Please don't use getline() in source.
It does not work in command line.

bug: cannot use matcher other than matcher_head

my japanese brain dump

matcher_head 互換のフィルターしか使えず、かつ、matcher_head 相当の機能しか提供できない

#4 を考慮する必要がある

matcher は search(input) が matched の 部分列 (sub sequence) であることは多分仮定していい。 (matcher_reversed のようなものは現実的に意味がない)
これに加えてもう一つ仮定を加えるとおそらく対処法がある。
「 ∀a, a',b,c; match(a+b, a'+c) && match(a, a') ⇒ match(b, c)」とかだと思う。（要検討）

もしくは matcher_head 以外サポートしないか。

EDIT:

now we can use only matcher_head like behavior even if setting matchers.
it is fixed by sending all filenames.

we should take care about #4, but it can be resolved by sending with cutting common-prefix ending with non-keyword. please read #7 's test for details.

bug: non-keyword completion

.git

aaaa.bbbb.cccc.dddd

I've already implemented the solution.

My brain dump:

actu: acutual
want: want
slic: sliced actual by input
trai: trailing isk of input

feature: Add vim path variable completion support

Thanks for your work!
Can you add vim variable path completion support?
For example, here's a path variable named $VIM_PATH, which is let $VIM_PATH = fnamemodify(resolve(expand('<sfile>:p')), ':h:h') , I want to get completion infomation when I type VIM_PATH/, any idea for this? Thanks.

how to list files in the curret cwd only?

How to make ddc-source-fileonly list the files under the current folder. At the moment when I start to type, it seems to list folder starting from my home folder.

Here is my config:

call ddc#custom#patch_global('sources', ['buffer', 'file', 'vsnip', 'lsp', 'rg', 'mocword'])

call ddc#custom#patch_global('sourceOptions', {
  \ '_': {
  \   'matchers': ['matcher_fuzzy', 'matcher_length'],
  \   'converters': ['converter_truncate', 'converter_remove_overlap'],
  \   'ignoreCase': v:true,
  \   'sorters': ['sorter_rank'],
  \   'minAutoCompleteLength': 1},
  \ 'file': {
  \   'mark': 'F',
  \   'matchers': ['matcher_full_fuzzy'],
  \   'dup': v:true,
  \   'isVolatile': v:true,
  \   'forceCompletionPattern': '\S/\S*'},
  \ })

call ddc#custom#patch_filetype(
  \ ['ps1', 'dosbatch', 'autohotkey', 'registry'], {
  \ 'sourceOptions': {
  \   'file': {
  \     'forceCompletionPattern': '\S\\\S*',
  \   }},
  \ 'sourceParams': {
  \   'file': {
  \     'bufMaxItem': 0,
  \     'projFromCwdMaxItems': 0,
  \   }}})

In the screenshot, when I typed "lib", popup menu suggest "Library/", which I am not interested at all.

forceCompletionPattern should be added in the examples

Like this

  call ddc#custom#patch_global('sourceOptions', {
      \ 'file': {
      \   'mark': 'F',
      \   'isVolatile': v:true,
      \   'minAutoCompleteLength': 1000,
      \   'forceCompletionPattern': '\S/\S*'
      \ })
