InlineViewComponent

This gem allows your ViewComponents to define template strings within the class definition. You should be able to use any templating language your rails app supports (ERB, HAML, Slim...). There's also custom syntax highlighting for heredoc templates for Sublime Text.

Include the InlineViewComponent mixin and then specify your template string with template(string). Be sure to delete your component's external template file or ViewComponent will raise an error.

class ErbComponent < ViewComponent::Base
  include InlineViewComponent

  def message
    "Hello World!"
  end

  template <<~ERB
    <p> <%= message %> </p>
  ERB
end

class HamlComponent < ViewComponent::Base
  include InlineViewComponent

  def message
    "Hello HAML!"
  end

  template <<~HAML, :haml
    %p= message
  HAML
end

You can provide any template format you have installed as an optional second argument to the template method

  template <<~SLIM, :slim
    h1 Hello World!
  SLIM

Add this line to your application's Gemfile:

gem 'inline_view_component'

And then execute:

$ bundle

Or install it yourself as:

$ gem install inline_view_component

Syntax highlighting for Sublime Text is available. Download this file and add it to your Sublime User package. Then open your ruby files in the Ruby (Custom) syntax (or choose View -> Syntax -> Open All with current extention as... to use it automatically).

To get syntax highlighting to work use ERB, HAML, or SLIM as the delimiter for your heredoc string e.g.

template <<~HAML, :haml
  %h1 A really great template
HAML

This is an early release. Contributions are welcome!

• add syntax highlighting for more editors (VS Code, vim, ...)
