opaque Lean.Elab.mkMacroAttribute (ref : Name) : IO (KeyedDeclsAttribute Macro)

opaque Lean.Elab.macroAttribute : KeyedDeclsAttribute Macro

Registers a macro expander for a given syntax node kind.

A macro expander should have type Lean.Macro (which is Lean.Syntax → Lean.MacroM Lean.Syntax), i.e. should take syntax of the given syntax node kind as a parameter and produce different syntax in the same syntax category.

The macro_rules and macro commands should usually be preferred over using this attribute directly.

def Lean.Elab.expandMacroImpl? (env : Environment) : Syntax → MacroM (Option (Name × Except Macro.Exception Syntax))

Try to expand macro at syntax tree root and return macro declaration name and new syntax if successful. Return none if all macros threw Macro.Exception.unsupportedSyntax.
