Autocomplete with tab and enter to select inserts new line

[shwoodard]

STR: type fragment of matched word and press tab and then press enter on selected option

Actual: the autocomplete selects the option and inserts a new line
Expected: the autocomplete selects the option and does not insert a new line

I've discovered that esc works. Should we close this and just call this the new behavior?

[dechimp]

I agree. I would say just about anybody would expect this behavior.

I believe this is the default behavior of Vim's built-in autocomplete, however. There are some resources that discuss this issue:
http://vim.wikia.com/wiki/Make_Vim_completion_popup_menu_work_just_like_in_an_IDE
https://unix.stackexchange.com/questions/162528/select-an-item-in-vim-autocomplete-list-without-inserting-line-break

I'm going to try adding this Vimtip to my rc and see how that goes.

inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>"

I just learned that the above command seems to interfere with other things, like auto-insertion helpers for Ruby, as pointed out by chrisnicola:

I second this issue. This is not how I expect it to work. There should not be an auto-newline added. The tip provided by dechimp seems to work great for me, so far..
I now have in my vimrc:

"ENABLES AUTOCOMPLETE
Plugin 'ervandew/supertab'
inoremap
inoremap pumvisible() ? "" : "u"
