neocomplete autocompletion not working correctly with syntax files


This section is in my .vimrc:

" Enable omni completion
autocmd FileType css setlocal omnifunc=csscomplete#CompleteCSS
autocmd FileType html,markdown setlocal omnifunc=htmlcomplete#CompleteTags
autocmd FileType javascript setlocal omnifunc=javascriptcomplete#CompleteJS
autocmd FileType python setlocal omnifunc=pythoncomplete#Complete
autocmd FileType xml setlocal omnifunc=xmlcomplete#CompleteTags

When editing .html files, i hit < and the neocomplete CompleteTags suggestion list pops up as expected.

Afterwards, when entering < div ng- (as in angularjs directives [no space]) nothing pops up, despite of having the syntax files for angularjs installed (through the javascript-libraries-syntax.vim plugin)

However, when executing the line set ofu=syntaxcomplete#Complete or similarily set omnifunc=syntaxcomplete#Complete everything works and i see the list of directives.

  1. shouldn't neocomplete use syntax keywords out of the box?
  2. can I use multiple omnifuncs to resolve this issue? both #CompleteTags and #Complete?

Solution

    1. shouldn't neocomplete use syntax keywords out of the box?

    It does (from neocomplete documentation, neocomplete-syntax section ):

     If you want to complete the candidates from syntax files, you need to
     install the neco-syntax plugin (https://github.com/Shougo/neco-syntax).
    
    1. can I use multiple omnifuncs to resolve this issue? both #CompleteTags and #Complete?

    Of course you can (again from neocomplete documentation, g:neocomplete#sources#omni#functions section):

    g:neocomplete#sources#omni#functions
            This dictionary which appoints omni source call functions.
            The key is 'filetype'.  The value is omnifunc name String or
            List of omnifunc name String.
            If |g:neocomplete#sources#omni#functions| [&filetype] is
            undefined, omni source calls 'omnifunc'.
            If the key is "_", used for all filetypes.
    
            Default value is {}.
    

    So add the following dictionary to your .vimrc:

    let g:neocomplete#sources#omni#functions = {
      \ 'html': ['htmlcomplete#CompleteTags', 'syntaxcomplete#Complete']
      \ }
    

    Both of first or second approach should resolve the issue.
