def getModule (name : Lean.Name) (s : optParam String "") : Lean.Name

Returns the very first part of a name: for Mathlib.Data.Set.Basic it returns Mathlib.

Equations

• getModule Lean.Name.anonymous s = Lean.Name.mkSimple s
• getModule (Lean.Name.num pre i) s = panic (toString "panic in `getModule`: did not expect numerical name: " ++ toString (Lean.Name.num pre i) ++ toString ".")
• getModule (Lean.Name.str pre s_1) s = getModule pre s_1
