declare_config_elab elabName TypeName declares a function elabName : Syntax → TacticM TypeName that elaborates a tactic configuration. The tactic configuration can be from Lean.Parser.Tactic.optConfig or Lean.Parser.Tactic.config, and these can also be wrapped in null nodes (for example, from (config)?).

The elaborator responds to the current recovery state.

For defining elaborators for commands, use declare_command_config_elab.
