syntree is a typst package for rendering syntax trees / parse trees (the kind linguists use).

The name and syntax are inspired by Miles Shang’s syntree. Here’s an example to get started:

#import "@preview/syntree:0.2.0": syntree

#syntree(
  nonterminal: (font: "Linux Biolinum"),
  terminal: (fill: blue),
  child-spacing: 3em, // default 1em
  layer-spacing: 2em, // default 2.3em
  "[S [NP This] [VP [V is] [^NP a wug]]]"
)

Output tree for "This is a wug"

There’s limited support for formulas inside nodes; try #syntree("[DP$zws_i$ this]") or #syntree("[C $diameter$]").

For more flexible tree-drawing, use tree:

#import "@preview/syntree:0.2.0": tree

#let bx(col) = box(fill: col, width: 1em, height: 1em)
#tree("colors",
  tree("warm", bx(red), bx(orange)),
  tree("cool", bx(blue), bx(teal)))

Output tree of colors
