Dropwizard logger for Ruby and WEBrick
Wouldn’t it be great if instead of webrick logs looking like:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
> ruby server.rb [2014-08-17 15:29:10] INFO WEBrick 1.3.1 [2014-08-17 15:29:10] INFO ruby 2.1.1 (2014-02-24) [x86_64-darwin13.0] [2014-08-17 15:29:10] INFO WEBrick::HTTPServer#start: pid=17304 port=8000 D, [2014-08-17T15:29:11.452223 #17304] DEBUG -- : hello from in the request localhost - - [17/Aug/2014:15:29:11 PDT] "GET / HTTP/1.1" 200 13 - -> / E, [2014-08-17T15:29:12.787505 #17304] ERROR -- : fail (RuntimeError) server.rb:57:in `block in <main>' /Users/xavier/.rubies/cruby-2.1.1/lib/ruby/2.1.0/webrick/httpservlet/prochandler.rb:38:in `call' /Users/xavier/.rubies/cruby-2.1.1/lib/ruby/2.1.0/webrick/httpservlet/prochandler.rb:38:in `do_GET' /Users/xavier/.rubies/cruby-2.1.1/lib/ruby/2.1.0/webrick/httpservlet/abstract.rb:106:in `service' /Users/xavier/.rubies/cruby-2.1.1/lib/ruby/2.1.0/webrick/httpserver.rb:138:in `service' /Users/xavier/.rubies/cruby-2.1.1/lib/ruby/2.1.0/webrick/httpserver.rb:94:in `run' /Users/xavier/.rubies/cruby-2.1.1/lib/ruby/2.1.0/webrick/server.rb:295:in `block in start_thread' localhost - - [17/Aug/2014:15:29:12 PDT] "GET /fail HTTP/1.1" 500 6 - -> /fail |
They looked like:

I thought so, hence:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 |
