Built-in functions

Built-in functions are provided by the compiler and need no module prefix. They fall into four groups:

Page	Functions
Geometry	rect, crect, polygon, path, text
Constraints	float, eq, dimension
Hierarchy	inst, bbox
Collections	list, cons, head, tail, range_full

Functions written in Argon itself live under std::; see the standard library.

Types

Category	Types
Scalars	Float, Int, Bool, String, Any, ()
Geometry	Rect, Polygon, Path, Point
Hierarchy	Cell, Inst
Collections	[T], (A, B)

Signature notation

• Arguments before the keyword list are positional and required.
• name? is an optional keyword argument.
• T is a type parameter inferred from the arguments.
• Initial values end in i, such as x0i or widthi.
• Unless stated otherwise, coordinates and dimensions are Float.
