structure Lean.Meta.GeneralizeArg : Type

• expr : Lean.Expr
• xName? : Option Lake.Name
• hName? : Option Lake.Name

The generalize tactic takes arguments of the form h : e = x

def Lean.MVarId.generalize (mvarId : Lean.MVarId) (args : Array Lean.Meta.GeneralizeArg) : Lean.MetaM (Array Lean.FVarId × Lean.MVarId)

Telescopic generalize tactic. It can simultaneously generalize many terms. It uses kabstract to occurrences of the terms that need to be generalized.

def Lean.Meta.generalize (mvarId : Lean.MVarId) (args : Array Lean.Meta.GeneralizeArg) : Lean.MetaM (Array Lean.FVarId × Lean.MVarId)

Telescopic generalize tactic. It can simultaneously generalize many terms. It uses kabstract to occurrences of the terms that need to be generalized.

def Lean.MVarId.generalizeHyp (mvarId : Lean.MVarId) (args : Array Lean.Meta.GeneralizeArg) (hyps : optParam (Array Lean.FVarId) #[]) (fvarSubst : optParam Lean.Meta.FVarSubst { map := ∅ }) : Lean.MetaM (Lean.Meta.FVarSubst × Array Lean.FVarId × Lean.MVarId)

Extension of generalize to support generalizing within specified hypotheses. The hyps array contains the list of hypotheses within which to look for occurrences of the generalizing expressions.
