The counter is global for both monolingual and multilingual sites, and its initial value for each build is 1.
|
|
|
|
```go-html-template {file="layouts/page.html"}
|
|
{{ warnf "page.html called %d times" math.Counter }}
|
|
```
|
|
|
|
```text
|
|
WARN page.html called 1 times
|
|
WARN page.html called 2 times
|
|
WARN page.html called 3 times
|
|
```
|
|
|
|
Use this function to:
|
|
|
|
- Create unique warnings as shown above; the [`warnf`] function suppresses duplicate messages
|
|
- Create unique target paths for the `resources.FromString` function where the target path is also the cache key
|
|
|
|
> [!note]
|
|
> Due to concurrency, the value returned in a given template for a given page will vary from one build to the next. You cannot use this function to assign a static id to each page.
