Installing and using schemacrawler for MacOS

A recipe for generating cool SQLite database diagrams with schemacrawler on MacOS

This was tested on MacOS 10.14.5 on 2019-07-16

schemacrawler is a free and open-source database schema discovery and comprehension tool. It can be invoked from the command-line to produce, using GraphViz, images/pdfs from a SQLite (or other database type) file. It can be used from the command-line to generate schema diagrams like these:

require 'resolv'

url = 'mail.bocistudio.com'
begin
  r = Resolv::DNS.open do |dns|
    dns.getresource(url, Resolv::DNS::Resource::IN::CNAME)
  end
  r.name.to_s # => return alias domain
rescue Resolv::ResolvError => e
  # handle error
