Class JSONOne

java.lang.Object

org.sfj.JSONOne

public class JSONOne
extends Object

Single class containing classes for representing JSON objects programmatically. Includes pretty print and parser. NOT like the world needs another JSON package. But... 1) it was an interesting exercise 2) perhaps someone needs something to adapt from, etc.

Very vanilla. Null, Boolean, String, Number, Array and Map objects.

Parser (well, the scanner actually) is inefficient for large objects; it expects a single String object for input. So there is that. Would be not too tough to remedy, but you'd need pushback/lookahead etc.

Should handle backslash escaping properly, ꯍ unicode, etc.

Also, in this day and age of awesome parser frameworks, it was really fun to write a parser by hand. I used: http://www.craftinginterpreters.com/ as a refresher for how to do old school scanning/parsing. I swear I have an actual book around somewhere, but I could not find it, and I did not feel like digging through Knuth this time.
