About

What is gpt-macro?

gpt-macro is a Rust procedural macro that leverages ChatGPT to generate code during the compilation process. Developers can use natural language prompts within their Rust code to instruct ChatGPT to fill in incomplete functions or generate test cases. This tool streamlines development by automating repetitive coding tasks and enabling rapid prototyping. It integrates directly into the Rust build system, parsing prompts and target code, then replacing the target with code extracted from ChatGPT's response. This allows the Rust compiler to continue with the generated code, making it a powerful assistant for Rust developers.

Best used for

Ideal for Rust developers who need to automate boilerplate code generation, quickly prototype functions, and automatically create unit tests. Especially valuable for accelerating development cycles and reducing manual coding effort by leveraging AI.

FAQs

What is the primary function of gpt-macro?

gpt-macro is a Rust procedural macro that uses ChatGPT to generate code at compile-time. It allows developers to provide natural language prompts within their Rust code, and the macro expands to include the AI-generated code, streamlining development.

How do I use gpt-macro in my Rust project?

To use gpt-macro, you need to obtain a ChatGPT API key and set it as an environment variable (OPENAI_API_KEY). Then, you can use the `auto_impl!{}` macro with a prompt string and target code, or the `#[auto_test(...)]` attribute for test generation.

What kind of code can gpt-macro generate?

gpt-macro can generate various types of Rust code based on the provided natural language prompts. Examples include implementing function logic, such as the fizzbuzz example, and generating unit tests for existing functions, as demonstrated with `#[auto_test]`.
