structure Lake.ConfigFieldInfo : Type

• name : Lean.Name

  The name of the field (possibly an alias).

• realName : Lean.Name

  The real name of the field in the configuration structure.

• canonical : Bool

  Whether name == realName and the field is not a parent projection.

• parent : Bool

  Whether the field is a parent projection.

def Lake.configField : Lean.ParserDescr

def Lake.configDecl : Lean.ParserDescr

An tailored structure command for producing Lake configuration data types. It supports additional field annotations and generates additional metadata used during serialization to/from Lean and TOML.

It is not a perfect superset of structure, but instead just the parts that are / could be reasonably needed by Lake.
