# Integer Slice Functions

## until

The `until`

function builds a range of integers.

```
until 5
```

The above generates the list `[0, 1, 2, 3, 4]`

.

This is useful for looping with `range $i, $e := until 5`

.

## untilStep

Like `until`

, `untilStep`

generates a list of counting integers. But it allows
you to define a start, stop, and step:

```
untilStep 3 6 2
```

The above will produce `[3 5]`

by starting with 3, and adding 2 until it is equal
or greater than 6. This is similar to Pythonâ€™s `range`

function.

## seq

Works like the bash `seq`

command.

- 1 parameter (end) - will generate all counting integers between 1 and
`end`

inclusive. - 2 parameters (start, end) - will generate all counting integers between
`start`

and`end`

inclusive incrementing or decrementing by 1. - 3 parameters (start, step, end) - will generate all counting integers between
`start`

and`end`

inclusive incrementing or decrementing by`step`

.

```
seq 5 => 1 2 3 4 5
seq -3 => 1 0 -1 -2 -3
seq 0 2 => 0 1 2
seq 2 -2 => 2 1 0 -1 -2
seq 0 2 10 => 0 2 4 6 8 10
seq 0 -2 -5 => 0 -2 -4
```
