Producing Diagnostic values
diagFromErrMsgs :: Text -> DynFlags -> Bag ErrMsg -> [FileDiagnostic] Source #
diagFromErrMsg :: Text -> DynFlags -> ErrMsg -> [FileDiagnostic] Source #
Produce a GHC-style error from a source span and a message.
diagFromString :: Text -> DiagnosticSeverity -> SrcSpan -> String -> [FileDiagnostic] Source #
Produce a GHC-style error from a source span and a message.
diagFromStrings :: Text -> DiagnosticSeverity -> [(SrcSpan, String)] -> [FileDiagnostic] Source #
Produce a bag of GHC-style errors (ErrorMessages) from the given
(optional) locations and message strings.
diagFromGhcException :: Text -> DynFlags -> GhcException -> [FileDiagnostic] Source #
catchSrcErrors :: DynFlags -> Text -> IO a -> IO (Either [FileDiagnostic] a) Source #
Catch the errors thrown by GHC (SourceErrors and compiler-internal exceptions like Panic or InstallationError), and turn them into diagnostics
utilities working with spans
srcSpanToFilename :: SrcSpan -> Maybe FilePath Source #
Extract a file name from a GHC SrcSpan (use message for unhelpful ones) FIXME This may not be an _absolute_ file name, needs fixing.
Arguments
| :: FastString | file path of span |
| -> RealSrcSpan |
creates a span with zero length in the filename of the argument passed
utilities working with severities
toDSeverity :: Severity -> Maybe DiagnosticSeverity Source #
Convert a GHC severity to a DAML compiler Severity. Severities below Warning level are dropped (returning Nothing).
