Variable: SB-EXT:*INVOKE-DEBUGGER-HOOK*

package type

This is either NIL or a designator for a function of two arguments, to be run when the debugger is about to be entered. The function is run with INVOKE-DEBUGGER-HOOK bound to NIL to minimize recursive errors, and receives as arguments the condition that triggered debugger entry and the previous value of INVOKE-DEBUGGER-HOOK

This mechanism is an SBCL extension similar to the standard DEBUGGER-HOOK. In contrast to DEBUGGER-HOOK, it is observed by INVOKE-DEBUGGER even when called by BREAK.

Value

sb-debug::debugger-disabled-hook
