I'm using the gem "redcarpet". And I have a markdown file. I want to be able to render it with some ruby variables. Something like this:

What's the proper way to do something like this? How can I pass and render a ruby variable?

推荐答案

您可以使用ruby中包含的erb库，但是您需要使用它:

You can use the erb library which is included in ruby, but you have to require it:

require 'erb'
require 'redcarpet'

input = File.read "./file.md"

markdown = Redcarpet::Markdown.new(Redcarpet::Render::HTML, autolink: true, tables: true)

output = markdown.render ERB.new(input).result(binding)

File.open("output.html", "w") { |f| f.write output }

您可以通过引用 redcarpet自述文件
