This gist shows how I'm using Rouge to highlight individual lines of code. On top of the existing syntax highlighting.

I'm using Sitepress which uses markdown-rails under the hood. But this should be applicable to any application rendering markdown with Redcarpet - sub out ApplicationMarkdown as your renderer.

Append @[] when setting the language in a fenced code block to highlight lines of code. Dashes will cover the range, inclusive. Commas will highlight each line.

Examples:

```swift@[4-6]

import Foundation

enum Environment: String {
    case development, staging, production
}

extension Environment {
    static var current: Environment {
        if isAppStore {
            return .production

struct ExampleView: View {
    var body: some View {
        VStack(spacing: .default) {
            HStack(spacing: .xl) {
                Text("Is this crazy?")
                    .font(.system(size: .lg, weight: .semibold))
            }
        }
    }
}

<div data-controller="toggle">
  <button type="button" data-action="toggle#toggle">Toggle</button>

  <div data-toggle-target="element" data-expanded="false" class="data-[expanded=false]:hidden">
    Here is some toggle-able content!
  </div>
</div>

Goal: send a notification when a customer subscribes, churns, pauses, etc.

This is the barebones working version. Is there something I'm missing in Pay that could help with this?

If not, happy to clean it up and submit a PR if it will be valuable for others.

Note: This first-pass implementation is ugly, but the tests pass. There is obviously a lot to improve in terms of code quality, but my bigger focus is on the direction and idea.

Turbolinks + Turbo Native - Generic form handling with Stimulus

These three files show how to handle forms with (legacy) Turbolinks in your Rails app with the new Turbo Native adapters.

1. The Rails controller renders the form partial with an :unprocessable_entity status when encountering a form validation error
2. The form is submitted via AJAX (local: false or remote: true depending on your Rails version)
3. This is caught via the ajax:error->form#onError Stimulus action
4. The Stimulus controller replaces the form's contents with the server-sided rendered HTML
5. The native app is informed when the redirect occurs on a succesful submission
