Understanding and Avoiding Common Pitfalls in Elixir Metaprogramming

Source: kobrakai.de

This extensive blog post by Benjamin Milde explores the intricacies and challenges of metaprogramming in Elixir. The post begins by highlighting a popular Elixir forum question regarding the use of `quote/2` and `unquote/1`, then delves deeper into the complexities of macros dealing with module bodies and functions. Milde provides practical examples and detailed explanations to illustrate these concepts, including the process of generating Elixir code from Elixir code using metaprogramming techniques. The post also touches on abstract syntax trees (AST) and how they are leveraged in metaprogramming. Milde offers insights into debugging macros, handling nested `quote/2` contexts, and using `@external_resource` to manage dependencies on external files, all while emphasizing the importance of understanding the fundamental principles of metaprogramming before diving into more advanced techniques.

Implementing RAG System for Elixir Codebases

This article is the second post in a series about using a Retrieval Augmented Generation (RAG) system for managing codebases. It focuses on adapting a previously discussed RAG system, initially designed for Ruby, to work with Elixir code. The article explores techniques like text splitting and chunking to help a language model understand Elixir code, leveraging tools like LangChain and Tree-sitter.
