Is there a solution for highlighting CommonMark syntax in Vim?
No not yet.
Since Pandoc is headed the direction of standardizing on CommonMark, we have been discussing how to accomplish this for the vim-pandoc-syntax plugin. See issue #327 for relevant discussion. If anybody has input on this we’d love to hear it. A fully strict CommonMark compliant syntax plugin for VIM would be awesome, but it doesn’t look like it’s going to be easy to achieve.
Thank you for response, I supported your comments on GitHub.
