Techniques for Metaprogramming in Erlang
summary
Claims that generating Erlang is straightforward and practical get demonstrated with concrete code patterns and working tools: macros for compile‑time wrappers and assertions, parse transforms rewriting logger calls into optimized forms, and hand‑built syntax trees used to generate modules that are compiled and loaded (mochi_global style). Examples include Neotoma PEG/packrat‑parser (original and reworked generator), Lager and Erlydtl showing real rewrites, and Merle (OTP 18) simplifying AST construction, all showing produced code that compiles and runs.
