Sort

sort sorts a list in place. With null or no argument, this sorts the list elements by their own values.

See also: shuffle

Arguments

Parameter Name	Default Value	Meaning
self	list	list to sort
byKey	optional	if given, sort each element by indexing with this key.

Usage Notes

With the byKey argument, each element is indexed by that argument, and the elements are sorted by the result. (This only works if the list elements are maps, or they are lists and byKey is an integer index.)

Example

Sorting numeric list in-place:

a = [5,3,4,1,2]
a.sort	        // results in a == [1, 2, 3, 4, 5]

Sorting objects / maps by some property:

// Let's consider people
Person = {}

newPerson = function(name, age)
  p = new Person
  p.name = name
  p.age = age
  return p
end function

john = newPerson("John", 30)
ursula = newPerson("Ursula", 20)
anna = newPerson("Anna", 40)

people = [john, ursula, anna]

people.sort "age"    // results in people == [ursula, john, anna]
people.sort "name"   // results in people == [anna, john, ursula]
