Before this, we only ever ran against system python preinstalled on travis (i.e. 2.7 and 3.2). This change makes sure that Vim is always build and run against the correct python version in the virtual env. Also adds mercurial (HEAD) Vim as a testing target. This patch took me forever to get right. At least 2 months and ~200 travis runs of trial and error - there is just too much finicky going on with the many virtual envs on travis, Vims strange build system that does not use python-config and LD_LIBRARY_PATH loading. En plus, the debugging insights one can glance from travis runs are rather limited. Detailed changes: - Uses less sudo and only outside of scripts. - Build correct version of Vim against correct version of Python. This needs some LD_LIBRARY_PATH magic to make sure that Vim finds the correct Python libraries at runtime. - Removes dirty hack that overwrote /usr/bin/vim with the correct Vim version to run. The test_all.py script now takes the Vim binary as a parameter.
UltiSnips
UltiSnips is the ultimate solution for snippets in Vim. It has tons of features and is very fast.
In this demo I am editing a python file. I first expand the #!
snippet, then
the class
snippet. The completion menu comes from
YouCompleteMe, UltiSnips also
integrates with neocomplete. I can
jump through placeholders and add text while the snippet inserts text in other
places automatically: when I add Animal
as a base class, __init__
gets
updated to call the base class constructor. When I add arguments to the
constructor, they automatically get assigned to instance variables. I then
insert my personal snippet for print
debugging. Note that I left insert mode,
inserted another snippet and went back to add an additional argument to
__init__
and the class snippet was still active and added another instance
variable.

Quick Start
This assumes you are using Vundle. Adapt
for your plugin manager of choice. Put this into your .vimrc
.
" Track the engine.
Plugin 'SirVer/ultisnips'
" Snippets are separated from the engine. Add this if you want them:
Plugin 'honza/vim-snippets'
" Trigger configuration. Do not use <tab> if you use https://github.com/Valloric/YouCompleteMe.
let g:UltiSnipsExpandTrigger="<tab>"
let g:UltiSnipsJumpForwardTrigger="<c-b>"
let g:UltiSnipsJumpBackwardTrigger="<c-z>"
" If you want :UltiSnipsEdit to split your window.
let g:UltiSnipsEditSplit="vertical"
UltiSnips comes with comprehensive documentation. As there are more options and tons of features I suggest you at least skim it.
