def IO.throwServerError {α : Type} (err : String) : IO α

Throws an IO.userError.

Equations

• IO.throwServerError err = throw (IO.userError err)

def IO.FS.Stream.chainRight (a b : IO.FS.Stream) (flushEagerly : Bool := false) : IO.FS.Stream

Chains two streams by creating a new stream s.t. writing to it just writes to a but reading from it also duplicates the read output into b, c.f. a | tee b on Unix. NB: if a is written to but this stream is never read from, the output will not be duplicated. Use this if you only care about the data that was actually read.

def IO.FS.Stream.chainLeft (a b : IO.FS.Stream) (flushEagerly : Bool := false) : IO.FS.Stream

Like tee a | b on Unix. See chainOut.

def IO.FS.Stream.withPrefix (a : IO.FS.Stream) (pre : String) : IO.FS.Stream

Prefixes all written outputs with pre.

structure Lean.Server.DocumentMeta : Type

Meta-Data of a document.

• uri : Lean.Lsp.DocumentUri

  URI where the document is located.

• version : Nat

  Version number of the document. Incremented whenever the document is edited.

• text : Lean.FileMap

  Current text of the document. It is maintained such that it is normalized using String.crlfToLf, which preserves logical line/column numbers. (Note: we assume that edit operations never split or merge \r\n line endings.)

• dependencyBuildMode : Lean.Lsp.DependencyBuildMode

  Controls when dependencies of the document are built on textDocument/didOpen notifications.

instance Lean.Server.instInhabitedDocumentMeta : Inhabited Lean.Server.DocumentMeta

Equations

• Lean.Server.instInhabitedDocumentMeta = { default := { uri := default, version := default, text := default, dependencyBuildMode := default } }

def Lean.Server.DocumentMeta.mkInputContext (doc : Lean.Server.DocumentMeta) : Lean.Parser.InputContext

Extracts an InputContext from doc.

def Lean.Server.replaceLspRange (text : Lean.FileMap) (r : Lean.Lsp.Range) (newText : String) : Lean.FileMap

Replaces the range r (using LSP UTF-16 positions) in text (using UTF-8 positions) with newText.

Equations

• One or more equations did not get rendered due to their size.

def Lean.Server.maybeTee (fName : String) (isOut : Bool) (h : IO.FS.Stream) : IO IO.FS.Stream

Duplicates an I/O stream to a log file fName in LEAN_SERVER_LOG_DIR if that envvar is set.

def Lean.Server.applyDocumentChange (oldText : Lean.FileMap) (change : Lean.Lsp.TextDocumentContentChangeEvent) : Lean.FileMap

Returns the document contents with the change applied.

def Lean.Server.foldDocumentChanges (changes : Array Lean.Lsp.TextDocumentContentChangeEvent) (oldText : Lean.FileMap) : Lean.FileMap

Returns the document contents with all changes applied.

def Lean.Server.mkPublishDiagnosticsNotification (m : Lean.Server.DocumentMeta) (diagnostics : Array Lean.Lsp.Diagnostic) : Lean.JsonRpc.Notification Lean.Lsp.PublishDiagnosticsParams

Constructs a textDocument/publishDiagnostics notification.

Equations

• Lean.Server.mkPublishDiagnosticsNotification m diagnostics = { method := "textDocument/publishDiagnostics", param := { uri := m.uri, version? := some ↑m.version, diagnostics := diagnostics } }

def Lean.Server.mkFileProgressNotification (m : Lean.Server.DocumentMeta) (processing : Array Lean.Lsp.LeanFileProgressProcessingInfo) : Lean.JsonRpc.Notification Lean.Lsp.LeanFileProgressParams

Constructs a $/lean/fileProgress notification.

def Lean.Server.mkFileProgressAtPosNotification (m : Lean.Server.DocumentMeta) (pos : String.Pos) (kind : Lean.Lsp.LeanFileProgressKind := Lean.Lsp.LeanFileProgressKind.processing) : Lean.JsonRpc.Notification Lean.Lsp.LeanFileProgressParams

Constructs a $/lean/fileProgress notification from the given position onwards.

def Lean.Server.mkFileProgressDoneNotification (m : Lean.Server.DocumentMeta) : Lean.JsonRpc.Notification Lean.Lsp.LeanFileProgressParams

Constructs a $/lean/fileProgress notification marking processing as done.

def Lean.Server.mkApplyWorkspaceEditRequest (params : Lean.Lsp.ApplyWorkspaceEditParams) : Lean.JsonRpc.Request Lean.Lsp.ApplyWorkspaceEditParams

def String.Range.toLspRange (text : Lean.FileMap) (r : String.Range) : Lean.Lsp.Range

Converts an UTF-8-based String.range in text to an equivalent LSP UTF-16-based Lsp.Range in text.

def System.SearchPath.searchModuleNameOfUri (srcSearchPath : System.SearchPath) (uri : Lean.Lsp.DocumentUri) : IO (Option Lean.Name)

Attempts to find a module name in the roots denoted by srcSearchPath for uri. Fails if uri is not a file:// uri or if the given uri cannot be found in srcSearchPath.
