Reference

The reference describes implemented behavior and current restrictions. Start with the language overview for the connecting ideas, or use the support index to find a contract.

• Language contract: source and modules, types, expressions, ownership, functions, generics, errors and resource scopes, and iteration define what programs mean.
• Built-in facilities and interoperability: built-in operations, I/O, concurrency, and C interfaces specify available operations, ownership transfer, allocation, and failure behavior.
• Standard library: imported std modules, currently std.math, are written in Plenty and embedded in the compiler.
• Toolchain and implementation: building programs explains commands and artifacts; architecture explains checking, native compilation, and runtime mechanisms.
• Comparisons: Plenty and Rust compares ownership and what Rust’s unsafe permits.

Learn Plenty teaches the language through executable examples. Supplementary examples cover additional operations. Design alternatives live in Proposals; future work lives in the backlog.
