My own approach to JSON in Go.
See example in json_test.go for an idea.
There is a full (I hope) parser, but the initial idea was to generate JSON in some uniform way from different sources (yepp, sorta system monitor agent).
The point is to have special types for JSON entities that boil down to
JsonValue type:
JsonInt(no, Ints aren't "sorta floats")JsonFloatJsonBoolJsonString(all escapes, including \uXXXX are ok on input)JsonArrayJsonObject- no separate type for
null, anyone can be.
Any JsonValue has .Json() method to get a string representation of that
value suitable to send over, say, HTTP POST method.
The JsonArray can be .Append()ed and JsonObject has .Insert() method.
Any other JsonValue considered immutable (one can replace it with .Set()
method). The .Set() method accepts a "compatible" value or a string. The
"compatibility" means that you can use either float32 or float64 as value
for JsonFloat and so on. The strings are .Parse()d, while not .Set() into a JsonString.
The .Value() returns "unJSONed" version of that JsonValue (type cast still needed).
The .Equal() compares the two JsonValues to be equal and .IsNull() compares to zero-value.
