7 Meta and Macros Reference🔗ℹ

Simple pattern-based expression macros can be written using macro without importing any additional libraries besides rhombus, but implementing others forms of macros requires using the rhombus/meta module (usually with no prefix).

The rhombus/meta module provides bindings like defn.macro, expr.macro, and bind.macro. It it also re-exports most of rhombus as meta for use in compile-time expressions, but it omits bindings from rhombus that bridge to meta contexts: meta, macro, binding, etc. Explicitly import rhombus as meta to access the omitted bindings.

The rhombus/and_meta module provides all of the bindings from both rhombus and rhombus/meta. It’s intended for use as a language—an alternative to starting with rhombus and importing rhombus/meta.
