Babushka is a humble tool for automating computing chores. For each job, a test, and the code to make that test pass. On the left is a babushka dep, and on the right, what happens when it's run. dep 'nginx running' do requires 'nginx configured' def netstat_cmd "netstat -an | grep '^tcp.*[.:]80 .*LISTEN'" end met? { shell?(netstat_cmd).tap {|r| log "#{r ? 'Some' : 'No'}thing listening." } } meet { log_shell 'Starting', 'initctl start nginx' } end $ babushka ‘nginx running’ nginx running { nginx configured { ✓ The config is valid. } ✓ nginx configured Nothing listening. meet { Starting… done. } Something listening. } ✓ nginx running Insta-install: sh -c "`curl https://babushka.me/up`"
