JRuby vs Markdown: What are the differences?

JRuby: A high performance, stable, fully threaded Java implementation of the Ruby programming language. JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java. The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information; Markdown: Text-to-HTML conversion tool/syntax for web writers, by John Gruber. Markdown is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML.

JRuby and Markdown can be categorized as "Languages" tools.

"Java" is the top reason why over 7 developers like JRuby, while over 345 developers mention "Easy formatting" as the leading cause for choosing Markdown.

JRuby is an open source tool with 3.32K GitHub stars and 830 GitHub forks. Here's a link to JRuby's open source repository on GitHub.

Asana, Code School, and GoSquared are some of the popular companies that use Markdown, whereas JRuby is used by Groupon, Soundcloud, and Lookout. Markdown has a broader approval, being mentioned in 756 company stacks & 718 developers stacks; compared to JRuby, which is listed in 13 company stacks and 4 developer stacks.

    What are some alternatives to JRuby and Markdown?
    Ruby
    Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.
    Groovy
    Groovy builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. It makes modern programming features available to Java developers with almost-zero learning curve.
    Rails
    Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.
    Go
    Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
    PHP
    Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

    Jekyll is an open source static site generator (SSG) with a Ruby at its core which transform your plain text into static websites and blogs.

    It is simple means no more databases, comment moderation, or pesky updates to install—just your content. As said earlier SSG uses Markdown, Liquid, HTML & CSS go in and come out ready for deployment. Lastly it's blog-aware permalinks, categories, pages, posts, and custom layouts are all first-class citizens here.

    For Stack Decisions I needed to add Markdown in the decision composer to give our users access to some general styling when writing their decisions. We used React & GraphQL on the #Frontend and Ruby & GraphQL on the backend.

    Instead of using Showdown or another tool, We decided to parse the Markdown on the backend so we had more control over what we wanted to render in Markdown because we didn't want to enable all Markdown options, we also wanted to limit any malicious code or images to be embedded into the decisions and Markdown was a fairly large to import into our component so it was going to add a lot of kilobytes that we didn't need.

    We also needed to style how the markdown looked, we are currently using Glamorous so I used that but we are planning to update this to Emotion at some stage as it has a fairly easy upgrade path rather than switching over to styled-components or one of the other cssInJs alternatives.

    Also we used React-Mentions for tagging tools and topics in the decisions. Typing @ will let you tag a tool, and typing # will allow you to tag a topic.

    The Markdown options that we chose to support are tags: a, code, u, b, em, pre, ul, ol, li.

    If there are anymore tags you'd love to see added in the composer leave me a comment below and we will look into adding them.

    I needed to make stack decisions accept a subset of Markdown, similarly to sites like Reddit or Stack Overflow.

    I used the redcarpet Ruby gem for parsing, and Rails' sanitize helper made it very easy to only allow certain tags: links, bold, italics, lists, code blocks, paragraphs.

    Problem solved! #StackDecisionsLaunch

    More than year ago I was looking for the best editor of Angular 2 application and I've tried Visual Studio Code and Atom. Atom had performance issues that put me off completely to use it again. Visual Studio Code became my main editor #Typescript files (and partly editor of #Java files). I'm happy with Visual Studio Code and I've never look back on Atom. There wasn't any reason to try Atom again, because Visual Studio Code fulfills my requirements very well. I use it for editing of TypeScript, #HTML, #Sass, JSON, Docker and Markdown.

    We’re using Markdown parsers for Reviews, Blog Posts, and Stack Description (the text you’re reading right now). We’re using Bootstrap Markdown for content input (except for reviews) and RedCarpet for rendering in certain places.

    Markdown represents a highly portable and lightweight text formatting. I had converted all of my Wordpress posts to Markdown prior to migrating over to Jekyll and eventually to Hugo. The fact that many generators support Markdown means that my content remains portable regardless of the platform/engine I use.

    What you see is not what you get, never it is.

    Documentation is better in Markdown format. You don’t need anything special to read it.

    It is compact, portable, comparable.

    Markdown is my text file format of choice.

    Because it is almost an effortless markup language without ever having to write an HTML tag. Of course, you'll want to use it in environments that make it look pretty (GitHub, etc.)
