Initial setup for code action attributes

• Attribute @[hole_code_action] collects code actions which will be called on each occurrence of a hole (_, ?_ or sorry).

• Attribute @[tactic_code_action] collects code actions which will be called on each occurrence of a tactic.

• Attribute @[command_code_action] collects code actions which will be called on each occurrence of a command.

structure Lean.CodeAction.CommandCodeActionEntry : Type

An entry in the command code actions extension, containing the attribute arguments.

• declName : Lake.Name

Equations

• Lean.CodeAction.instInhabitedCommandCodeActionEntry = { default := { declName := default, cmdKinds := default } }

structure Lean.CodeAction.CommandCodeActions : Type

The state of the command code actions extension.

• onAnyCmd : Array Lean.CodeAction.CommandCodeAction

  The list of command code actions to apply on any command.

• onCmd : Lake.NameMap (Array Lean.CodeAction.CommandCodeAction)

  The list of command code actions to apply when a particular command kind is highlighted.

instance Lean.CodeAction.instInhabitedCommandCodeActions : Inhabited Lean.CodeAction.CommandCodeActions

Equations
