Reduce Verbiage in Serialize Command

[rydtran]

The current serialize command can become verbose when converting a large serialized JSON string with nested subtrees into a JSON file. I propose adding an additional syntax to reduce the verbiage. Or even introduce a new command called deserialize that will convert a serialized tree into a JSON file.

Proposal:
  A new syntax added to serialize.
    or
  A new command called deserialize. I'm more inclined to this option since the name accurately describes the proposed behavior.

We will use the following JSON to demonstrate the differences;

{
  "people" : {
    "ryan" : {
      "age" : 23,
      "hobbies" : {
        "soccer" : "good",
        "running" : "bad"
      },
      "status" : "insomina"
    },
    "john" : {
      "age" : 45,
      "hobbies" : {
        "soccer" : "bad",
        "running" : "good"
      },
      "status": "sad"
    }
  }
}

Old Syntax:

spellbook serialize --output myfile.json --vars \
people/ryan/age=23 \
people/ryan/hobbies/soccer=good \
people/ryan/hobbies/running=bad \
people/ryan/status=insomania \
people/john/age=45 \
people/john/hobbies/soccer=bad \
people/john/hobbies/running=good \
people/john/status=sad\

New Syntax:

spellbook deserialize --output myfile.json \
people>\
ryan>age=23&hobbies>soccer=good&running=bad<status=insomania<\
john>age=45&hobbies>soccer=bad&running=good&status=sad\

Breaking Down the Syntax:

• ">" tells the program that the next value to read is a child node.
• "<" tells the program to return to the parent node.
• "&" tells the program that the next value to read is a sibling node.

Things to Note:

• After specifying "hobbies" and its child nodes, a "<" symbol is appended. The first instinct is to append "&," but a "<" symbol is needed to tell the program to return to the parent node of "hobbies." This will correctly place "status" as a sibling of "age" and "hobbies."
• The optional variable "--vars" is not needed since the serialized tree is one continuous string with no spaces.
