A JSON5 parser that, among other features, supports round-trip preservation of comments

Project description

# json-five

JSON5 for Python

## Usage

`python >>> import json5 >>> json_text = """{ // This is a JSON5 comment "foo": "bar" /* this is a JSON5 block comment that can span lines /* "bacon": "eggs" } """ >>> json5.loads(json_text) {"foo": "bar", "bacon": "eggs"} `

## Project goals

  • support a similar interface to the json module with support for JSON5 sources

  • support round-trip preservation of comments

## Status/milestones

This project is in very early stages of development. The following are some milestones that hopefully will be able to be marked as done as development progresses.

  • [x] parse json5 to Python (ignoring comments) - [x] line comments - [x] block comments - [x] numeric literals - [x] trailing commas for arrays and objects - [x] line continuations - [x] ecma identifiers as object keys - [x] leading plus for numbers - [x] single quoted strings - [x] escape characters in strings

  • [ ] dump python to JSON (no comment support) - [x] indent style (that matches json) - [ ] style options (quotes, trailing commas, etc) - [ ] helper classes for dumping types as other literals (hexadecimal numbers, identifiers, etc) - [ ] support similar options to json (e.g. object_hook, parse_x, strict, ensure_ascii, etc) - [ ] string escapes according to quote style

  • [ ] support manipulation of json model (e.g. to add/edit comments)

  • [ ] dump json model with comments

  • [ ] preserve comments when loading json5 (round-trip support)

  • [ ] Optimize with a C/Cython version
