Ddc.vim filter which uses edit distance for matching and sorting candidates.

https://github.com/vim-denops/denops.vim

https://github.com/Shougo/ddc.vim

It removes candidates which has greater edit distance than threshold. This also sorts candidates by editdistance.

It only sort candidates by edit distance. I recommend using only matcher_editdistance.

• limit: (number) Candidates whose edit distance exceed this value are ignored. (default: 3)
• diffLen: (number) If candidates' length is smaller than (users' input + params.diffLen), the candidates are ignored. (default: -1)
• showScore: (boolean) If it is true, edit distance is shown in completion menu. (default: false)

call ddc#custom#patch_global('sourceOptions', {
      \ '_': {'matchers': ['matcher_editdistance'], 'sorters': []},
      \ })

call ddc#custom#patch_global('filterParams', {
      \ 'matcher_editdistance': {'showScore': v:true, 'diffLen': 0, 'limit': 2},
      \ })
