Helper to beautify SQL statements. Works as file or pipe.

sqlpp.rb

#!/usr/bin/env ruby
require 'open3'

# # Dependencies
# `sqlformat` and `pygmentize` are Python programs :/
# make sure it's installed and available in your path.
# ```
# $ pip install --upgrade sqlparse
# $ pip install --upgrade pygment
# $ export PATH=$PATH:~/Library/Python/3.5/bin

sql = ARGF.read.strip
cmd = 'sqlformat -k upper -i lower --reindent_aligned -' + ($stdout.isatty ? '| pygmentize -g -l sql' : '')
out, _status = Open3.capture2(cmd, stdin_data: sql)
puts out
