Add Highlight Syntax Highlighting to MarkdownEditing

[mmerline]

If possible, please add Highlight syntax to MarkdownEditing.

In apps like iA Writer, “You can use double equals signs to highlight text”. Two equal signs (==) before and after the words highlights the text in the app and is rendered as <mark>[highlighted text]</mark> when exported as HTML.

I recognize this is very similar to one aspect of the Critic Markup spec included in the Markdown Editing package, the {== highlight==}{>> comment <<} inline critic markup, but that markup renders as <span class="critic criticcomment inline" data-comment=" comment ">[Critic Markup highlight text]</span>. This would be complementary.

Thanks. Please let me know if you have any questions or if I missed some required information.

Note that's not a CommonMark nor Github flavoured markdown feature.

As long as no bold/italic or other content is to be supported within the highlighted region, implementation should however be rather simple.

Added by v3.1.14

@deathaxe, thank you for implementing this. After updating the package it appears the standard MarkdownEditing themes aren't providing syntax highlighting for the added ==highlight== code. Something I need to change on my end?

You can customize them via UI: Customize Color Scheme and add your own user-defined highlighting rules, though.

{
    "name": "Markup: Highlight",
    "scope": "markup.highlight",
    "foreground": "black",
    "background": "yellow"
},

Is this the correct way to add that code to the default template?

Yeah.
