Markdown syntax highlighting for ~~text with strikethrough~~ and task-items

[maranomynet]

It would be very nice to see ~~text with strikethrough~~ being greyed out (or somehow highlighted) in source mode (not "Preview" mode) – like _italic_ and **bold** text is.

Also greying out finished/checked * [x] task-items would be sweet.

I am interested to work on this one. I checked some documentation but I can't find yet how to add strikethrough style because this fontStyle seems to be not supported by vscode yet.
Does somebody know where I can add this?

strikethrough is not something TM grammars support, so I would not recommend deviating from TM grammars/themes with custom font properties such as strike-through in TM themes.

This could perhaps be implemented via editor decorations. Strike-through could be useful for other programming languages, for rendering deprecated method names, etc..

A workaround: using extension TODO Highlight with this settings

"todohighlight.keywordsPattern": "~~.+?~~",
"todohighlight.defaultStyle": {
    "color": "none",
    "backgroundColor": "none",
    "textDecoration": "line-through"
}
