:unhide

Arguments: &optional function-name frame-type &key package package-internals

This command and :hide affect the behavior of :zoom. They allow the user to declare that certain frames should not be printed when the stack is displayed by :zoom. To :hide a frame means that :zoom will not show it, and to :unhide a frame means that :zoom will show it. The objects which can be hidden are functions named by specific symbols, all functions named by symbols in a package, and all frames of a given type.

:unhide called with no arguments causes the list of hidden objects to revert to the default set of hidden objects (which is given below). Note that if you want to see all frames in the stack, you should call :zoom with a true value for the all argument. :unhide itself is not designed to unhide all frames.

The function-name argument, if supplied, names a function that is to be unhidden.

The frame-type argument, if supplied, names the type of frames that are to be unhidden. The four valid frame types are:

  1. :binding, which are binding frames (from let, let*, prog, labels, flet, and so on);
  2. :eval, which are evaluation frames;
  3. :interpreter, which are the interpreter machinery frames;
  4. :special-form which are the special form frames.

The package keyword argument can be used to specify that all symbols of the given package should be unhidden. The value given for this argument should be a symbol naming a package.

The package-internals keyword argument can be used to specify that internal symbols of the given package should be unhidden. The value given for this argument should be a symbol naming a package.

The default set of hidden objects includes:

The minimal abbreviation for :unhide is :unh.
