# Integer List 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 Python'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
|
|
```
