Sometimes when I’m working with Markdown in a Rails app, I’ll be using different sets of redcarpet flags for different types of content. For example, I have images and links turned on for blog posts, but turned off for comments. Keeping track of all the variations can be difficult. I now prefer to define a set of render “modes” that I can pass into a single renderer class, with clear comments for what is allowed and disallowed.
def render_markdown(content, mode)
