Jsonfomitter

Jsonfomitter is a software library designed to format JSON data for both human readability and machine processing. Presented as a language-agnostic tool, jsonfomitter aims to provide fast, deterministic output with configurable styles and robust error reporting. The project emphasizes streaming support to handle large JSON documents by processing input incrementally and producing output without requiring the entire document in memory.

Core features include configurable indentation and line breaks; compact and pretty formatting modes; a streaming formatter that can emit output as soon as tokens are available; error diagnostics with exact location of syntax problems; optional preservation of original value types and number formatting; and pluggable adapters for multiple programming languages.

Architecture typically consists of a lightweight core formatter and language bindings that expose the formatting interface to host languages. In practice, jsonfomitter implementations might target JavaScript, Python, and Rust, among others, to enable integration into web servers, data processing pipelines, and logging systems.

Usage scenarios include pretty-printing API responses for debugging, formatting log lines for readability, and reformatting existing JSON documents for consistency across a project. The project is described as open source, with permissive licenses and community contributions.
