1# Integer Slice Functions
2
3## until
4
5The `until` function builds a range of integers.
6
7```
8until 5
9```
10
11The above generates the list `[0, 1, 2, 3, 4]`.
12
13This is useful for looping with `range $i, $e := until 5`.
14
15## untilStep
16
17Like `until`, `untilStep` generates a list of counting integers. But it allows
18you to define a start, stop, and step:
19
20```
21untilStep 3 6 2
22```
23
24The above will produce `[3 5]` by starting with 3, and adding 2 until it is equal
25or greater than 6. This is similar to Python's `range` function.
26
27## seq
28
29Works like the bash `seq` command.
30* 1 parameter (end) - will generate all counting integers between 1 and `end` inclusive.
31* 2 parameters (start, end) - will generate all counting integers between `start` and `end` inclusive incrementing or decrementing by 1.
32* 3 parameters (start, step, end) - will generate all counting integers between `start` and `end` inclusive incrementing or decrementing by `step`.
33
34```
35seq 5 => 1 2 3 4 5
36seq -3 => 1 0 -1 -2 -3
37seq 0 2 => 0 1 2
38seq 2 -2 => 2 1 0 -1 -2
39seq 0 2 10 => 0 2 4 6 8 10
40seq 0 -2 -5 => 0 -2 -4
41```
