lsp#complete omnifunc isn't triggered

[kmARC]

Omnifunc completion works very nicely with the css completer:

let g:completor_css_omni_trigger = '([\w-]+|@[\w-]*|[\w-]+:\s*[\w-]*)$'

I would love to use the omnifunc completer from prabirshrestha/vim-lsp, however, It is not listing matches.

My configuration is similar to the css completion, I tried it with bash-language-server.

set omnifunc=lsp#complete
let g:completor_sh_omni_trigger = '(\w*)$'

The debug log shows that - supposedly - the omnifunc is called:

2020-02-23 08:45:50,912 [INFO][.../completor.vim/pythonx/completers/common/omni.py] omnifunc: b'lsp#complete'
2020-02-23 08:45:50,913 [INFO][.../completor.vim/pythonx/completers/common/omni.py] start: 9,0

If I press i_Ctrl-X_Ctrl_O, the completion popup appears, the omnifunc is working.

I understand that completor itself could be configured to use LSP directly, however, vim-lsp (with mattn/vim-lsp-settings) is a super nice and scalable solution to maintain LSP enginges easily.

I could also use the suggested prabirshrestha/asyncomplete.vim and prabirshrestha/asyncomplete-lsp.vim async engines, however completor gives a more configurable and nicer representation, and better configurability for triggers etc.

Maybe the sh shell example wasn't the best. The original reason I started fiddling with it is the json/yaml schema completion.

vim-lsp can be configured for example like below, and omnicompletion works perfectly with the selected schema (when I open a package.json file then then dictionary keys are completed from the json schema on schemastore.

let g:lsp_settings = {
    \ 'json-languageserver': {
    \    'workspace_config': {
    \       'json': {
    \          'schemas': [
    \             {
    \               'url': 'http://json.schemastore.org/package',
    \               'fileMatch': ['package.json'],
    \             },
    \           ],
    \          'format': {
    \             'enable': v:true,
    \           }
    \        },
    \     },
    \  },

With completor, this configuration is never passed - obviously - to the languages server (is there a way to do that?).

Note: for the json example it can be worked around by specifying "$shcema" as the first key, but that doesn't work with yamls, completion returned using $1 placeholders are not correctly interpreted

Looking for a way to pass configurations to LSP servers as well, any workarounds?

Update completor to the latest and the LSP workspace configuration can be set using the following settings:

let g:completor_filetype_map = {}

let g:completor_filetype_map.json = {
      \ 'ft': 'lsp',
      \ 'cmd': 'vscode-json-languageserver --stdio',
      \ 'insertText': 'label',
      \ 'config': {
      \   'json': {
      \      'format': { 'enable': v:false },
      \      'schemas': [
      \        {'fileMatch': ['package.json'], 'url': 'http://json.schemastore.org/package'},
      \      ]
      \    }
      \  }
      \ }
