Overview of Language Specification

For complete information, please visit full specification.

Watson internally has a stack-based virtual machine called Watson VM. Each character of Watson files is considered as an instruction to Watson VM.

Integer

Integer (Int) is a 64-bit signed integer.

Basic instructions for Int are as follows:

  • B : pushes a zero to the stack
  • u : increments a value at the top of the stack
  • b : shifts a value at the top of the stack to the left by one bit
  • a : adds two values on the top of the stack

You can create arbitrary integers by using these instructions:

$ echo 'BBuaBubaBubbbaBubbbbaBubbbbbaBubbbbbba' | watson decode -t json
123
String

String is a byte array.

There are two instructions that manipulate String values:

  • ? : pushes an empty string
  • ! : appends a lowest byte of the top of the stack to a string at the second top of the stack

Every time an empty string is pushed, the ASCII characters used for stack manipulation are updated. The above six instructions B, u, b, a, ?, and !, are changed to S, h, a, k, $, and -, respectively. Pushing an empty string again resets to the orignal characters.

$ echo '?SShaakShaaaakShaaaaakShaaaaaak-SShkShaaaaakShaaaaaak-SShkShakShaaakShaaaaakShaaaaaak-SShkShakShaakShaaakShaaaaakShaaaaaak-' | watson decode -t json
"tako"
Object

Object is a set of key-value pairs.

There are two instructions that manipulate Object values:

  • ~ : pushes an empty Object
  • M : pops three values v, k, o in this order, set o[k] = v, and then pushes o

Note that once ? is invoked these are changed to + and g respectively.

Functions

func Marshal 

func Marshal(v interface{}) ([]byte, error)

Marshal converts an arbitrary value `v` into Watson by applying the following rules:

  • If v is any of int, int8, int16, int32, or int64, then v is converted to Int.
  • If v is any of uint, uint8, uint16, uint32, or uint64, then v is converted to Uint.
  • If v is float32 or float64, then v is converted to Float.
  • If v is bool, then v is converted to Bool.
  • If v is string, then v is converted to String.
  • If v is a struct that implements `types.Marshaler`, then v is converted to Value by calling `v.MarshalWatson()`.
  • If v is a struct that does not implement `types.Marshaler`, then v is converted to Object with its keys correspond to the fields of v.
  • If v is a slice or an array, then v is converted to Array with its elements converted by these rules.
  • If v is a map, then v is converted to Object with its elements converted by these rules.
  • If v is a pointer, then v is converted to `Value` by converting `*v` with these rules.

Note that you can configure struct fields by adding "watson" tag to fields. Tag must be like `watson:"name,flag1,flag2,...,flagN"`. If Marshal finds a field that has such tag, it uses `name` as a key of output instead of using the name of the field, or omits such field if `name` equals to "-".

Currntly these flags are available: 

omitempty      If the field is zero value, it will be omitted from the output.
inline         Inline the field. Currently the field must be a struct.
Example 
package main

import (
	"fmt"

	"github.com/genkami/watson"
)

type Person struct {
	FullName string `watson:"fullName"`
	Nickname string `watson:"nickname,omitempty"`
}

func main() {
	user := Person{
		FullName: "Motoaki Tanigo",
		Nickname: "YAGOO",
	}
	buf, err := watson.Marshal(&user)
	if err != nil {
		panic(err)
	}
	fmt.Printf("%s\n", buf)
}

Output:
Example (Marshaler) 
package main

import (
	"fmt"
	"time"

	"github.com/genkami/watson"
	"github.com/genkami/watson/pkg/types"
)

type Time time.Time

func (t Time) MarshalWatson() (*types.Value, error) {
	return types.NewObjectValue(map[string]*types.Value{
		"unix": types.NewIntValue(time.Time(t).Unix()),
	}), nil
}

func main() {
	now := Time(time.Now())
	buf, err := watson.Marshal(now)
	if err != nil {
		panic(err)
	}
	fmt.Printf("%s\n", buf)
}

Output:
Example (Omitempty) 
package main

import (
	"fmt"

	"github.com/genkami/watson"
)

type Profile struct {
	Name             string `watson:"name"`
	Age              int    `watson:"age,omitempty"`
	UnsecurePassword string `watson:"-"`
}

func main() {
	profile := Profile{
		Name:             "Calliope Mori",
		UnsecurePassword: "jaoijgeoaivj#&*RJI",
	}
	buf, err := watson.Marshal(&profile)
	if err != nil {
		panic(err)
	}
	fmt.Printf("%s\n", buf)
}

Output:

func Unmarshal 

func Unmarshal(buf []byte, v interface{}) error

Unmarshal converts Watson into an arbitrary object.

You can customize its behavior by implementing `types.Unmarshaler`.

See Marshal for details.

Example 
package main

import (
	"fmt"

	"github.com/genkami/watson"
)

type Music struct {
	Track int    `watson:"track"`
	Title string `watson:"title"`
}
