In a just synced SLIME running against a just synced CVS Emacs an GNU/Linux with Allegro 7.0 I seem to be having some trouble reading from *QUERY-IO*. One call works fine but two calls in a row drop me in a debugger, perhaps because there's some extra characters on the stream that are being considered as constituent chars. Here's a simple test case: CL-USER> (progn (read *query-io*) (read *query-io*)) :foo :bar ; Evaluation aborted The error in the debugger was this: Package "^@" not found. [Condition of type READER-ERROR] Restarts: 0: [ABORT] Abort handling SLIME request. 1: [ABORT] Abort entirely from this (lisp) process. Backtrace: 0: (SWANK::DEBUG-IN-EMACS #<READER-ERROR @ #x72144cd2>) 1: ((FLET SWANK:SWANK-DEBUGGER-HOOK SWANK::DEBUG-IT)) 2: (SWANK:SWANK-DEBUGGER-HOOK #<READER-ERROR @ #x72144cd2> #<Function SWANK-DEBUGGER-HOOK>) 3: (ERROR READER-ERROR :STREAM #<TWO-WAY-STREAM "" @ #x71345fd2> :FORMAT-CONTROL "~?~@[ [file position = ~d]~]" :FORMAT-ARGUMENTS ("Package ~S not found." ("") NIL)) 4: (READ #<TWO-WAY-STREAM "" @ #x71345fd2>) 5: (EVAL (PROGN (READ *QUERY-IO*) (READ *QUERY-IO*))) ... As far as I can tell the ^@ is a null (char-code #\^@) ==> 0 -Peter -- Peter Seibel peter@javamonkey.com Lisp is the red pill. -- John Fraser, comp.lang.lisp
