Herb: Powerful and seamless HTML-aware ERB parsing and tooling

Thanks, confusion about the application and the intended use cases seems to be a common issue among other comments.

Initially thought it was an addon (or JS lib) that allowed for using Ruby as an embedded client-side scripting language that would parse in-line Ruby in the HTML.

Clearer once I realized it was closer to PHP or similar language usages.

Second also to the recommendation about a quick definition of ERB (Embedded RuBy). Had to look it up.

A few practical examples of what an actual user might want to do with HTML + ERB could be helpful.

  - Client characteristics customization
  - Previous use history customization
  - The database Create, Read, Update, and Delete cycle using Herb
  - A basic Content Management System example
  - A basic e-commerce example
  - A basic RESTful API example

Thanks for that, I'm used to ERB referring to Epic Rap Battles of History.

This is something you could do with tree-sitter https://tree-sitter.github.io/tree-sitter/

I've been working with FastHTML and I have to say, I rather enjoy HTML-markup-as-objects.

It works pretty seamlessly and you get something like this:

    @app.post('/part/add')
    def create_part(part_number: str, name: str, description: str):
        p = Part(part_number=part_number, name=name, description=description)
        p.save()
        return (p,
            Input(placeholder="part number", id="part_number", hx_swap_oob='true'),
            Input(placeholder="description", id="description", hx_swap_oob='true'),
            Input(placeholder="name", id="name", hx_swap_oob='true'))

Phoenix (Elixir) has a very elegant version of that, without the need for the extra indent:

  <p :for={para <- paras} class={para.class} {para.attrs}>
    {para.text}
  </p>

I'm not seeing any ERB here. Whatever blend you came up with could be done in ERB which just combines Ruby with HTML.

Template engines like liquid are good for simpler use cases where you'd want your end users to write templates (who aren't programmers)

Yes, I believe tooling, linters and language servers for HTML plus ERB is what Herb is for.

I’m not sure it’s targeted towards those not familiar with Ruby... though yeah, at least mentioning it’s a templating engine would make it a lot easier to grasp.

(ERB is, I think, “embedded Ruby”, and it functions basically like old school PHP: you just insert pieces of Ruby code wrapped by <% .. %> or <%= .. %>: https://github.com/ruby/erb#recognized-tags)
