SCALE compatible type generation for substrate runtimes. No dependencies on substrate crates required!

---

Accepts a SCALE encoded metadata file via CLI or a macro, and generates a Rust module with all types required for interacting with pallets for the given substrate runtime.

⚠️ Health warning ⚠️

This is a prototype, will likely be changed significantly or even destroyed completely. So do not depend on it for any production code (yet).

Current status

• Can generate all the runtime modules and types for node-runtime with metadata from https://github.com/paritytech/substrate/compare/aj-metadata-vnext.

Using the command: cargo run -p chameleon-cli | rustfmt --edition=2018 --emit=stdout, generates the following.
