treeToCode :: BuilderTree -> String

Convert a BuilderTree to compilable PureScript code Now generates evalAttr syntax for true round-trip capability

type NodeId = Int

Unique identifier for nodes in the builder tree

data BuilderTree

The builder tree structure

Constructors

• BNode BuilderNode (Array BuilderTree)
• BDataJoin { elementType :: String, expanded :: Boolean, id :: NodeId, name :: String, template :: BuilderNode }

Instances

• Eq BuilderTree

type BuilderNode = { attributes :: Array AttributeBinding, elementType :: String, expanded :: Boolean, id :: NodeId, name :: Maybe String }

A node in the builder tree (editable form)

data AttributeChoice

How an attribute value is determined. This is the key abstraction that avoids runtime PureScript compilation.

Constructors

• FromField String
• ConstantNumber Number
• ConstantString String
• IndexBased
• Computed String

Instances

• Eq AttributeChoice
• Show AttributeChoice

type AttributeBinding = { attrName :: String, choice :: AttributeChoice }

An attribute binding: which attribute + how to get its value

emptyNode :: NodeId -> String -> BuilderNode

Create an empty node of a given type

defaultAttributesFor :: String -> Array AttributeBinding

Default attributes based on element type
