Hi,

I use a lot of comments in my markdown documents using the following format: [//]: # (Comment Text). In MarkdownEditing, comments in this format are rendered attractively with a bright background colour- as long as they do not have line-breaks. I’d like to edit this so that line-breaks do not affect the background highlighting for these comments.

More explicitly, comments of this form are highlighted:
[//]: # (This is a comment without a line-break.)
While comments of this form are not:
[//]: # (This is a comment with a line-break.)
I’d like to change this so that the highlighting is not affected by line-breaks.

I used Package Resource Viewer and Color Scheme Editor to try and edit the colour scheme. But, I’m not sure how and what to edit in the .tmTheme xml file.

looks like you’ll need to learn the tmLanguage file format and change this match regex pattern to a context that supports having the ) on a different line:

Thanks for the reply.

Can you help me with how the new regex pattern should look like?

I was planning to add a new syntax component with the following regex: ‘\A[//]: # ((.*?))\z’, and then adding it in the theme file. Which method would be easier?
