Range

range#

(let range (fun ((mut i) _b) (...))) Create a ranged closure in interval [a, b[

Note: Has a field asList to compute a list from the current state of the range, and another one reset.

Author: @SuperFola

Parameters#

• i: the beginning of the range
• _b: the end of the range

Example#

(let obj (range:range 1 10))
(print (obj.asList))  # [1 2 3 4 5 6 7 8 9]
(while (not (nil? (obj)))
    (print obj.i))  # print the current element
(print (obj.asList))  # [], the range has been used
(obj.reset)  # the range is ready to be used again
(print (obj.asList))  # [1 2 3 4 5 6 7 8 9]

forEach#

(let forEach (fun (_r _f) (...))) Run a function on each element of the range

Note: The range is unmodified.

Author: @SuperFola

Parameters#

• _r: the range object
• _f: the function

Example#

(let obj (range:range 1 10))
(range:forEach obj (fun (e) (print e)))

filter#

(let filter (fun (_range _fun) (...))) Create a list based on a range and a filter function

Note: The range is unmodified.

Author: @SuperFola

Parameters#

• _range: the range object
• _fun: the filter function

Example#

(import std.Math)
(let obj (range:range 1 10))
(print (range:filter obj math:even?))  # [2 4 6 8]

map#

(let map (fun (_range _fun) (...))) Create a list based on a range and a function to apply to each elements

Note: The range is unmodified.

Author: @SuperFola

Parameters#

• _range: the range object
• _fun: the function to apply

Example#

(let obj (range:range 1 10))
(print (range:map obj (fun (e) (* e e))))  # [1 4 9 16 25 36 49 64 81]

reduce#

(let reduce (fun (_range _fun) (...))) Create a reduced list based on a range and a reduction function

Note: The range is unmodified.

Author: @SuperFola

Parameters#

• _range: the range object
• _fun: the reduction function

Example#

(let obj (range:range 1 10))
(print (range:reduce obj (fun (e) (+ e e))))  # 45
