Build a throwaway Quarto document for syntactic tree rendering

Constructs the content of a minimal .qmd file that imports the appropriate Typst tree package and renders one syntactic tree. The generated Typst block differs depending on tree_notation:

Usage

.build_arborize_qmd(
  tree,
  tree_notation = c("simple", "structured"),
  typst_package,
  papersize = "a5",
  margin = "0.5cm"
)

Arguments

tree

A character string. The syntactic tree in the notation appropriate for tree_notation.

tree_notation

A character string. One of "simple" or "structured".

typst_package

A character string. The resolved Typst package import string, derived internally from tree_notation.

papersize

A character string. Typst paper size.

margin

A character string. Page margin.

Value

A character string containing the complete .qmd file content.

Details

• "simple" uses @preview/syntree and bracket notation

• "structured" uses @preview/lingotree and nested tree() calls

Separating this builder from arborize() makes the QMD content testable without requiring a Quarto installation.
