Any plans for function name and parameter autocomplete? What about autocomplete for code from headers that the current one is importing? Or anything like this that you have in works for when the lexer is finished.
I'm wondering if using libclang (like vim YouCompleteMe or Emacs Irony do) could not be a good (even if temporary) solution. Even more when GUI stuff will be available.
Well, I don't really like the idea of having to learn external APIs and trying to get libraries to work on multiple platforms etc. BUT if you want to get a clang-based auto complete working through the customization I would be happy to add any features that help that along.
