It must a pain to make a Rich Textbox (lemmy.ml)

It must be a pain to make a text box with the ability to add bold, italic, heading, etc. you know? All the bold text, italics, and headings would need to be saved in a database column to be retrieved later in their correct positions.

I don't know, I am doing internship learning C# ASP (started 2 months ago), and just got a "Shower Thought" while making an edit post function.

If I wanted a WYSIWYG field I'd probably still use markdown. I could add the buttons to properly inject markdown symbol and use a JS markdown renderer for the text field. Tbh I'd be amazed if there weren't at least a dozen out-of-the-box packages that included a live rendered text area with a widget array.

In this instance I'm not advocating for markdown as a user interface but just using it as a quick and dirty markup language. Be aware that if you turn to HTML, you'd be adopting responsibility for a lot of non-trivial security issues. If the customization went beyond markdown (into, for instance, fonts) you'd need a more complex solution so you'd likely want to investigate other tag or boundary marker based markup languages out there. Markdown is just simple and has ten billion implementations out there.

Probably not. Having actually played with making a WYSIWYG editor as a learning project markdown is too simplistic for the formatting needs of any non-trivial text editing, as a serialized storage format.

You almost always end up back with your own data structure that you serialize into something like XML for storage. Or you end up supporting HTML or non-spec compliant syntax in your markdown.

And if you care about performance, you're not actually working with XML, HTML, or Markdown in memory. You're working with a data structure that you have to serialize/deserialize from your storage format. This is where markdown becomes a bit more tedious since it's not as easy to work with in this manner, and you end up with a weird parsing layer in-between the markdown and your runtime data structures.

The commenter that's downvoted is more correct than not IMHO (Also why are we downloading discussions??). Markdown is ill suited for "most WYSIWYG needs". It tends to get augmented with XML or custom non-spec compliant syntax. The spec poorly supports layout (columns, image & media positioning, sizing...etc) and styling (font color, size, family, backgrounds...etc)
