It's named and used in the model of [GNU's seq][].
|
|
|
|
```
|
|
3 → 1, 2, 3
|
|
1 2 4 → 1, 3
|
|
-3 → -1, -2, -3
|
|
1 4 → 1, 2, 3, 4
|
|
1 -2 → 1, 0, -1, -2
|
|
```
|
|
|
|
## Example: `seq` with `range` and `after`
|
|
|
|
You can use `seq` in combination with `range` and `after`. The following will return 19 elements:
|
|
|
|
```
|
|
{{ range after 1 (seq 20)}}
|
|
{{ end }}
|
|
```
|
|
|
|
However, when ranging with an index, the following may be less confusing in that `$indexStartingAt1` and `$num` will return `1,2,3 ... 20`:
|
|
|
|
```
|
|
{{ range $index, $num := (seq 20) }}
|
|
$indexStartingAt1 := (add $index 1)
|
|
{{ end }}
|
|
```
