ruby - What is Camping::Server.start invoking in /bin/camping? -

i'm studying how camping web framework works right now, , don't understand camping::server.start @ line 10 in /bin/camping doing.

i expected call start method in /lib/camping/server.rb @ line 131, , put simple puts 'hello' statement @ beginning of method, expecting statement invoked when ran /bin/camping. however, never saw puts statement called, can assume it's not start method getting called.

i feel i'm missing obvious here. here link camping github page , relevant sections of code:

github: https://github.com/camping/camping

from /bin/camping:

#!/usr/bin/env ruby  $:.unshift file.dirname(__file__) + "/../lib"  require 'camping' require 'camping/server'  begin    camping::server.start rescue optionparser::parseerror => ex    puts "did error"    stderr.puts "!! #{ex.message}"    puts "** use `#{file.basename($0)} --help` more details..."    exit 1 end 

from /lib/server.rb:

def start  if options[:server] == "console"     puts "** starting console"     @reloader.reload!     r = @reloader     eval("self", toplevel_binding).meta_def(:reload!) { r.reload!; nil }     argv.clear     irb.start     exit  else     name = server.name[/\w+$/]     puts "** starting #{name} on #{options[:host]}:#{options[:port]}"     super  end end 

my puts 'hello' on camping::server.start wasn't getting called because didn't understand how static methods defined in ruby.

start being called statically, , realize start method looking @ in snippet wasn't static method, meant start method getting called. looked camping::server , realized inherited rack::server, has following method:

def self.start(options = nil)    new(options).start end 

that method getting called, not 1 on /lib/camping/server.rb. had been looking @ wrong method.
