Love this idea ❤️ Just some suggestions.
| <%- if @options.canonical_root -%> | ||
| <% context = klass if defined?(klass) %> | ||
| <% context = file if defined?(file) %> | ||
| <link rel="canonical" href="<%= canonical_url(context) %>"> |

Can this be included in the if statements above? Then we don't need the context conditions separately.

I've changed the implementation to use current instead of klass and file to simplify.
If I'd use the if statement I would need to add an else as well, resulting in adding the tag 4 times.
| content = File.binread("Klass/Inner.html") | ||
|
|
||
| assert_include(content, '<link rel="canonical" href="https://docs.ruby-lang.org/en/master/Klass/Inner.html">') | ||
| end |

Can we have another test for file pages?

Ah sorry, didn't push my changes.
Should be present now.

Outdated

I prefer making canonical_url taking the path already instead of a nilable context. It'll likely be easier to maintain and debug.

I've changed the implementation to take the path instead.

I’ve changed the implementation to have less logic in the template and moved it to RDoc::Markup. This will allow other templates to use it as well. |

@p8 can you rebase and push again? I'll merge it then, thx |
Currently, search engines don't know which version to show for API documentation. For example, searching for "ruby string" in Google will show the documentation for Ruby 2.0 `https://docs.ruby-lang.org/en/2.0.0/String.html` as the top result (for docs.ruby-lang.org). The canonical URL link tag will allow us to set the preferred version: > The canonical URL link tag defines the preferred URL for the current > document, which helps search engines reduce duplicate content. https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Attributes/rel#canonical For example, for the official Ruby documentation we can add the following to `.rdoc_options`. ```yaml canonical_root: https://docs.ruby-lang.org/en/master ``` This will add the canonical URL link tag to relevant pages.

Thanks @st0012 ! I've rebased to master. |
v6.13.1...master We can then bump `ruby/ruby`'s RDoc to [set canonical url](#1354).
|
I've applied this to Ruby's master doc and 3.4 doc. |

@st0012 Thanks! |
