UltiSnips and YouCompleteMe

Question

I have bundles ultisnips and youcompleteme installed on my macvim. The problem is that ultisnips doesn\'t work because tab is bound by ycm. I tried putting let g:UltiS

Answer 1

While Many answer works fine in this post, I just want to say that the problem is caused by key binding collision between YCM and UltiSnip, while YCM support UltiSnip snippets by default, it takes the default UltiSnip expand trigger <tab> as its completion select key, so UltiSnip snippets will not be expaned by <tab>. Give them different key binding will solve the problem, I personally use <c-n and <c-p> for YCM and use the default <tab> for UltiSnip. You can get more details with help youcompleteme doc in vim.

Answer 2

Try this suggestion on a page from the YouCompleteMe issue tracker. In your .vimrc:

let g:UltiSnipsExpandTrigger="<c-j>"

While this setting will make expanding a snippet share the default mapping for jumping forward within a snippet, it simulates TextMates' behavior as mentioned in the UltiSnips help tags.

Since I've mapped my Caps Lock key to Ctrl, this mapping works pretty smoothly.

Answer 3

I installed the UltiSnips plugin after the YouCompleteMe plugin so I thought they were conflicting, but in reality I had something more interfering:

set paste

Make sure to remove that from .vimrc if it's present.

Answer 4

copy the following code to your vimrc, and enjoy. This function will handle all issues between YCM and UltiSnips.

function! g:UltiSnips_Complete()
    call UltiSnips#ExpandSnippet()
    if g:ulti_expand_res == 0
        if pumvisible()
            return "\<C-n>"
        else
            call UltiSnips#JumpForwards()
            if g:ulti_jump_forwards_res == 0
               return "\<TAB>"
            endif
        endif
    endif
    return ""
endfunction

au BufEnter * exec "inoremap <silent> " . g:UltiSnipsExpandTrigger . " <C-R>=g:UltiSnips_Complete()<cr>"
let g:UltiSnipsJumpForwardTrigger="<tab>"
let g:UltiSnipsListSnippets="<c-e>"
" this mapping Enter key to <C-y> to chose the current highlight item 
" and close the selection list, same as other IDEs.
" CONFLICT with some plugins like tpope/Endwise
inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>"

Answer 5

As mentioned by others, mapping C-j to ultisnips works great.
let g:UltiSnipsExpandTrigger="<c-j>"

Now, if you go a bit further and install xcape and use
xcape -e "Shift_L=Control_R|J"

You unleash the power of using just the shift key for utlitsnips.

Answer 6

I use kj. This is what is in my .vimrc:

let g:UltisnipsExpandTrigger="kj".

It rarely happens that I run into word that has kj in it. If this is the case I would just wait a couple of seconds after typing k and that type j.
