Explanations

Explanations help you understand why handl works the way it does. They are background reading, not step-by-step instructions.

The language

• What is handl? — the language's purpose and philosophy.
• Language overview — values, expressions, functions, and modules.
• Runtime — how handl expressions are executed.

The platform

• Platform architecture — the crate layers and how they compose.
• The composable host — why the platform is built around a single plugin model.
• Plugins, rules, and operations — how Plugin, RuleAcceptor, Operation, and Behavior fit together.
• Kits and manifests — how kits curate plugins and defaults.
• Options and configuration — how options are defined, resolved, and used.
• Security and trust — threat model and recommended practices.

The standard library

• Why strings, chars, and Unicode live in three layers — why the string stack is split into algorithms (handl), Unicode tables (Rust floor), and ICU (future swappable backend).
