data ErrorClass Source #

There are two classes of internal errors: actual bugs, and implementation limitations. The latter are already known and need not be reported.

externalError :: MonadError CompilerError m => Doc -> m a Source #

Raise an ExternalError based on a prettyprinting result.

externalErrorS :: MonadError CompilerError m => String -> m a Source #

Raise an ExternalError based on a string.

data InternalError Source #

An error that is not the users fault, but a bug (or limitation) in the compiler. Compiler passes should only ever report this error - any problems after the type checker are *our* fault, not the users. These are generally thrown as IO exceptions, and caught at the top level.

Constructors

Error ErrorClass Text 

compilerBug :: Text -> a Source #

Throw an InternalError that is a CompilerBug.

compilerBugS :: String -> a Source #

Like compilerBug, but with a String.

internalErrorS :: MonadError CompilerError m => String -> Doc -> m a Source #

Raise an InternalError based on a prettyprinting result.
