data PsMessage #

Constructors

PsUnknownMessage (UnknownDiagnostic (DiagnosticOpts PsMessage)) | An "unknown" message from the parser. This type constructor allows arbitrary messages to be embedded. The typical use case would be GHC plugins willing to emit custom diagnostics.
PsHeaderMessage !PsHeaderMessage | A group of parser messages emitted in `Header`. See Note [Messages from GHC.Parser.Header].
PsWarnBidirectionalFormatChars (NonEmpty (PsLoc, Char, String)) | PsWarnBidirectionalFormatChars is a warning (controlled by the -Wwarn-bidirectional-format-characters flag) that occurs when unicode bi-directional format characters are found within in a file The `PsLoc` contains the exact position in the buffer the character occurred, and the string contains a description of the character.
PsWarnTab | PsWarnTab is a warning (controlled by the -Wwarn-tabs flag) that occurs when tabulations (tabs) are found within a file. Test case(s): parsershould_failT12610 parsershould_compileT9723b parsershould_compileT9723a parsershould_compileread043 parsershould_failT16270 warningsshould_compileT9230
