What problem does it solve?

Provides a concise reference and learning resource for FSONL, a line-based serialization format that exposes type information at the line level and supports schema-driven validation.

Core Features & Use Cases

• Type-leading entries for immediate type visibility and easy parsing (examples include rm("tmp.log", force=true)).
• Schema binding via @schema to name positional arguments, apply defaults, and validate types.
• One-line-per-entry processing, enabling streaming, appends, and log-style workflows.
• JSON-compatible primitive values and support for arrays/objects, with a clear separation from JSONL by explicit typing.
• Two-stage parsing model: first parse syntax to AST, then bind to a typed object via schema; suitable for lightweight data pipelines and structured logging.
• Use cases include streaming data ingestion, configuration-like records, and lightweight data interchange where type information is valuable.

Quick Start

Create a simple FSONL line to observe how types appear and how the schema is applied during parsing.
