Can't autocomplete css-next `vars` and `mixins`

[weichensw]

.class {
  background-color: var(--custom-color);
  @apply(--custom-mixin);
}

The default provider is at least collecting the part after --. However css provider disabled default provider.

atom/autocomplete-plus#740

Given that atom/language-css#99 was recently merged and is in the pipeline for Atom 1.15, what is the status of this issue? It would be great if custom variable auto-completion could accompany the added support for that syntax in language-css.

It may be feasible now, but someone will probably have to create a PR for it.

I don't mind having a go, after I understand whether or not #57 is a complete fix as was indicated.

I don't believe #57 actually fixes this. All it does is allow the default provider to also provide suggestions, which I think is undesirable since that introduces the possibility of nonsensical suggestions (such as display: background-image instead of display: block).
