#478: Command-line option to terminate process on unhandled errors -------------------------------+------------------------- Reporter: Mark Evenson | Type: enhancement Status: new | Priority: minor Milestone: 1.8.1 | Component: other Version: 1.8.1-dev | Keywords: Parent Tickets: | -------------------------------+------------------------- In <https://mailman.common-lisp.net/pipermail/armedbear- devel/2020-November/004187.html> Robert Munyer requests: {{{ Many Lisp implementations (including CCL, CLISP and SBCL) have a command-line option that causes unhandled errors to terminate the Lisp process instead of invoking the debugger. This option is useful for programs that don't have irreplaceable valuable state in the heap, and that have users whose reaction upon seeing a debug REPL would be "How do I get out of this!?". Also, a few days ago someone on IRC mentioned having the problem that "if there is an error in the expression" the server thread "gets locked in the ABCL repl". I think his or her use-case might also benefit from a debugger-disabling switch. }}} -- Ticket URL: <https://abcl.org/trac/ticket/478> armedbear <https://abcl.org> armedbear

(3.2.2.2) The file below has 4 output lines that start with "*** Expanding macro". None of those lines should be printed when the compiled file is loaded. ------- begin test-min-compilation.lisp ------- (macrolet ((m1 () (format t "~&*** Expanding macro 1.~%") '(format t "~&Output of macro 1.~%"))) (m1)) (defconstant +dc+ (macrolet ((m2 () (format t "~&*** Expanding macro 2 inside DEFCONSTANT.~%") '(format t "~&Output of macro 2.~%"))) (m2))) (defparameter *dp* (macrolet ((m3 () (format t "~&*** Expanding macro 3 inside DEFPARAMETER.~%") '(format t "~&Output of macro 3.~%"))) (m3))) (defvar *dv* (macrolet ((m4 () (format t "~&*** Expanding macro 4 inside DEFVAR.~%") '(format t "~&Output of macro 4.~%"))) (m4))) ------- end test-min-compilation.lisp ------- CCL, CLISP, ECL and SBCL print none of the 4, ABCL prints 3 of the 4.
