Breaking

• {{% badge style="warning" title=" " %}}Breaking{{% /badge %}} This release removes the themes implementation of ref/relref in favor for Hugo's standard implementation. This is because of inconsistencies with the themes implementation. In advantage, your project becomes standard compliant and exchanging this theme in your project to some other theme will be effortless.

  In a standard compliant form you must not link to the *.md file but to its logical name. You'll see, referencing other pages becomes much easier. All three types result in the same reference:

  Type	Non-Standard	Standard
  Branch bundle	configuration/options/_index.md	configuration/options
  Leaf bundle	configuration/options/index.md	configuration/options
  Page	configuration/options.md	configuration/options

  If you've linked from a page of one language to a page of another language, conversion is a bit more difficult but Hugo got you covered as well.

  Also, the old themes implementation allowed refs to non-existing content. This will cause Hugo's implementation to show the error below and abort the generation. If your project relies on this old behavior, you can reconfigure the error handling of Hugo's implementation.

  In the best case your usage of the old implementation is already standard compliant and you don't need to change anything. You'll notice this very easily once you've started hugo server after an upgrade and no errors are written to the console.

  You may see errors on the console after the update in the form:

  ERROR 2021/11/19 22:29:10 [en] REF_NOT_FOUND: Ref "configuration/options/_index.md": "hugo-theme-relearn\exampleSite\content\_index.en.md:19:22": page not found
  

  In this case, you must apply one of two options:

  1. Start up a text editor with regular expression support for search and replace. Search for (ref\s+"[^"]*?)(?:/_index|/index)?(?:\.md)?(#[^"]*?)?" and replace it by $1$2" in all *.md files. This is the recommended choice.

  2. Copy the old implementation files theme/hugo-theme-relearn/layouts/shortcode/ref.html and theme/hugo-theme-relearn/layouts/shortcode/relref.html to your own projects layouts/shortcode/ref.html and layouts/shortcode/relref.html respectively. This is not recommended as your project will still rely on non-standard behavior afterwards.
