pj

This is a small, hand-written library for encoding and decoding JSON strings and objects in Python. I wrote it because I wanted a small example to demonstrate the simplest hand-written parser techniques and couldn't find any obvious results on Google.

Here is the original blog post explaining the concepts and implementation of this library.

Use

import pj

print(pj.to_string(pj.from_string('{"foo":{"bar":[1,2,3]}}')))

Tests

python3 -m unittest

Quality

The number detection is bad. There are tons of missing cases not handled. There is no line/column tracking. The primary purpose of this library is for education.
