Lean.Log

class Lean.MonadLog (m : TypeType) extends Lean.MonadFileMap :
  • getFileMap : m Lean.FileMap
  • getRef : m Lean.Syntax

    Return the current reference syntax being used to provide position information.

  • getFileName : m String

    The name of the file being processed.

  • hasErrors : m Bool

    Return true if errors have been logged.

  • logMessage : Lean.Messagem Unit

    Log a new message.

The MonadLog interface for logging error messages.

Instances
    instance Lean.instMonadLog (m : TypeType) (n : TypeType) [MonadLift m n] [Lean.MonadLog m] :
    Equations

    Return the position (as String.pos) associated with the current reference syntax (i.e., the syntax object returned by getRef.)

    Equations
    Instances For

      Return the line and column numbers associated with the current reference syntax (i.e., the syntax object returned by getRef.)

      Equations
      Instances For

        If warningAsError is set to true, then warning messages are treated as errors.

        Log the message msgData at the position provided by ref with the given severity. If getRef has position information but ref does not, we use getRef. We use the fileMap to find the line and column numbers for the error message.
