regexp-find-symbols regexp-string &key case-sensitive packages test external-only => symbols
A string.
A boolean.
A list of package designators, a single package designator, or the keyword
:all
.
A function of one argument returning a boolean result.
A generalized boolean.
The function
regexp-find-symbols
returns a list of symbols that match the regular expression in
regexp-string
.
case-sensitive
determines whether the match is case sensitive. The default value of
case-sensitive
is
nil
.
packages
specifies in which packages to search. The default value of
packages
is
:all
, meaning search in all packages.
test
, if supplied, must be a function of one argument, which returns
t
if the argument should be returned, and
nil
otherwise. The function
test
is applied to each symbol that matches
regexp-string
, and if it returns
nil
the symbol is not included in the returned value
symbols
. If
test
is
nil
all matches are returned. The default value of
test
is
nil
.
external-only
, if true, specifies that only external symbols should be checked, which makes the search much faster. The default value of
external-only
is
nil
.
The regular expression syntax used by
regexp-find-symbols
is similar to that used by Emacs, as described in the "Regular expression syntax" section of the
LispWorks Editor User Guide
.
To find all exported symbols that start with DEF:
(lw:regexp-find-symbols "^def" :external-only t)
To find all symbols that contain lower case "slider":
(regexp-find-symbols "slider" :case-sensitive t)
