installing vim8.1 on slc7 computers

install_vim.md

Execute the commands chunk by chunk because I haven't tested this as a whole

# setup environment
cd /cvmfs/cms.cern.ch/slc7_amd64_gcc630/cms/cmssw/CMSSW_10_2_0_pre6/ ; cmsenv ; cd -

# make containment folder somewhere and get vi
mkdir vim8
cd vim8
git clone https://github.com/vim/vim

curl -O -L http://ftp.gnu.org/pub/gnu/ncurses/${version}.tar.gz
tar xvzf ${version}
cd ${version}
./configure --prefix=`pwd`
make -j10
make install
export NCURSLIB=`pwd`/lib

# back into vim folder and start configuring
cd ../vim

make -j20
make install

# done!
# your vim should be in `vim/bin/`, so fire it up
./vim/bin

# put it on your path if things go well

Had to do
pip3 install greenlet==0.4.10 --user -U
to get deoplete to "work" (https://github.com/Shougo/deoplete.nvim)

"work" = not complain/crash, but still didn't get any useful completion out of it
