The function
inspect
is an interactive version of
describe
. It displays objects in a similar way to
describe
. Entering the inspector causes a new level of the top loop to be entered with a special prompt indicating that the inspector has been entered and showing the current inspector level.
In the modified top loop, if you enter a slot name, that slot is inspected and the current object is pushed onto an internal stack of previously inspected objects. The special variables
$
,
$$
, and
$$$
are bound to the top three objects on the inspector stack.
The following keywords are treated specially as comands by the inspector.
|
Recursively invoke a new inspector. m is an object to inspect. |
|
|
Change the inspection mode -- see Inspection modes. |
|
|
Undo last inspection. If you supply an optional integer argument, int , then the last int inspections are undone. |
|
You can get brief help listing these commands by entering
:?
at the inspector prompt.
The control variables
*inspect-print-level*
and
*inspect-print-length*
are similar to
*describe-print-level*
and
*describe-print-length*
(see above).
:dm
displays more slots of the current object. If the object has more than
*describe-length*
slots, then the first
*describe-length*
will be printed, followed by an ellipsis and then
(:dm or :dr for more)
If you enter the command
:dm
at the prompt it displays the next
*describe-length*
slots, and if you enter
:dr
it displays all the remaining slots. This only works on the last inspected object, so if you recursively inspect a slot and come back,
:dm
does not do anything useful. Typing
:d
lets you view the object again.
:ud
is equivalent to typing
:u
followed by
:d
.
