[Pharo-dev] exact differences between two bits of JSON

July 17, 2014

      Hi - 

Is there a convenient way to get only the differences between two json strings (or JSONObjects, or Dictionaries)?

Say I have JSON objects (or dictionaries constructed from JSON strings):

A
{
    "glossary": {
        "title": "example glossary",
		"GlossDiv": {
            "title": "S",
			"GlossList": {
                "GlossEntry": {
                    "ID": "SGML",
					"SortAs": "SGML",
					"GlossTerm": "Standard Generalized Markup Language",
					"Acronym": "SGML",
					"Abbrev": "ISO 8879:1986",
					"GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook.",
						"GlossSeeAlso": ["GML", "XML"]
                    },
					"GlossSee": "markup"
                }
            }
        }
    }
}

and 

B

{
    "glossary": {
        "title": "example glossary",
		"GlossDiv": {
            "title": "XXXXXXX",
			"GlossList": {
                "GlossEntry": {
                    "ID": "SGML",
					"SortAs": "SGML",
					"GlossTerm": "Standard Generalized Markup Language",
					"Acronym": "SGML",
					"Abbrev": "XXXXXXX",
					"GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook.",
						"GlossSeeAlso": ["GML", "XML"]
                    },
					"GlossSee": "markup"
                }
            }
        }
    }
}

(assuming they aren't pretty printed and aren't in the same key-value order when created)

Is there a method in Pharo that will pull out the key-value pair with  the  "XXXXXXX" values  in piece B if I compare it with piece A?
