Fernando’s Corner

Fernando Correa de Oliveira provides an introduction to AST Query – From ASTs to RakuAST to ASTQuery – in which he explains how Raku’s RakuAST opens up a powerful way to analyze and transform code by working directly with its Abstract Syntax Tree (AST). ASTQuery builds on that by offering a compact, expressive query language to find the nodes you care about, capture them, and even drive compile-time rewrites.

Winding down

Thanks to all for the feedback on the new https://raku.org website. The final two comments link to comprehensive chats on reddit r/programming and lobsters… some food for thought there and I will be trying to capture the wider feedback into issues / discussions for potential improvements.

Please keep staying safe and healthy, and keep up the good work! Even after week 34 of hopefully only 209.

Meanwhile, still: Слава Україні!  Героям слава!
