Simple bash script for installing your Vim plugins the vanilla way

get-plugins.sh

#!/usr/bin/env bash

# Enable extended globbing (we need it later)
shopt -s extglob

# What plugins we install
#
# Put the GitHub username<slash>repo name of each plugin you want in this array.
# e.g.
plugins=(

romainl/vim-cool
tpope/vim-surround
tpope/vim-unimpaired
wellle/targets.vim

)

# Remove any old plugins
rm -rf $HOME/.vim/pack
mkdir -p $HOME/.vim/pack/bundle/start

installplugin() {
  # This removes the GitHub username and two common Vim plugin name
  # prefix/suffixes
  #
  # We do this because I find it looks nicer and cleaner when doing a quick ls
  # on your plugin collection
  local plugin="$(echo "$1" | sed -e 's/.*[\/]//' -e 's/^vim-//' -e 's/\.vim//')"
  local pluginpath="$HOME/.vim/pack/bundle/start/$plugin"

  # * Don't clone the plugin's history (--depth=1) to make download faster
  # * All Vim plugins I (and I think most people) use are on GitHub
  git clone --depth=1 -q https://github.com/$1.git "$pluginpath"

  # Remove git-related files to prevent nested git repositories
  rm -rf "$pluginpath"/.git*

  # Remove any non-essential files that are not needed for the plugin to run
  rm -rf "$pluginpath"/README*
  rm -f "$pluginpath"/*.@(md|mdown|mkdown|markdown)
  rm -rf "$pluginpath"/test

  # Print a line announcing installation of the plugin on top of any previous
  # announcements. We do this to provide visual feedback to show the script is
  # working, but does not take up space.
  printf "\r\e[0KInstalled $plugin"
}

# The & is so that bash sets the installation as a background job, allowing for
# asynchronous installation (all plugins being installed at the same time).
for repo in ${plugins[@]}; do
  installplugin "$repo" &
done

# This makes the script wait for all the background jobs from installing all the
# plugins above before continuing
wait

# Clear away all output from the script
printf "\r\e[0K"
