How to use asyncomplete.vim as autocompletion?

[jiangtianli91]

Description

I have been trying to use asyncomplete.nvim to do the autocompletion. I have been playing with their template code, but it doesn't work. I wonder how could I make it work

function s:completor(opt, ctx)
  call mylanguage#get_async_completions({candidates, startcol -> asyncomplete#complete(a:opt['name'], a:ctx, startcol, candidates) })
endfunction

au User asyncomplete_setup call asyncomplete#register_source({
    \ 'name': 'mylanguage',
    \ 'allowlist': ['*'],
    \ 'completor': function('s:completor'),
    \ })

1. It is really not clear how this question is relevant for VimTeX.
2. So: Why are you asking at the VimTeX repo and not at asyncomplete.vim repo?
3. Why are you using this autocomplete function? It is really not among the current popular choices. I've listed several autocomplete plugins in the VimTeX docs, please read :help vimtex-complete-auto.

If you want to make asyncomplete.vim work, then of course, feel free. But I don't know that plugin at all and can't be of much help. If you do figure it out, feel free to propose a PR to update the VimTeX docs with a small section on this plugin.
