inductive Lean.Lsp.CompletionIdentifier : Type

Identifier that is sent from the server to the client as part of the CompletionItem.data? field. Needed to resolve the CompletionItem when the client sends a completionItem/resolve request for that item, again containing the data? field provided by the server.

• const: Lean.Name → Lean.Lsp.CompletionIdentifier
• fvar: Lean.FVarId → Lean.Lsp.CompletionIdentifier

instance Lean.Lsp.instFromJsonCompletionIdentifier : Lean.FromJson Lean.Lsp.CompletionIdentifier

Equations

• Lean.Lsp.instFromJsonCompletionIdentifier = { fromJson? := Lean.Lsp.fromJsonCompletionIdentifier✝ }

Equations

• Lean.Lsp.instToJsonCompletionIdentifier = { toJson := Lean.Lsp.toJsonCompletionIdentifier✝ }

structure Lean.Lsp.CompletionItemDataWithIdextends Lean.Lsp.CompletionItemData : Type

CompletionItemData that also contains a CompletionIdentifier. See the documentation ofCompletionItemData and CompletionIdentifier.

def Lean.Lsp.CompletionItem.resolve (item : Lean.Lsp.CompletionItem) (id : Lean.Lsp.CompletionIdentifier) : Lean.MetaM Lean.Lsp.CompletionItem

Fills the CompletionItem.detail? field of item using the pretty-printed type identified by id.

abbrev Lean.Server.Completion.EligibleHeaderDecls : Type

Equations

• Lean.Server.Completion.EligibleHeaderDecls = Std.HashMap Lean.Name Lean.ConstantInfo

opaque Lean.Server.Completion.eligibleHeaderDeclsRef : IO.Ref (Option Lean.Server.Completion.EligibleHeaderDecls)

Cached header declarations for which allowCompletion headerEnv decl is true.

def Lean.Server.Completion.getEligibleHeaderDecls (env : Lean.Environment) : IO Lean.Server.Completion.EligibleHeaderDecls

Returns the declarations in the header for which allowCompletion env decl is true, caching them if not already cached.

structure Lean.Server.Completion.State : Type

Intermediate state while completions are being computed.

• items : Array (Lean.Lsp.CompletionItem × Float)

  All completion items and their fuzzy match scores so far.

@[reducible, inline]

abbrev Lean.Server.Completion.M (α : Type) : Type

Monad used for completion computation that allows modifying a completion State and reading CompletionParams.

Equations

• Lean.Server.Completion.M = OptionT (ReaderT Lean.Lsp.CompletionParams (StateRefT' IO.RealWorld Lean.Server.Completion.State Lean.MetaM))

partial def Lean.Server.Completion.cmpModPrivate (n₁ : Lean.Name) (n₂ : Lean.Name) : Ordering

Compares n₁ and n₂ modulo private prefixes. Similar to Name.cmp but ignores all private prefixes in both names. Necessary because the namespaces of private names do not contain private prefixes.

def Lean.Server.Completion.NameSetModPrivate : Type

NameSet where names are compared according to cmpModPrivate. Helps speed up dot completion because it allows us to look up names without first having to strip the private prefix from deep in the name, letting us reject most names without having to scan the full name first.

Equations

• Lean.Server.Completion.NameSetModPrivate = Lean.RBTree Lean.Name Lean.Server.Completion.cmpModPrivate

Fills the CompletionItem.detail? field of item using the pretty-printed type identified by id in the context found at hoverPos in infoTree.
