structure Lean.Lsp.DiagnosticRelatedInformation : Type

structure Lean.Lsp.DiagnosticWith (α : Type) : Type

Represents a diagnostic, such as a compiler error or warning. Diagnostic objects are only valid in the scope of a resource.

LSP accepts a Diagnostic := DiagnosticWith String. The infoview also accepts InteractiveDiagnostic := DiagnosticWith (TaggedText MsgEmbed).

reference

• range : Lean.Lsp.Range

  The range at which the message applies.

• fullRange? : Option Lean.Lsp.Range

  Extension: preserve semantic range of errors when truncating them for display purposes.

• severity? : Option Lean.Lsp.DiagnosticSeverity
• code? : Option Lean.Lsp.DiagnosticCode

  The diagnostic's code, which might appear in the user interface.

• source? : Option String

  A human-readable string describing the source of this diagnostic, e.g. 'typescript' or 'super lint'.

• message : α

  Parametrised by the type of message data. LSP diagnostics use String, whereas in Lean's interactive diagnostics we use the type of widget-enriched text. See Lean.Widget.InteractiveDiagnostic.

• tags? : Option (Array Lean.Lsp.DiagnosticTag)

  Additional metadata about the diagnostic.

• relatedInformation? : Option (Array Lean.Lsp.DiagnosticRelatedInformation)

  An array of related diagnostic information, e.g. when symbol-names within a scope collide all definitions can be marked via this property.

• data? : Option Lean.Json

  A data entry field that is preserved between a textDocument/publishDiagnostics notification and textDocument/codeAction request.
