JSON::Repair 
This is a Ruby gem designed to repair broken JSON strings. Inspired by and based on the jsonrepair js library. It efficiently handles and corrects malformed JSON data, making it especially useful in scenarios where JSON output from LLMs might not strictly adhere to JSON standards. Whether it's missing quotes, misplaced commas, or unexpected characters, it ensures that the JSON data is valid and can be parsed correctly.
Installation
Add this gem to your application's Gemfield by executing:
$ bundle add json-repair
Alternatively, if you are not using Bundler to manage your dependencies:
$ gem install json-repair
Usage
Using JSON::Repair is straightforward. Simply call the repair method with a JSON string as an argument:
require 'json/repair'
# Example of repairing a JSON string
broken_json = '{name: Alice, "age": 25,}'
repaired_json = JSON.repair(broken_json)
puts repaired_json # Outputs: {"name": "Alice", "age": 25}
The repair method takes a string containing JSON data and returns a corrected version of this string, ensuring it is valid JSON.
