Can you create a blog or docs with high_voltage?

[collimarco]

I am looking for something like Jekyll, but directly embedded inside the Rails app.

The idea is to have a folder blog with all the blog posts. Each post would also have a front matter.

Is there any way to iterate on the blog posts?

Ideally you would read each file like it was a row in a database, so that you have a author, category, date, etc. from the front matter for each post, then you can display the index of posts or a category or a specific post.

Can you do that with this gem? Do you already have a similar approach for that (blog, docs, etc.) or I need to build from scratch?

I think you could get that working, but you need a way to make rails render markdown first. Here's one approach.

I think you could get that working, but you need a way to make rails render markdown first. Here's one approach.

I had something like this implemented and it worked perfectly. I can dump markdown files (with erb) in my pages folder without issues. Here are my steps:

1. Install the RedCarpet Markdown Gem ($ gem install redcarpet)
2. Add a file to your app/config/initializers, mine is called markdown_template_handler.rb,
3. Write a ruby file that calls the redcarpet gem on markdown files using the register_template_handler function. Here is a copy of mine, but please note that I have it wrap generated markdown in the tailwindcss prose class for styling.

Also DANGER, I am the only author, so I have erb available on all markdown files. You may want create a second file format like mderb so that you can limit when markdown can have erb:

# app/config/initializers/markdown_template_handler.rb
require 'redcarpet'

class CustomMarkdownRenderer < Redcarpet::Render::HTML
  def postprocess(full_document)
    "<div class=\"prose prose-xl prose-img:rounded-xl prose-headings:underline prose-a:text-blue-600 \">#{full_document}</div>"
  end
end

class MarkdownTemplateHandler
  def erb
    @erb ||= ActionView::Template.registered_template_handler(:erb)
  end

  def call(template, source)
    compiled_source = erb.call(template, source)
    "Redcarpet::Markdown.new(CustomMarkdownRenderer.new).render(begin;#{compiled_source};end.to_s).html_safe"
  end
end

ActionView::Template.register_template_handler(:md, MarkdownTemplateHandler.new)
