Arc vs Markdown: What are the differences?

Arc: A dialect of the Lisp programming language developed by Paul Graham and Robert Morris. Arc is designed for exploratory programming: the kind where you decide what to write by writing it. A good medium for exploratory programming is one that makes programs brief and malleable, so that's what we've aimed for. This is a medium for sketching software; 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.

Arc and Markdown belong to "Languages" category of the tech stack.

Asana, Code School, and GoSquared are some of the popular companies that use Markdown, whereas Arc is used by Helpful, Cask, and Icalia Labs. Markdown has a broader approval, being mentioned in 756 company stacks & 718 developers stacks; compared to Arc, which is listed in 7 company stacks and 6 developer stacks.

      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鈥攋ust 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.

      #StackDecisionsLaunch

      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.

      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鈥檛 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.)
