.
(list:is_empty [LIST])
(set:is_empty [SET])
Returns true if, and only if [LIST]
or [SET]
is empty.
(list:remove [COMPUTATION*]+ [LIST])
(set:remove [COMPUTATION*]+ [SET])
Returns a copy of the collection with one instance of [COMPUTATION*]
having been removed. The variable shorthand cannot be used if the collection is a collection of strings.
As a shorthand, multiple computations can be specified. They will all be removed in order.
(list:remove_each [COMPUTATION*]+ [LIST])
(set:remove_each [COMPUTATION*]+ [SET])
Returns a copy of the collection with all instances of [COMPUTATION*]
having been removed. The variable shorthand cannot be used if the collection is a collection of strings.
As a shorthand, multiple computations can be specified. They will all be removed from the list.
(list:remove_all [removed: COLLECTION]+ [LIST])
(set:remove_all [removed: COLLECTION]+ [SET])
Returns a copy of the collection with all elements of [removed]
having been
removed.
As a shorthand, multiple [removed]
can be specified. Their elements will all
be removed.
(list:remove_at [INT] [LIST])
(set:remove_at [INT] [SET])
Returns a copy of the collection with the element at index [INT]
having been
removed.
(list:push_left [COMPUTATION*] [LIST])
(list:push_right [COMPUTATION*] [LIST])
(set:push_left [COMPUTATION*] [SET])
(set:push_right [COMPUTATION*] [SET])
Returns a list corresponding to the given [LIST]
or [SET]
to which the
[COMPUTATION*]
has been added to the right (push_right
) or the left
(push_left
).

(list:filter [LAMBDA BOOL (X)] [X LIST])
(set:filter [LAMBDA BOOL (X)] [X SET])
Returns a copy of [X LIST]
or [X SET]
in which only the elements for which
[LAMBDA BOOL (X)]
returns true
remain.
(list:indexed_filter [LAMBDA BOOL (INT X)] [X LIST])
(set:indexed_filter [LAMBDA BOOL (INT X)] [X SET])
Returns a copy of [X LIST]
or [X SET]
in which only the elements for which
[LAMBDA BOOL (INT X)]
(with INT
being the element’s index) returns true
remain.
(list:foldl [LAMBDA X (X Y)] [X COMPUTATION*] [Y LIST])
(list:foldr [LAMBDA X (X Y)] [X COMPUTATION*] [Y LIST])
(set:foldl [LAMBDA X (X Y)] [X COMPUTATION*] [Y SET])
(set:foldr [LAMBDA X (X Y)] [X COMPUTATION*] [Y SET])
Returns the result of iterating [LAMBDA X (X Y)]
over [Y COLLECTION]
, with
[X COMPUTATION*]
being the initial value. The direction of the iteration is
by ascending index order when using foldl
, and the opposite order when using
foldr
. The variable shorthand cannot be used for the initial value if the
lambda function returns a string.
(list:merge [LAMBDA O (X Y)] [X LIST|X SET] [Y LIST|Y SET])
(set:merge [LAMBDA O (X Y)] [X LIST|X SET] [Y LIST|Y SET])
Merges two collections into either a list (list:merge
) or a set
(set:merge
). This version of merging only continues as long as both
collections have elements. Thus, extra elements in either list are ignored.
(list:safe_merge [LAMBDA O (X Y)] [X LIST|X SET] [X COMPUTATION] [Y LIST|Y SET] [Y COMPUTATION])
(set:safe_merge [LAMBDA O (X Y)] [X LIST|X SET] [X COMPUTATION] [Y LIST|Y SET] [Y COMPUTATION])
Safely merges two collections into either a list (list:safe_merge
) or a set
(set:safe_merge
). This version of merging continues as long as either
collection has elements. If one of the two collections runs out of elements
before the other, it uses the provided default value ([X COMPUTATION]
for the
first list, [Y COMPUTATION]
for the second one).
(list:indexed_merge [LAMBDA O (INT X Y)] [X LIST|X SET] [Y LIST|Y SET])
(set:indexed_merge [LAMBDA O (INT X Y)] [X LIST|X SET] [Y LIST|Y SET])
Merges two collections into either a list (list:merge
) or a set
(set:merge
). This version of merging only continues as long as both
collections have elements. Thus, extra elements in either list are ignored.
The first parameter passed to the lambda function is the index of the element
in both collections.
(list:indexed_safe_merge [LAMBDA O (INT X INT Y)] [X LIST|X SET] [X COMPUTATION] [Y LIST|Y SET] [Y COMPUTATION])
(set:indexed_safe_merge [LAMBDA O (INT X INT Y)] [X LIST|X SET] [X COMPUTATION] [Y LIST|Y SET] [Y COMPUTATION])
Safely merges two collections into either a list (list:safe_merge
) or a set
(set:safe_merge
). This version of merging continues as long as either
collection has elements. If one of the two collections runs out of elements
before the other, it uses the provided default value ([X COMPUTATION]
for the
first list, [Y COMPUTATION]
for the second one). The first and third parameters
passed to the lambda function correspond to the index of the element in either
collection. It does not increase if the collection has no more elements and is
using the default value.
