Render a typed tree back to R source code

Usage

ptr_render(node, preserve_placeholders = FALSE)

Arguments

node

Typed tree root (or any node) to render.

preserve_placeholders

If FALSE (default), placeholder nodes are assumed to have been replaced by literal nodes during substitution and are rendered as today (expr_text(node$expr) as a fallback). If TRUE, any surviving placeholder node is emitted as ppX(current_pick) – the round-trippable "formula with placeholders" view. The keyword and current_pick are read directly from the node; tests in this layer stub them by hand.

Value

Character scalar of R source code.
