How to add custom method to replace text when already using CodeRay ?

[chrisvel]

This is my markdown rendering code:

def markdown(text)
    coderayified = CodeRayify.new(:filter_html => false,
                                  :hard_wrap => true)
    options = {
      :fenced_code_blocks => true,
      :no_intra_emphasis => true,
      :autolink => true,
      :strikethrough => true,
      :lax_html_blocks => true,
      :superscript => true,
      :tables => true,
      :highlight => true,
      :quote => true,
      :filter_html => false,
      :safe_links_only => true
    }
    markdown_to_html = Redcarpet::Markdown.new(coderayified, options)
    markdown_to_html.render(text).html_safe
  end

I want to add a custom method to replace some text, for example:

Links like

{-[another-link](https://goessomewhere.com)-}

should be replaced with

{<a href="https://goessomewhere.com" class="custom-link">another link</a>}

Does anyone have any idea how can I achieve this, especially now that I am already using a Renderer?
