meme.alpha.emit.render — io.github.beme-lang/meme-clj 0.10.0

Wadler-Lindig document algebra and layout engine. Generic — no meme-specific knowledge. Reusable for any pretty-printing task.

Doc types form a small algebra: DocText — literal string DocLine — newline+indent (or flat-alt when flat) DocCat — concatenation DocNest — increase indent DocGroup — try flat, break if too wide DocIfBreak — conditional on flat/break mode

layout renders a Doc tree to a string at a given page width. Use ##Inf for single-line (flat) rendering.
