| Fix the following issue: | |
| ## Feature request: iterate over a numeric range from a template | |
| I'd like to be able to loop over a numeric range directly inside a jet template. Typical use cases are rendering pagination links, repeating a UI element N times, or emitting a numbered list. | |
| Right now I don't see a way to do this from the template side alone. What I end up doing is building a throwaway slice in Go just so the template has something to `range` over: | |
| ```go | |
| // in the handler | |
| nums := make([]int, 10) | |
| for i := range nums { | |
| nums[i] = i | |
| } | |
| vars.Set("nums", nums) | |
| ``` | |
| ``` | |
| {{ range i := nums }} | |
| <a href="?page={{ i }}">{{ i }}</a> | |
| {{ end }} | |
| ``` | |
| This feels backwards — the template is the side that knows it wants to render "page 1 through page N", but it can't express that without Go-side glue. Every place that needs a numeric loop ends up repeating the same boilerplate, and it leaks template concerns into handler code. | |
| Other template engines provide something for this out of the box (Python's `range`, Twig's `..` operator, etc.). Could jet have an equivalent builtin so a template can produce a numeric sequence on its own, without the caller having to prepare a slice for it? I'd expect something like `ints(from, to)` usable directly in a `range`. |
