def Lean.Elab.Term.expandOptType (ref : Lean.Syntax) (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 Lean.Syntax.isNone optType = 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 = let alt0 := matchAlts[0][0]; let pats := Lean.Syntax.getSepArgs alt0[1][0]; Array.size pats

def Lean.Elab.Term.expandMatchAlt (stx : Lean.TSyntax (Lean.Name.mkStr4 "Lean" "Parser" "Term" "matchAlt")) : Lean.MacroM (Array (Lean.TSyntax (Lean.Name.mkStr4 "Lean" "Parser" "Term" "matchAlt")))

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