Variable

Summary

The amount of extra indentation in the trace output for each level of nesting.

Package

hcl

Initial value

2

Description

*trace-indent-width* is the extra amount by which the traced output for function calls is indented upon entering a deeper level of nesting (that is, a traced call from a function that is itself traced). If it is 0 then no indentation occurs.

Example

CL-USER 1 > (setq *trace-indent-width* 4

                  *max-trace-indent* 50)

50

CL-USER 2 > (defun quad (a b c) (- (* b b) (* 4 a c)))

QUAD

CL-USER 3 > (trace quad *)

(QUAD *)

CL-USER 4 > (quad 4 3 14)

0 QUAD > ...

  >> A : 4

  >> B : 3

  >> C : 14

    1 * > ...

      >> SYSTEM::ARGS : (3 3)

    1 * < ...

      << VALUE-0 : 9

    1 * > ...

      >> SYSTEM::ARGS : (4 4 14)

    1 * < ...

      << VALUE-0 : 224

0 QUAD < ...

  << VALUE-0 : -215

-215

Notes

*trace-indent-width* is an extension to Common Lisp.
