apropos-regexp

Arguments: string &optional package external-only case-insensitive

This function is just like apropos except the first string argument (which must be a string or a symbol) is interpreted as a regular expression. For example (the exact symbols listed may be different for you):

cl-user(2): (apropos-regexp "^def.n-.*")
excl::defun-like    [function] (xp list &rest args)
excl::defun-spec
excl::defun-proto-1
defun-proto         [macro] (name varlist &rest body)
ff::defun-foreign-callable-1 [function] (name arglist body)
ff:defun-c-callable [macro] (&whole form &rest args)
ff:defun-foreign-callable [macro] (name arglist &rest body)
sys::defun-noicheck
cl-user(3): 

The first optional argument, package, is similar to the same optional argument to apropos. It can be nil or a package designator. If it is a package designator, only symbols accessible in that package are considered.

The second and third optional arguments are Allegro CL extensions to apropos, as described in Extensions to cl:make-package, cl:disassemble, cl:open, cl:apropos in implementation.htm. If external-only is specified non-nil, only external symbols are considered. If case-insensitive is specified non-nil, a case-insensitive search is done, rather than a case-sensitive search. All the optional arguments default to nil. See Extensions to cl:make-package, cl:disassemble, cl:open, cl:apropos in implementation.htm for more information on the optional arguments.

apropos-regexp binds *print-alternate-package-name* to true

When printing output, apropos-regexp binds *print-alternate-package-name* to true, so package nicknames are always used when they exist. For example, the alternate name of the foreign-functions package is "ff", and we have:

cg-user(5): *print-alternate-package-name*
nil
cg-user(6): (format t "~S~%" 'ff:defun-foreign-callable)
foreign-functions:defun-foreign-callable
nil
cg-user(7): (apropos-regexp "^def.n-.*")
[...]
ff:defun-foreign-callable [macro] (ff::name arglist &rest ff::body)
cg-user(8):
