jsonish_py 0.0.1

Wrapper around `jsonish` from BAML

jsonish_py

A Python wrapper around BAML's jsonish crate for flexible JSON-like parsing.

Overview

This library uses BAML's Rust-based jsonish parser to handle malformed or non-standard JSON strings that regular parsers would reject. It provides two main functions:

• parse_to_json - Parses JSON-like strings into standard JSON
• parse_to_model - A utility that combines parsing with Pydantic model validation

Installation

pip install jsonish_py

Usage

Basic JSON parsing

import jsonish_py

# Standard JSON works fine
result = jsonish_py.parse_to_json('{"name": "John", "age": 30}')
# Returns: '{"name": "John", "age": 30}'

# But it also handles malformed JSON
result = jsonish_py.parse_to_json('{"name": John, "age": 30,}')  # Missing quotes, trailing comma
result = jsonish_py.parse_to_json("{'name': 'John'}")  # Single quotes

Parsing to Pydantic models

from pydantic import BaseModel
import jsonish_py

class User(BaseModel):
    name: str
    age: int

# Parse directly to a Pydantic model
user = jsonish_py.parse_to_model('{"name": "Alice", "age": 25}', User)
print(user.name)  # Alice
print(user.age)   # 25
