Re: [slime-devel] reporting SLIME errors from Lisp

What's the best way to report errors in SLIME that were detected on the Lisp side, such as `no package FOO'? Right now in SLIME48 I just abort the RPC and log a message to the console about the error, but this is suboptimal, because all the user sees is `Evaluation aborted' or `Synchronous Lisp Evaluation aborted.' Perhaps :ABORT responses to RPCs could include optional error messages?

If the error is worth to fix just drop into the debugger. Otherwise catch the error, return a tagged result like `(ok <normal-value>)' or `(error <reason>)', and do whatever is appropriate on the Emacs side.

If you just want to print something you could also send a :background-message packet.
