# What this PR does
The `docs/reference` shortcode supports contextual destinations and
version inference.
`<ONCALL VERSION>` is inferred to match the version of the documentation
set. For example, the inferred version for the page
/docs/grafana/oncall/latest/get-started/ is "latest". It can also be
overriden using front matter.
Given the same page, but with the additional front matter
`oncall_version: next`, the variable is substituted with "next" rather
than "latest".
Contextual destinations are achieved using repeated labels in the
shortcode inner text. The format is [<LABEL>]: "<PAGE PATH PREFIX> ->
<HUGO REFERENCE>".
- _`<LABEL>`_ matches the reference style link label used in the rest of
the text.
- _`<PAGE PATH PREFIX>`_ is matched against the page during the
production build. If the match is successful, the destination that is
used is _`<HUGO REFERENCE>`_. The first matching prefix is used, not the
longest matching prefix.
## Which issue(s) this PR fixes
- Broken links due to ambiguous relref resolution. Any relref parameter
that does not start with either `/`, `./`, or `../` can resolve
ambiguously and is resulting in broken link behavior on the current
site.
- Broken links in Grafana Cloud. We mount OnCall documentation in
Grafana Cloud. In https://github.com/grafana/website/pull/13872 the
location will become /docs/grafana-cloud/alerting-and-irm/oncall. This
PR is intended to be merged alongside that PR.
