| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: &rest function-or-option-list
When called with no arguments, all the functions currently being
traced are printed, otherwise the arguments to :trace are function names (symbols) or option lists. An option list
starts with a function name, and the other elements of the list are
options for tracing that particular function. The options for one
function do not affect the tracing of any other function. The options
come in pairs, the first element of the pair being the option name
(i.e., a keyword), and the second part being the option value. Missing
options default to nil
. Here are some valid calls to
:trace:
:trace foo :trace foo (bar :break-before t) baz :trace (baz :inside foo :break-before t) :trace
Note that the following is invalid:
:trace foo :inside bar
You must enclose options in a list along with the function name and
the option value. If you enter the invalid case above, Lisp will
complain that :inside
does not have a function
definition.
The minimal abbreviation of :trace is :tr.
See top-level.htm for more information on top-level commands. See See The tracer in debugging.htm for information on the debugger and examples of tracing.
The options to :trace are listed in The tracer in debugging.htm. In brief the options and their arguments are:
:condition
expr
:break-before
val
:break-after
val
:break-all
val
:inside
func
:not-inside
func
:print-before
expr
:print-after
expr
:print-all
expr
:show-stack
n
Again, see The tracer in debugging.htm for details.
