34 ;; The matching is done by splitting the input text by spaces and
35 ;; re-building it into a regex.
36 ;; So "for example" is transformed into "\\(for\\).*\\(example\\)".
