def Lean.Elab.PartialContextInfo.mergeIntoOuter? (inner : Lean.Elab.PartialContextInfo) (outer? : Option Lean.Elab.ContextInfo) : Option Lean.Elab.ContextInfo

Merges the inner partial context into the outer context s.t. fields of the inner context overwrite fields of the outer context. Panics if the invariant described in the documentation for PartialContextInfo is violated.

When traversing an InfoTree, this function should be used to combine the context of outer nodes with the partial context of their subtrees. This ensures that the traversal has the context from the inner node to the root node of the InfoTree available, with partial contexts of inner nodes taking priority over contexts of outer nodes.

def Lean.Elab.Info.updateContext? : Option Lean.Elab.ContextInfo → Lean.Elab.Info → Option Lean.Elab.ContextInfo

Helper function for propagating the tactic metavariable context to its children nodes. We need this function because we preserve TacticInfo nodes during backtracking and their children. Moreover, we backtrack the metavariable context to undo metavariable assignments. TacticInfo nodes save the metavariable context before/after the tactic application, and can be pretty printed without any extra information. This is not the case for TermInfo nodes. Without this function, the formatting method would often fail when processing TermInfo nodes that are children of TacticInfo nodes that have been preserved during backtracking. Saving the metavariable context at TermInfo nodes is also not a good option because at TermInfo creation time, the metavariable context often miss information, e.g., a TC problem has not been resolved, a postponed subterm has not been elaborated, etc.

This does the same job as resolveGlobalConstNoOverload; resolving an identifier syntax to a unique fully resolved name or throwing if there are ambiguities. But also adds this resolved name to the infotree. This means that when you hover over a name in the sourcefile you will see the fully resolved name in the hover info.

Use this to descend a node on the infotree that is being built.

It saves the current list of trees t₀ and resets it and then runs x >>= mkInfo, producing either an i : Info or a hole id. Running x >>= mkInfo will modify the trees state and produce a new list of trees t₁. In the i : Info case, t₁ become the children of a node node i t₁ that is appended to t₀.
