Getting Started - Various Issues

[cawoodm]

Just following the guide http://senecajs.org/getting-started/ and various things not working (Windows 10; NodeJS v11):

1. node math-tree.js --seneca.print.tree prints gobbledegook but no tree:

{"kind":"plugin","case":"ready","name":"transport","level":"info","actid":"9khk062to02h/2t03f921bu2o","plugin_name":"transport","pattern":"name:transport,plugin:define,role:seneca,seq:1,tag:undefined","seneca":"603h6fyvpfyg/1567440867027/10304/3.13.3/-","when":1567440867104}
{"kind":"plugin","case":"ready","name":"math","level":"info","actid":"1mqhs8vf7be5/7zpezv8kbx7h","plugin_name":"math","pattern":"name:math,plugin:define,role:seneca,seq:2,tag:undefined","seneca":"603h6fyvpfyg/1567440867027/10304/3.13.3/-","when":1567440867123}
{"kind":"notice","notice":"hello seneca 603h6fyvpfyg/1567440867027/10304/3.13.3/-","level":"info","seneca":"603h6fyvpfyg/1567440867027/10304/3.13.3/-","when":1567440867124} 

2. curl -d '{"role":"math","cmd":"sum","left":1,"right":2}' http://localhost:10101/act similarly:

{"eraro":true,"orig":null,"code":"invalid_json","seneca":true,"package":"seneca","msg":"seneca: Invalid JSON: '{role:math,cmd:sum,left:1,right:2}'.","details":{"input":"'{role:math,cmd:sum,left:1,right:2}'"},"callpoint":"at IncomingMessage.<anonymous> (W:\\JavaScript\\microservices\\senecajs-test\\node_modules\\seneca-transport\\lib\\http.js:228:35)"}

Server prints:

["json-parse","req-body","'{role:math,cmd:sum,left:1,right:2}'","Unexpected token ' in JSON at position 0"]

Probably has something to do with how Windows/DOS handles quotes as this works:

curl -d "{\"role\":\"math\",\"cmd\":\"sum\",\"left\":1,\"right\":2}" http://localhost:10101/act
{"answer":3}

Also, many examples use console.log as the callback (e.g. .act('role:math,cmd:sum,left:1,right:2', console.log)) which is very confusing since the callback has 3 parameters and the 3rd one is very verbose. I guess back in the day when the signature was (error, response) this was not an issue but today you get pages of debug info and think it didn't work:

node math-pin-service.js --seneca.log=plugin:math produces no log output at all.
