Instead of going only in the order of "for suggestion in suggestions:", retain the implied rank of the order of suggestion types, and the fuzziness of the match from find_matches(), and sort by all of fuzziness, rank, and leading match. Primarily this allows the fuzzy matches to always be demoted to the bottom of the list of candidates. The sort-key algorithm takes into account fuzziness, suggestion-rank, and leading-match, but how exactly depends on whether the completion string is empty, or the completion string is a leading match. To implement this, sorting must be moved out of find_matches(). A special case "rigid_sort" is provided so that directories continue to be forced to last in filename sorts. This could be improved in the future.

There was a problem hiding this comment.
Nice that was a lot to tie together! Verified completions with more exact matches seem to come back first now for normal / camel case / snake case columns and functions/keywords.

Description
Instead of going only in the order of
for suggestion in suggestions:, retain the implied rank of the order of suggestion types, and the fuzziness of the match fromfind_matches(), and sort by all of fuzziness, rank, and leading match.Primarily this allows the fuzzy matches to always be demoted to the bottom of the list of candidates.
The sort-key algorithm takes into account fuzziness, suggestion-rank, and leading-match, but how exactly depends on whether the completion string is empty, or the completion string is a leading match.
To implement this, sorting must be moved out of
find_matches().A special case
rigid_sortis provided so that directories continue to be forced to last in filename sorts. This could be improved in the future.The motivation is to make #1497 more able to combine column names and keywords.
The tests are pretty broken in this draft, part of which is expected.fixed.Checklist
