list
is one of the core data types in MiniScript.
A list is mutable, ordered sequence of values. A list literal is defined by a comma-separated series of values enclosed in square brackets.
Example:
numbers = [1, 2, 3, 4, 5]
words = ["one", "two", "three", "four", "five"]
Methods
Method | Description |
---|---|
len | Returns the length of the list, i.e., the number of items it contains |
indexOf(item) | Returns the index of the first occurrence of item in the list, or null if not found
|
push item | Adds the item to the end of the list |
remove index | Removes the element at index (note: by index, not by value!) |
pop | Removes the last element of the list, and returns it |
pull | Removes the first element of the list, and returns it |
sum | Returns the sum of all numeric values in the list |
sort | Mutates the list by sorting its elements in place |
shuffle | Mutates the list by re-ordering its elements randomly |
join(separator=" ") | Returns a string with all list elements "joined" by a separator (which defaults to a space) |
insert index, value | Mutates the list by inserting value at index |
replace oldValue, newValue, maxCount | Mutates the list by replacing occurrences of oldValue with newValue at most maxCount, if specified. If maxCount is omitted it replaces all occurrences. |
indexes | Returns a list with the indexes of the elements of the list; equivalent to range(0, theList.len-1)
|
values | Returns the values of the list (in fact it returns the list itself) |
