The counter is global for both monolingual and multilingual projects, and its initial value for each build is 1.

go-html-template
{{ 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.
