[mcclim-cvs] CVS update: mcclim/Apps/Inspector/inspector.lisp

Update of /project/mcclim/cvsroot/mcclim/Apps/Inspector In directory common-lisp.net:/tmp/cvs-serv3338 Modified Files: inspector.lisp Log Message: Fixed a bunch of little bugs. Added some comments. Package display was ugly in one place I forgot to change earlier, so I changed it. Numbers and strings had some weird display problems, which I've mostly fixed (and I can only hope that I didn't introduce minor bugs in some other part of the program). I think this is ready for the Mothering Sunday release!

Update of /project/mcclim/cvsroot/mcclim In directory common-lisp.net:/tmp/cvs-serv31004 Modified Files: dialog.lisp input-editing.lisp presentation-defs.lisp Log Message: Changed the handling of "empty input" for the purposes of returning a default value from ACCEPT. I eliminated the around method on STREAM-READ-CHAR that looked for activation/delimiter gestures and replaced it with an error handler on SIMPLE-PARSE-ERROR. The major effect of this is that (accept 'string) now return the empty string if the call to ACCEPT is not passed a default; other accept methods can return something useful for empty input too.
