A builder for attributes that are applied to declarations of a common type and group them by the given attribute argument (an arbitrary Name, currently). Also creates a second "builtin" attribute used for bootstrapping, which saves the applied declarations in an IO.Ref instead of an environment extension.

Used to register elaborators, macros, tactics, and delaborators.

abbrev Lean.KeyedDeclsAttribute.Key : Type

structure Lean.KeyedDeclsAttribute.Def (γ : Type) : Type

KeyedDeclsAttribute definition.

Important: mkConst valueTypeName and γ must be definitionally equal.

• builtinName : Lean.Name

  Builtin attribute name, if any (e.g., `builtin_term_elab)

• name : Lean.Name

  Attribute name (e.g., `term_elab)

• descr : String

  Attribute description

• valueTypeName : Lean.Name
• evalKey : Bool → Lean.Syntax → Lean.AttrM Lean.KeyedDeclsAttribute.Key

  Convert Syntax into a Key, the default implementation expects an identifier.

• onAdded : Bool → Lean.Name → Lean.AttrM Unit

structure Lean.KeyedDeclsAttribute.OLeanEntry : Type

• key : Lean.KeyedDeclsAttribute.Key
• declName : Lean.Name

  Name of a declaration stored in the environment which has type mkConst Def.valueTypeName.

instance Lean.KeyedDeclsAttribute.instInhabitedOLeanEntry : Inhabited Lean.KeyedDeclsAttribute.OLeanEntry

Equations

• Lean.KeyedDeclsAttribute.instInhabitedOLeanEntry = { default := { key := default, declName := default } }

structure Lean.KeyedDeclsAttribute.AttributeEntry (γ : Type) extends Lean.KeyedDeclsAttribute.OLeanEntry : Type

• key : Lean.KeyedDeclsAttribute.Key
• declName : Lean.Name
• value : γ

  Recall that we cannot store γ into .olean files because it is a closure. Given OLeanEntry.declName, we convert it into a γ by using the unsafe function evalConstCheck.

Equations
