allows Emacs Ido to use the flx sorting algorithm
The flx sorting algorithm for Emacs provides fuzzy matching for completion engines like Ido. It is similar to the fuzzy matching functionality of Sublime Text. . The user can input (i) characters from the beginning of the words of the desired match and (ii) substrings of the desired match. For example, when matching "save-all-buffers", the user could input "sallb", and when matching "eval-buffer" the user could input "ebuffer". . The flx sorting algorithm implements an intelligent trade-off between word beginnings and contiguous substrings when ranking possible matches. . This package allows Emacs Ido to use the flx sorting algorithm.
