Variable

Summary

Controls whether open frames are printed in debugger output.

Package

dbg

Initial Value

nil

Description

This variable is used by the debugger when it displays the stack frames. Open frames are made by the system and are normally not shown by the debugger. However if *print-open-frames* is set to t then the open frames are displayed. It is unlikely that you need to examine open frames: their use is connected with implementation details.

Examples

USER 52 > (setq dbg:*print-open-frames* t)

T

USER 53 > (car 2)

Error: Cannot take CAR of 2 

 1 (abort) return to top loop level 0.

Type :c followed by a number to proceed

USER 54 : 1 > :b 3

Open frame (5)

Open frame (5)

Call to CAR-FRAME  :       

Notes

*print-open-frames* is an extension to Common Lisp.
