Turns out showdown requires strict tabling, seen in https://github.com/showdownjs/showdown/issues/666

How do I display a markdown table on a website with go backend?
So you're going to need a Markdown parser that produces HTML. But there's a question of where is the data coming from and where you you want to process it? If it's going to be all on the frontend like a text editor, use a JS library for it (a quick google search produces ShowdownJS)

Docusaurus first impression and stealing like an open sourcer
Previously, I was required to implement the markdown support manually which meant that the use of public libraries was prohibited. My tool could only support limited styling elements such as header1, header2, links, bold and italics, but now I can finally let my tool have a full markdown support by using Showdown.

I made a full-stack portfolio site using Next.js and Tailwind!
The first two ages are very heavy on content so I decided to use markdown and tailwind’s typography plugin for styling. I also used showdown to fetch the markdown and turn it into HTML. The code for the above can be found on the site’s GitHub repository.

Working on a no-code data notebook. You can quickly pull data from platforms like Stripe and do complex analysis without writing SQL, all within a Notion-style interface. Thoughts?
I'm using https://github.com/showdownjs/showdown for the core rendering-markdown functionality, with a bunch of additional listeners etc on top of it to fit it into the notion-style UX! Hope that helps :)

Hosting free Strapi CMS on Heroku [Building Personal Blog Website Part 1]
As you can see the content is returned as markdown - it's much more efficient to send the data this way, but in our frontend app we'll need to convert it to HTML. We'll probably use something like Showdown.

A Colorful Textarea
Adding syntax highlighting to an input field can be a hard task. supports neither styling of individual characters or words, nor HTML tags within itself, there is no fully supported native solution for that. Most editors work with
contenteditable
to actually render a fully marked up code snippet and let the user edit its content. This requires a lot of work to get it accessible (as in restore all the native functions of a textarea) and still adds a lot of complexity.
If you don't want that and are just looking for a quick, dead-simple solution: Here's how to colorize a textarea.Solution
The trick is to separate the input element from the displayed one. We can't color the content of a textarea, but we can make it invisible and replace it with marked up content. This works with monospaced fonts and fonts with a uniform width across normal, bold and italic characters. I'm using this for code and markdown, so that's perfectly acceptable for me. We also need to be careful to match the dimensions of the textarea exactly while only using font-relative units like
em
, to ensure that the highlight element scales well with the invisible textarea. The cursor is still in the textarea's context, while the text itself is rendered in the highlight element. We want to match every character of the textarea to match the highlighted one on a pixel-perfect basis.I also need to auto-resize my textarea. Since textareas usually scroll vertically, that would mess up the position matching with the highlight element. Auto-resizing seems like a graceful workaround to me.
The highlghting itself would work with every code parser. I'm using highlight.js to convert markdown to syntax-highlighted HTML. I listen for content changes in the textarea and parse new rendered code on every input. To counter the worst performance hits, I'll just use
requestAnimationFrame
. Debouncing isn't an option here, because the user would only see what they've written after they've finished typing. That'd be very poor UX.Demo
Note that this example also displays the rendered Markdown in a separate element. I'll use the change listener that I already have to splice in a Markdown renderer: Showdown.
Pros
- as accessible as a textarea
- is a progressively enhanced feature
- can be styled exactly to your needs
- dead simple solution compared to a rich text editor
Cons
- has performance issues with large texts (as do textareas in general)
- works only with monospaced fonts
- works only with auto-sizing textareas

Vala Programming Language
> it was designed to resemble C#
I actually first heard of Vala just a few days ago when I was looking at a C#-related PR[1] for highlight.js:
> This fails the tests as the Vala default.txt is recognized now as C#. However, Vala is very close in syntax to C#, and the default.txt also seems to be valid C# so not sure what to do about this.

Build a simple code editor
Luckily, implementing syntax highlighting in our simple code editor is easy with the use of external libraries. There are several JavaScript libraries available, such as Prism and Highlight.js. For our editor, we'll use Prism since it's easy to use and supports a wide range of programming languages.

Is copying from open source projects stealing?
My search for a third-party syntax highlighter brought me to highlight.js. ctil converts text (.txt) and Markdown (.md) to generated HTML (.html) files, so I want the generated HTML files to support syntax highlighting. highlight.js can be used as HTML Tags by using a Content Delivery Network, CDN, so I was able to add highlight.js by adding the following lines to the generated HTML files:

building a basic markdown editor: unified, trees and data
The real magic is what happens once you generate the syntax trees; at that point, you can modify them with the existing plugins (or make you own, if you really want to). For instance, I use a plugin to add specific css classes to certain elements so they integrate better with the visual design of the website another to add code highlighting with highlight.js and some others for generating a js object from the frontmatter of a Markdown file and to add support for Github flavored Markdown. I could do a lot more with these, like add support for videos, embeds and more, but for now this is enough for a simple preview.

HTML5 - Text markup elements
pre is for a block of preformatted text, so spaces are preserved, and the font can be monospaced. Another element is code for programming codes. Notice that code doesn't offer code highlighting; for this, use JavaScript + CSS code, like Highlight.js.
