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

@[reducible, inline]

abbrev Lean.CodeAction.HoleCodeAction : Type

structure Lean.CodeAction.CommandCodeActionEntry : Type

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

• declName : Name

  The declaration to tag

• cmdKinds : Array Name

  The command kinds that this extension supports. If empty it is called on all command kinds.

instance Lean.CodeAction.instInhabitedCommandCodeActionEntry : Inhabited CommandCodeActionEntry

Equations

• Lean.CodeAction.instInhabitedCommandCodeActionEntry = { default := Lean.CodeAction.instInhabitedCommandCodeActionEntry.default }

Equations

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

structure Lean.CodeAction.CommandCodeActions : Type

The state of the command code actions extension.

• onAnyCmd : Array CommandCodeAction

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

• onCmd : NameMap (Array CommandCodeAction)

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

instance Lean.CodeAction.instInhabitedCommandCodeActions : Inhabited CommandCodeActions

Equations

• Lean.CodeAction.instInhabitedCommandCodeActions = { default := Lean.CodeAction.instInhabitedCommandCodeActions.default }

def Lean.CodeAction.instInhabitedCommandCodeActions.default : CommandCodeActions

Equations

• Lean.CodeAction.instInhabitedCommandCodeActions.default = { onAnyCmd := default, onCmd := default }

def Lean.CodeAction.CommandCodeActions.insert (self : CommandCodeActions) (tacticKinds : Array Name) (action : CommandCodeAction) : CommandCodeActions

Insert a command code action entry into the CommandCodeActions structure.

opaque Lean.CodeAction.builtinCmdCodeActions : IO.Ref CommandCodeActions

def Lean.CodeAction.insertBuiltin (args : Array Name) (proc : CommandCodeAction) : IO Unit

Equations

• Lean.CodeAction.insertBuiltin args proc = ST.Ref.modify Lean.CodeAction.builtinCmdCodeActions fun (self : Lean.CodeAction.CommandCodeActions) => self.insert args proc

opaque Lean.CodeAction.cmdCodeActionExt : PersistentEnvExtension CommandCodeActionEntry (CommandCodeActionEntry × CommandCodeAction) (Array CommandCodeActionEntry × CommandCodeActions)

An extension which collects all the command code actions.
