def Lean.Parser.Term.quot : Lean.Parser.Parser

Syntax quotation for terms.

Equations

def Lean.Parser.Command.quot : Lean.Parser.Parser

Syntax quotation for (sequences of) commands. The identical syntax for term quotations takes priority, so ambiguous quotations like `($x $y) will be parsed as an application, not two commands. Use `($x:command $y:command) instead. Multiple commands will be put in a `null node, but a single command will not (so that you can directly match against a quotation in a command kind's elaborator).

def Lean.Parser.Command.inductive : Lean.Parser.Parser

In Lean, every concrete type other than the universes and every type constructor other than dependent arrows is an instance of a general family of type constructions known as inductive types. It is remarkable that it is possible to construct a substantial edifice of mathematics based on nothing more than the type universes, dependent arrow types, and inductive types; everything else follows from those. Intuitively, an inductive type is built up from a specified list of constructor. For example, List α is the list of elements of type α, and is defined as follows:

inductive List (α : Type u) where
| nil
| cons (head : α) (tail : List α)

A list of elements of type α is either the empty list, nil, or an element head : α followed by a list tail : List α. For more information about inductive types.
