opaque Lean.docStringExt : MapDeclarationExtension String

def Lean.addBuiltinDocString (declName : Name) (docString : String) : IO Unit

Adds a builtin docstring to the compiler.

Links to the Lean manual aren't validated.

Equations

• Lean.addBuiltinDocString declName docString = ST.Ref.modify Lean.builtinDocStrings✝ fun (x : Lean.NameMap String) => x.insert declName docString.removeLeadingSpaces

def Lean.addDocStringCore' {m : Type → Type} [Monad m] [MonadError m] [MonadEnv m] (declName : Name) (docString? : Option String) : m Unit

Equations

• Lean.addDocStringCore' declName (some docString) = Lean.addDocStringCore declName docString
• Lean.addDocStringCore' declName none = pure ()

def Lean.findSimpleDocString? (env : Environment) (declName : Name) (includeBuiltin : Bool := true) : IO (Option String)

Finds a docstring without performing any alias resolution or enrichment with extra metadata.

Docstrings to be shown to a user should be looked up with Lean.findDocString? instead.
