data PsMessage Source #

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

Fields

- !Word

  Number of other occurrences other than the first one

PsWarnTransitionalLayout !TransLayoutReason | PsWarnTransitionalLayout is a warning (controlled by the -Walternative-layout-rule-transitional flag) that occurs when pipes ('|') or 'where' are at the same depth of an implicit layout block. Example(s): f :: IO () f | True = do let x = () y = () return () | True = return () Test case(s): layout/layout006 layout/layout003 layout/layout001
PsWarnUnrecognisedPragma !String ![String] | Unrecognised pragma. First field is the actual pragma name which might be empty. Second field is the set of valid candidate pragmas.
PsWarnMisplacedPragma !FileHeaderPragmaType |
PsWarnHaddockInvalidPos | Invalid Haddock comment position
PsWarnHaddockIgnoreMulti | Multiple Haddock comment for the same entity
PsWarnStarBinder | Found binding occurrence of "*" while StarIsType is enabled
PsWarnStarIsType | Using "*" for Type without StarIsType enabled
PsWarnImportPreQualified | Pre qualified import with `WarnPrepositiveQualifiedModule` enabled
PsWarnOperatorWhitespaceExtConflict !OperatorWhitespaceSymbol |
PsWarnOperatorWhitespace !FastString !OperatorWhitespaceOccurrence |

PsWarnViewPatternSignatures !(LPat GhcPs) !(LPat GhcPs)

PsWarnViewPatternSignatures is a warning triggered by view patterns whose RHS is an unparenthesised pattern signature. It warns on code that is highly likely to break when the precedence of view patterns relative to pattern signatures is changed per GHC Proposal #281. The suggested fix is to add parentheses.

Example: f1 (isJust -> True :: Bool) = ()

Suggested fix: f1 (isJust -> (True :: Bool)) = ()
