Expanding Quarto's Capabilities with Lua
summary
Shows how Lua filters actually modify the Pandoc AST to solve concrete problems, with working examples: a filter that appends a trademark symbol to every "Acme Inc" string and a header filter that inserts decorative suits, both producing the expected HTML output. Explains use of the .native AST dump, the three API layers — Lua base, Pandoc AST, Quarto Lua API — and how to package and distribute filters as extensions using quarto add from GitHub so they reuse across projects.
