list-all-packages
Returns a list of all the packages that exist in Genera.
Function
zl:listarray array &optional limit Function
zl:listarray creates and returns a list whose elements are those of array.
array can be any type of array or a symbol whose function cell contains an
array.
If limit is present, it should be an integer, and only the first limit (if there
are more than that many) elements of array are used, and so the maximum
length of the returned list is limit.
If array is multidimensional, the elements are accessed in row-major order:
the last SUbscript varies the most quickly.
list-array-Ieader array &optionallimit Function
list-array-Ieader creates and returns a list whose elements are those of
array's leader. array can be any type of array or a symbol whose function
cell contains an array.
If limit is present, it should be an integer, and only the first limit (if there
are more than that many) elements of array's leader are used, and so the
maximum length of the returned list is limit. If array has no leader, nil is
returned.
zl:listify n Function
Manufactures a list of n of the arguments of a lexpr. With a positive argument
n, it returns a list of the first n arguments of the lexpr. With a
negative argument n, it returns a list of the last (abs n) arguments of the
lexpr. Basically, it works as if defined as follows:
(defun listify (n)
(cond «minusp n)
(l;stify1 (arg nil) (+ (arg nil) n 1»)
(t
(listify1 n 1» »
(de fun listify1 (n m) ; auxiliary function.
(do «; n (1- i»
(result nil (cons (arg i) result»)
«< i m) result) »
zl:listify exists only for compatibility with Maclisp lexprs. To write functions
that can accept variable numbers of arguments, use the &optional
and &rest keywords. See the section "Evaluating a Function Form" in
Symbolics Common Lisp: Language Concepts.
