What version of rails docs did you install? I've tried the 7.0 and 6.1 one and both work correctly. It looks similar to #58. Could you give me more information, OS, neovim, nvim-treesitter and curl version.

[ttitoo]

Rails 6.1 can be installed successfully, but no luck with 7.0 and 7.1

By the way, great plugin!

[jweslley]

I got the same outcome as @ttitoo . This plugin is awesome 🚀🚀🚀

My setup is:
OS: MacOS Sonoma 14.2.1 (23C71)
neovim: v0.9.5
nvim-treesitter: commit=10d79b5dbbdffc3edf307b189284fb62e2e79a3e
curl: v8.4.0

Same. I was able to install ruby-3.3, html, css, typescript, and taildwindcss just fine. But rails-7.0 and rails-7.1 both give me this:

<p>Action Cable seamlessly integrates <a href="https://en.wikipedia.org/wiki/WebSocket">WebSockets</a> with the rest of your Rails application. It allows for real-time features to be written in Ruby in the same style and form as the rest of your Rails application, while still being performant and scalable. It's a full-stack offering that provides both a client-side JavaScript framework and a server-side Ruby framework. You have access to your entire domain model written with Active Record or your ORM of choice.</p>
<h2 id="terminology"><a class="anchorlink" href="#terminology">2 Terminology</a></h2>
<p>Action Cable uses WebSockets instead of the HTTP request-response protocol. Both Action Cable and WebSockets introduce some less familiar terminology:</p>
<h3 id="terminology-connections"><a class="anchorlink" href="#terminology-connections">2.1 Connections</a></h3>
<p><em>Connections</em> form the foundation of the client-server relationship. A single Action Cable server can handle multiple connection instances. It has one connection instance per WebSocket connection. A single user may have multiple WebSockets open to your application if they use multiple browser tabs or devices.</p>
<h3 id="consumers"><a class="anchorlink" href="#consumers">2.2 Consumers</a></h3>
<p>The client of a WebSocket connection is called the <em>consumer</em>. In Action Cable, the consumer is created by the client-side JavaScript framework.</p>
<h3 id="terminology-channels"><a class="anchorlink" href="#terminology-channels">2.3 Channels</a></h3>
<p>Each consumer can, in turn, subscribe to multiple <em>channels</em>. Each channel encapsulates a logical unit of work, similar to what a controller does in a typical MVC setup. For example, you could have a <code>ChatChannel</code> and an <code>AppearancesChannel</code>, and a consumer could be subscribed to either or both of these channels. At the very least, a consumer should be subscribed to one channel.</p>
<h3 id="subscribers"><a class="anchorlink" href="#subscribers">2.4 Subscribers</a></h3>
<p>When the consumer is subscribed to a channel, they act as a <em>subscriber</em>. The connection between the subscriber and the channel is, surprise-surprise, called a subscription. A consumer can act as a subscriber to a given channel any number of times. For example, a consumer could subscribe to multiple chat rooms at the same time. (And remember that a physical user may have multiple consumers, one per tab/device open to your connection).</p>
<h3 id="pub-sub"><a class="anchorlink" href="#pub-sub">2.5 Pub/Sub</a></h3>
<p><a href="https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern">Pub/Sub</a> or Publish-Subscribe refers to a message queue paradigm

I do also see that rails-6.1 installs fine. Seems like something is wrong with the HTML.

The error message shows that this file has no single root node. It's just a bunch of siblings because it gets included into a larger HTML file on api.rubyonrails.org. Perhaps this is the issue?
