Sometimes there’s a couple things in a Markdown file that need to be cleaned up when it’s processed by Squarkdown. We can let Squarkdown know it needs to handle these through the clean field in the squark charm.
Braces
Curly braces {} pose an issue since Svelte and MDSveX use them for interpolation. This means when we try to import the .svx file, errors are raised as Svelte attempts to process the text inside as JavaScript.
To solve this, Squarkdown replaces all occurrences of { with &{ (and likewise for }). The double escape is necessary since { alone would still be rendered to { by MDSveX.
HTML Tags
Similarly, Svelte will try to process < and > as HTML tags, even if they aren’t used as such.
Line Breaks
This is something perhaps more specific to me, but Squarkdown can also remove extraneous line breaks if you have any. This replaces all instances of \n\n<br>\n\n in the source text with just \n\n.
I often use this to separate 2nd-level headings so that they render with a more distinct gap in Markdown, but in HTML this gap can be added with CSS so the extra line break is unnecessary.
