If X is unavailable, a terminal inspector is invoked. The TTY inspector
is a crude interface to describe which allows objects to be
traversed and maintains a history. This inspector prints information
about and object and a numbered list of the components of the object.
The command-line based interface is a normalread-eval-print loop, but an integer n
descends into the n'th component of the current object, and
symbols with these special names are interpreted as commands:
- U
- Move back to the enclosing object. As you descend into the
components of an object, a stack of all the objects previously seen is
kept. This command pops you up one level of this stack.
- Q, E
- Return the current object from inspect.
- R
- Recompute object display, and print again. Useful if the
object may have changed.
- D
- Display again without recomputing.
- H, ?
- Show help message.
