Functionality related to tactic-mode and term-mode goals with embedded CodeWithInfos.

structure Lean.Widget.InteractiveHypothesisBundle : Type

In the infoview, if multiple hypotheses h₁, h₂ have the same type α, they are rendered as h₁ h₂ : α. We call this a 'hypothesis bundle'. We use none instead of some false for booleans to save space in the json encoding.

• names : Array String

  The user-friendly name for each hypothesis. Note that these are not Names: they are pretty-printed and do not remember the macro scopes.

• fvarIds : Array Lean.FVarId

  The ids for each variable. Should have the same length as names.

• type : Lean.Widget.CodeWithInfos
• val? : Option Lean.Widget.CodeWithInfos

  The value, in the case the hypothesis is a let-binder.

• isInstance? : Option Bool

  The hypothesis is a typeclass instance.

• isType? : Option Bool

  The hypothesis is a type.

• isInserted? : Option Bool

  If true, the hypothesis was not present on the previous tactic state. Only present in tactic-mode goals.

• isRemoved? : Option Bool

  If true, the hypothesis will be removed in the next tactic state. Only present in tactic-mode goals.

structure Lean.Widget.InteractiveGoalCore : Type

The shared parts of interactive term-mode and tactic-mode goals.

• hyps : Array Lean.Widget.InteractiveHypothesisBundle

  The target type.

• ctx : Lean.Server.WithRpcRef Lean.Elab.ContextInfo

  Metavariable context that the goal is well-typed in.

structure Lean.Widget.InteractiveGoalextends Lean.Widget.InteractiveGoalCore : Type

An interactive tactic-mode goal.

• type : Lean.Widget.CodeWithInfos
• ctx : Lean.Server.WithRpcRef Lean.Elab.ContextInfo
• userName? : Option String

  The name foo in case foo, if any.

• goalPrefix : String

  The symbol to display before the target type. Usually ⊢ but conv goals use ∣ and it could be extended.

• mvarId : Lean.MVarId

  Identifies the goal (ie with the unique name of the MVar that it is a goal for.)

• isInserted? : Option Bool

  If true, the goal was not present on the previous tactic state.

• isRemoved? : Option Bool

  If true, the goal will be removed on the next tactic state.
