tern_for_vim

tern_for_vim copied to clipboard

I have installed vim on MacOSX, and browsed through issues here + looked at docs + watched some videos on Tern for Vim, but autocomplete will not work for me at all.

Update: having some strange behavior where C-X C-O does nothing, but C-n will open autocomplete suggestion box that is non-intelligent (aka var is the first suggestion, followed by basically anything I have defined in my app). Which is also strange because C-n is mapped to toggle nerd tree (but not in insert mode, I guess that's why it works)

I have followed http://vim.wikia.com/wiki/Omni_completion reco of setting

set omnifunc=syntaxcomplete#Complete

and added recommended vimrc settings

let g:term_map_keys=1
let g:term_show_argument_hints="on_hold"

I have also tried

set omnifunc=syntaxcomplete#Complete
autocmd FileType javascript set omnifunc=javascriptcomplete#CompleteJS

I don't have any remaps, that I can tell, that would break Ctrl + x, Ctrl + C bindings (my vimrc is available). I did try remapping to C-space as some suggest but still nothing.

Am I missing something, like maybe I need to install ctags or maybe there is a conflicting setting in my vimrc? The :help tern docs show that if I run into problems with autocomplete, I can try :set noshowmode but this also has not helped.

Not sure if it helps any to see my vim info, but will post here in case:

I wonder if maybe this has something to do with the fact that I have ExuberantCtags installed (via homebrew) for used with Tagbar, and I have also installed https://github.com/ramitos/jsctags - it looks like possibly I am getting "dumb" ExuberantCtags (not very good with JavaScript)

Another completion module might well be the problem. Try disabling that and see if it helps. I am, unfortunately, not very knowledgeable about Vim internals, and have no idea how the preferred completion module is determined. Load order, maybe?

@netpoetica might be late to the pic, but I have these set and working on Yosemite + Vim/MacVim.

set omnifunc=syntaxcomplete#Complete let g:tern_map_keys=1 let g:tern_show_argument_hints="on_hold"

note the difference in g:tern_.. as opposed to g:term_... you have in your example. Also make sure you have a .tern-project file in place as well. Hope it helps...

@fungl164 oiiiii! I can't believe I had written "term". It's such a silly mistake that I don't think my brain would process that I could have possibly made it :-) good catch, and thank you! I am still not having a lot of luck understanding what this plugin is actually supposed to be doing. I would love to see a video from someone showing what it is they are expecting Vim to do exactly with tern_for_vim and autocomplete. I don't think my expectations are matching what is actually provided

@netpoetica Check these out...

you should be getting similar results as you would get from any other ide or code editor that uses ternjs in the background for js autocompletion...

Yea I don't seem to be having any luck either. Did you ever get it working or just give up? This is depressing lol...

No luck here, either.
