-= Output Package
-Alessandro Sanino <a.sanino@arduino.cc>
-
-This package provides structs and helpers to be used in the rest of the project.
-
-Usually it is paired to link:../https://github.com/bcmi-labs/arduino-cli/common/formatter[Formatter Package]
-
-== Output structs
-Any Output struct must implement a set of functions, depending on the formatter.
-
-In the case of TextFormatter and JSONFormatter.
-[source, go]
-----
-String() string               // For Text Formatter.
-marshalJSON() ([]byte, error) // For JSON formatter.
-----
-
-Normally `marshalJSON()` is already implemented using JSON Go Tags if using structs.
-
-=== Example of correct output structs
-This is a correct example about how to build an output struct:
-
-[source, go]
-----
-// ExampleOutput is a struct which implements Formattable
-// JSON tags are used automatically by marshalJSON.
-type ExampleOutput struct {
-	ExampleOfField         interface{} `json:"exampleOfField"`
-	ExampleOfAnotherField  int         `json:"ExampleOfAnotherField"`
-	ExampleOfRequiredField string      `json:"ExampleOfRequiredField,required"`
-	ExampleOfOptionalField string      `json:"ExampleOfOptionalField,omitempty"`
-}
-
-// String() is used by fmt.Printf, fmt.Sprintf, fmt.Fprintf families of functions,
-// and TextFormatter.
-func (eo ExampleOutput) String() string {
-   ret := fmt.Sprintln("ExampleOfField:", eo.ExampleOfField)
-   ret += fmt.Sprintln("ExampleOfAnotherField:", eo.ExampleOfAnotherField)
-   ret += fmt.Sprintln("ExampleOfRequiredField (error if not set):", eo.ExampleOfRequiredField)
-   // Do not show optional fields.
-   if eo.ExampleOfOptionalField != "" {
-	   ret += fmt.Sprintln("ExampleOfOptionalField (may not appear if not set):", eo.ExampleOfField)
-   }
-   // Print that required variable is missing.
-   if eo.ExampleOfRequiredField == "" {
-	   ret += fmt.Sprintln("WARNING : Required field ExampleOfRequiredField is not set")
-   }
-   return ret
-}
