Organize PATH environment variable

The idea is to use an array, PATHS for example, to store the folders needed to be in PATH, and use the method join(), taken from this post, to merge correctly all paths.

#!/bin/bash

# Define PATH environment variable in a more organized way.
# ------------------------------------------------------------------------------
PATHS=(
  '/usr/local/sbin'
  '/usr/local/bin'
  '/usr/sbin'
  '/usr/bin'
  '/sbin'
  '/bin'
  '/snap/bin'
  '/opt/sublime_text'
  "$HOME/.config/composer/vendor/bin"
  "$HOME/.gem/ruby/2.5.0/bin"
  "$HOME/.cabal/bin"
  "$HOME/.local/bin"
  "$HOME/n/bin"
)

# Join array elements with delimiter
# @see https://zaiste.net/how_to_join_elements_of_an_array_in_bash/
# ------------------------------------------------------------------------------
join() {
  local IFS="$1"
  shift
  echo "$*"
}

# Make shellcheck happy! :) Export separated from definition.
PATH=$(join : "${PATHS[@]}")
export PATH
