hcl:*max-trace-indent*

Variable

The maximum indentation used during output from trace .

hcl:*trace-indent-width*

Variable

The additional amount by which tracing output is indented upon entering a deeper level of nesting.

hcl:*trace-level*

Variable

The current depth of tracing.

cl:*trace-output*

Variable

The stream to which tracing sends its output by default.

hcl:*traced-arglist*

Variable

The variable that holds the arguments given to the traced function.

hcl:*traced-results*

Variable

The following four variables allow the output produced by tracing to be printed in a style that is controlled separately from normal printing:

hcl:*trace-print-circle*

Variable

The value to which *print-circle* is bound during output from trace .

hcl:*trace-print-length*

Variable

The value to which *print-length* is bound during output from trace .

hcl:*trace-print-level*

Variable

The value to which *print-level* is bound during output from trace .

hcl:*trace-print-pretty*

Variable

The value to which *print-pretty* is bound during output from trace .
