Amazing feats of the Abstract Syntax Tree
summary
Claims that PowerShell exposes its AST is public and that a transpiler can rewrite script blocks into runnable code are demonstrated with concrete tools: PipeScript transpiles to .ps1 via VS Code and GitHub Actions, a module pair (send-event / receive-event) replaces verbose event plumbing, and a repo metric shows ~100k generated lines from the project. Demos run live, PipeScript reports 48 languages supported, and a 700-line PipeScript template produces 700 lines → 3M lines generated of SVG helper code, showing the approach actually scales.
