This week we're joined by Herrington Darkholme, the creator of AST Grep. AST Grep is a code search tool that uses the abstract syntax tree (AST) of your code to find patterns. We talk about the genesis of AST Grep, the efficiency of AST Grep in code searching, the challenge of expressing complex patterns, the versatility of YAML for rule expression, testing and evolving rules with AST Grep, and expanding AST Grep with SDKs and VS Code integration. You should definitely check out AST Grep if you're looking for a powerful code search tool! Episode sponsored By CodeCrafters (https://codecrafters.io/devtoolsfm) 40% Discount!
