def Lean.Elab.Term.expandOptType (ref optType : Lean.Syntax) : Lean.Syntax

Recall that

def typeSpec := leading_parser " : " >> termParser
def optType : Parser := optional typeSpec

Equations

• Lean.Elab.Term.expandOptType ref optType = if optType.isNone = true then Lean.mkHole ref else optType[0][1]

def Lean.Elab.Term.getMatchAltsNumPatterns (matchAlts : Lean.Syntax) : Nat

Helper function for expandEqnsIntoMatch

Equations

• Lean.Elab.Term.getMatchAltsNumPatterns matchAlts = matchAlts[0][0][1][0].getSepArgs.size

def Lean.Elab.Term.expandMatchAlt (stx : Lean.TSyntax `Lean.Parser.Term.matchAlt) : Lean.MacroM (Array (Lean.TSyntax `Lean.Parser.Term.matchAlt))

Expand a match alternative such as | 0 | 1 => rhs to an array containing | 0 => rhs and | 1 => rhs.
