The messages aren't in a structured format currently; we just use Text.PrettyPrint.HughesPJ (in fact an internal version thereof). However we do paramterise the pretty printer by various things; e.g. whether to qualify identifiers when printing them out, so paramterising by some style options wouldn't be hard. It wouldn't be quite as general as having a type of messages that contained bits of HsSyn, though, but that would require more major refactoring. Cheers, Simon Al Falloon wrote:
If the output messages were in some sort of structured format then a simple post processor could convert them into whatever style is requested.
A post-processor that generates the current messages could be tacked-on to the end of the current compile tool-chain for backward compatibility.
This would open the door for tools that colorize the output or provide a mechanism for enhanced IDE integration.

A reasonable point. It's one of those matters of taste -- there will be people who hate double-quotes too. Yet another flag?
Really we should use colours etc. Any volunteers?
