Listing snippets with <C-Tab> doesn’t work

[Profpatsch]

Output of :verbose map <c-tab>:

s <C-Tab> *<Esc>:call UltiSnips_ListSnippets()<CR>
            Last set from ~/.vim/bundle/ultisnips/plugin/UltiSnips.vim

From my vimrc:

" UltiSnips
"let g:UltiSnipsSnippetsDir="~/code/vim/vim-snippets-private/"
let g:UltiSnipsExpandTrigger="<tab>"
let g:UltiSnipsJumpForwardTrigger="<tab>"
let g:UltiSnipsJumpBackwardTrigger="<s-tab>"
let g:UltiSnipsListSnippets="<c-tab>"
" }}}

I am in GVim, so this can’t be a terminal issue. Looks like the function called does nothing.
I tried mapping it to stuff like <leader>xx, but this only deletes two chars (when the following key after hitting leader can’t find a corresponding mapping, it falls back to the normal command without the leader).

Using the latest github version of SirVer/UltiSnips.

You are interested in imap <c-tab>, as you want to use it in insert mode.

[Profpatsch (profpatsch)]

Oh, now I see what the 's' in the beginning is for.
But why does Ultisnips map this to select mode by default? oO

[SirVer (sirver)]

I cannot remember - I believe there was a reason.

However, this is not your problem currently, right? How about the imap?

`imap and inoremap <C-Tab> *<ESC>:call …` don’t work, they are normal
tabs.
`nnoremap <C-Tab> :call …` does work (from normal mode, of course).

I don’t know if this is related, I get the following error trying to
expand bboxes (a similar one with boxes, none with lorem)

Following is the full stack trace:

I guess that’s a whole different bug, though.

AttributeError: 'dict' object has no attribute 'has_key'

that is really odd - this is a buildin method in python. What does :py import sys; print(sys.version)

give you? What OS are you on?
What does :imap <c-tab> print?

I’m on Archlinux (python is linked to python3 and python2 to python2).
Python in vim: 2.7.3, GCC 4.7.2.

Well, there you have it. Supertab eats your settings. Check if after/plugin/ultisnips.vim is properly sourced in your installation - I bet it isn't.

About the python problem: dict.has_key is indeed no longer in python 3. A patch that fixes this in a compatible manner would be appreciated.

[SirVer (sirver)]

setting to invalid, because UltiSnips is not to blame here.

[Sawyer (evolye)]

Hi,
this can be confirmed Vim 7.4.113 with Python 3.3.
Install the latest UltiSnip from github.

:py3 import sys; print(sys.version)
3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AMD64)]

inside vimrc:
let g:UltiSnipsUsePythonVersion=3

and use <C-Tab>
and select any option, give the errors.

[SirVer (sirver)]

has_key is no longer available in python3 but was used in all.snippets - huge oversight and sorry for that. A fix has been pushed to github right now.
