abbrev Auto.solverHints : Type

solverHints includes:

• unsatCoreDerivLeafStrings an array of Strings that appear as leaves in any derivation for any fact in the unsat core
• selectorInfos which is an array of
  • The SMT selector name (String)
  • The constructor that the selector is for (Expr)
  • The index of the argument it is a selector for (Nat)
  • The type of the selector function (Expr)
• preprocessFacts : List Expr
• theoryLemmas : List Expr
• instantiations : List Expr
• computationLemmas : List Expr
• polynomialLemmas : List Expr
• rewriteFacts : List (List Expr)

Note 1: In all fields except selectorInfos, there may be loose bound variables. The loose bound variable #i corresponds to the selector indicated by selectorInfos[i]

Note 2: When the external solver is cvc5, all fields can be populated, but when the external solver is Zipperposition, only the first field (unsatCoreDerivLeafStrings) will be populated

def Auto.callNative_direct (nonempties valids : Array Embedding.Lam.REntry) (prover : Array Lemma → Array Lemma → Lean.MetaM Lean.Expr) : LamReif.ReifM Lean.Expr

Similar in functionality compared to callNative_checker, but all valid entries are supposed to be reified facts (so there should be no etoms). We invoke the prover to get the same proof as callNativeChecker, but we return a proof of ⊥ by applying proof to un-reified facts.

def Auto.buildSelectorForInhabitedType (selCtor : Lean.Expr) (argIdx : Nat) : Lean.MetaM Lean.Expr

Given the constructor selCtor of some inductive datatype and an argIdx which is less than selCtor's total number of fields, buildSelectorForInhabitedType uses the datatype's recursor to build a function that takes in the datatype and outputs a value of the same type as the argument indicated by argIdx. This function has the property that if it is passed in selCtor, it returns the argIdxth argument of selCtor, and if it is passed in a different constructor, it returns the default value of the appropriate type.
