def Lean.String.charactersIn (a b : String) : Bool

Returns true if the characters of a occur in b in order (not necessarily contiguously), compared case-insensitively via Char.toLower.

This function assumes that a and b have size at most USize.size, which should be a safe assumption.

def Lean.Server.Completion.getDotCompletionTypeNames (type : Expr) : MetaM (Array Name)

Get type names for resolving id in s.id x₁ ... xₙ notation.

def Lean.Server.Completion.getDotIdCompletionTypeNames (type : Expr) : MetaM (Array Name)

Gets type names for resolving id in .id x₁ ... xₙ notation. The process mimics the dotted identifier notation elaboration procedure at Lean.Elab.App. Catches and ignores all errors, so no need to run this within try/catch.
