Hi folks, I really got used to using emacs ido mode, which offers a pretty powerful and intuitive fuzzy matching of completions, so I wanted to port the same to XMonad.Prompt. This required two patches, included in the attached patch bundles: (1) Completions should be sortable by how well they match the current query string. This turned out to be a very easy addition of a 'sorter' function to XPConfig, which is parameterized by the current query string. The default is 'const id', that is, no sorting is done, which is exactly the old behaviour of XMonad.Prompt. (2) A new module XMonad.Prompt.FuzzyMatch that implements the fuzzy matching. The exact rules for matching and sorting of matches are explained in its documentation. As usual, let me know if anything needs to straightened out before these patches can be applied. Cheers, Norbert
