Batteries.Tactic.Alias

The alias command #

The alias command is used to create synonyms. The plain command can create a synonym of any declaration. There is also a version to create synonyms for the forward and reverse implications of an iff theorem.

An alias can be in one of three forms

Instances For

    The name underlying an alias target

    Equations
      Instances For

        The docstring for an alias.

                    Updates the deprecated declaration to point to target if no target is provided.

                        The command alias name := target creates a synonym of target with the given name.

                        The command alias ⟨fwd, rev⟩ := target creates synonyms for the forward and reverse directions of an iff theorem. Use _ if only one direction is required.

                        These commands accept all modifiers and attributes that def and theorem do.

                            Given a possibly forall-quantified iff expression prf, produce a value for one of the implication directions (determined by mp).
