15ecb2b178 Added the -fwarn-type-defaults compiler option (for when integer literals are given a default type) and fixed the few warnings that arose from doing so 2007-09-27 13:29:16 +00:00

c97d1d00c8 Changed the error type from String to ErrorReport throughout the code 
ErrorReport is of type (Maybe Meta, String), thereby adding an optional code position to error messages.

Die has been changed so that die and dieP are now implemented in terms of dieReport (:: ErrorReport -> m a).  This involved changing less code than changing die to be of type ErrorReport -> m a.  All that had to be changed directly was that Die instances now implement dieReport instead of die.

Any bits of code that "caught" errors has been changed so that it handles ErrorReport instead of String.  This ErrorReport is eventually, in Main, passed to dieIO, which will soon be changed to read the file in and provide the context.  Accordingly, MonadIO m has been added as a constraint to dieIO, and dieInternal has been changed to no longer use dieIO (because really we can't add the MonadIO constraint to dieInternal).

Various error messages have been changed.  Notably, all instances of fail in ParseOccam have been changed to use die or, wherever possible, dieP.  A similar thing has been done in EvalConstants and EvalLiterals.

3e342a621c Added ShowOccam and ShowRain type-classes, and changed existing code to use these new show methods in error messages 
The function showCode shows code as either occam or Rain depending on the frontend.  This is then used by a formatCode function that acts similar to 
printf, which makes it easy to format error messages that use showCode.
