typewriter-engine

Shared parser, scanner, emitter, and drift-detection engine used by both typewriter-macros and typewriter-cli.

What's Inside

• Parser — converts syn::DeriveInput into typewriter IR (TypeDef)
• Scanner — discovers #[derive(TypeWriter)] items across project files
• Emitter orchestration — renders and writes output files for all supported languages
• Drift detection — compares expected generated outputs vs disk state for check --ci
• Project helpers — project root and config (typewriter.toml) discovery

Primary Consumers

• typewriter-macros (compile-time generation during cargo build)
• typewriter-cli (generate, check, watch commands)

Usage

This crate is primarily internal workspace infrastructure. Most users should use:

• typebridge for proc-macro-driven generation
• typewriter-cli for standalone CLI workflows
