Life saver and relatively straightforward, missing the detail on the encoding/json, which has been mentioned previously but otherwise worked fine for me.

You said that @ 5:00 that config was nil but it is not. Variables in golang are defaulted to their zero values when not defined.

Another tip would be instead of using the filename as a parameter, try to pass an interface. With this approach this get easier to unittest. =]

Hi. What are your font and color scheme please ? Thanks.

Why do I have to put the same value that I have set in my struct above the struct. -> i.e: Host string `json:"host"`

[LuisFernandoGaido]

line 19, you say config return is nil, but in reality is a zero value of config type.

Actually you are forgotten to add an import called "encoding/json" before using it! The rest was great!
