How to setup both omni and keyword completion?

[gadamiak]

I can't manage to setup both omni and keyword completion. From my understanding the completion should use the DefaultCompletionType and if that returns no results it should then use ContextDefaultCompletionType.

What I want to achieve is to use Omni first and if that returns no results use standard keyword completion. However I can't get it working. My setup is:

  let g:SuperTabDefaultCompletionType = 'context'
  let g:SuperTabContextDefaultCompletionType = '<c-o>'
  let g:SuperTabContextTextOmniPrecedence = ['&omnifunc', '&completefunc']
  let g:SuperTabLongestEnhanced = 1

When editing a php file, the omni is used as expected and a list of, say, variables is proposed exactly the same as when manually invoking <c-x><c-o>. But when writing a comment keyword completion is not invoked as it does when manually using <c-x><c-n>. The same thing happens in html, ie. tags are completed by omni but text is not completed by keyword.

When I switch g:SuperTabContextDefaultCompletionType to '<c-n>' the effect is opposite. In php only keyword completion is triggered, ie. pushing TAB after $ shows keywords not variables and I need to manually use <c-x><c-o>. In html it's the same and even worse because the built-in omni closing of html tags doesn't work, ie. pushing TAB after </ triggers filename completion instead of omni.

I guess, I don't quite understand the config options. How this should be set up to work as I described?

Supertab refers to this as 'completion chaining' and you have to enable this on a per buffer basis with a call to SuperTabChain as described in the supertab help (:help supertab-completionchaining).

So in your case, you'll need to first remove these two settings from your config:

Remove these
let g:SuperTabContextDefaultCompletionType = '<c-o>'
let g:SuperTabContextTextOmniPrecedence = ['&omnifunc', '&completefunc']

Then you can either setup supertab's completion chaining globally like so:

autocmd FileType *
  \ if &omnifunc != '' |
  \   call SuperTabChain(&omnifunc, "<c-p>") |
  \ endif

Or if you want to enable it for just php files, you can use:

autocmd FileType *.php
  \ if &omnifunc != '' |
  \   call SuperTabChain(&omnifunc, "<c-p>") |
  \ endif
