Update to Vim8 on Centos 7

Upgrade vim

################################################################################
# Method 1: Install using rpm packages (credit to DarkMukke)
#

rpm -Uvh http://mirror.ghettoforge.org/distributions/gf/gf-release-latest.gf.el7.noarch.rpm
rpm --import http://mirror.ghettoforge.org/distributions/gf/RPM-GPG-KEY-gf.el7

# WARNING: removing  vim-minimal uninstalls `sudo` if you skip the second step
#          make sure to at least run `yum install sudo`
yum -y remove vim-minimal vim-common vim-enhanced
yum -y --enablerepo=gf-plus install vim-enhanced sudo


# This script will stop here if you run this gist from the command line by
# curling to the **raw** gist: `bash <(curl -s https://gist.githubuser......)`
exit


################################################################################
# Method 2: Install by building from scratch - contains a lot ot dependancies
#

# Setup essential build environment
yum -y groupinstall "Development Tools"
yum -y install ncurses-devel git-core

# Get source
git clone https://github.com/vim/vim && cd vim

# OPTIONAL: configure to provide a comprehensive vim - You can skip this step
#  and go  straight to `make` which will configure, compile and link with
#  defaults.

./configure --prefix=/usr --with-features=huge --enable-multibyte --with-python-config-dir=/usr/lib/python2.7/config --enable-pythoninterp=yes

# Build and install
make && sudo make install


################################################################################
# Final Check
#

# After installation check your setup with
vim --version

# You should see...
# VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Aug  2 2017 16:29:21)
# Included patches: 1-839

with a few changes I think this also work for configuring the build and install step (my python setup is different)

./configure --prefix=/usr --with-features=huge --enable-multibyte --with-python-config-dir=/usr/lib64/python3.6/config-3.6m-x86_64-linux-gnu/ --enable-pythoninterp=yes

Important to mention that vim --version will still return the old version (7.4 in my case) even after upgrading (I've only tried Method 2, compiling from source), which is very confusing, especially if you try to do this through a script and check the version.
In order to see the correct version, you should log out and log back in.

dnf copr enable hnakamur/vim
dnf install vim

vim --version -> 8.1.2300-1.el7
