Thanks for this plugin. And a happy new year!

Good idea. Also good to consider bold+italics, escaping, different markup styles etc from the start.

[chrisgrieser]

One thing that occurred to me just now is that the emphasis object could maybe also include ==highlights== and ~~strikethrough~~? (though the latter is strictly speaking not really "emphasis")

[stevenxxiu]

Strikethrough and highlights added! I didn't even know Markdown had highlights.

[chrisgrieser]

readme needs to be adjusted for the changes, otherwise it looks good to me

[stevenxxiu]

Readme updated.

[chrisgrieser]

I think you accidentally ran a formatter on the table? cause the whole table is now included in the diff. Could you undo that formatting to keep the diff history clean?

[stevenxxiu]

Ah I just updated the table to align the columns. There's quite a few things that count as emphasis and there wasn't enough space.

[chrisgrieser]

oh, I see. Yeah then it's fine. Thanks for the PR!
