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 commands 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.
