Credo - Analysing AST for Fun and Profit
summary
Credo analyzes Elixir source by converting code to an AST and running categorized, prioritized checks — over 40 checks grouped into readability, refactor, design, consistency and warnings — assigns numeric priorities and shows only the top three per category by default so terminals avoid 600-item dumps, offers explanations for each issue and a CLI you run with mix credo, has editor plugins and configurable lint attributes, and ships as a working teaching-focused linter.
