I have this regex /{([\d,-]+)}/ which is used to highlight lines in markdown and allows input in this format - {2,3-6,8}. Now, I wanted to include showLineNumbers prop in it too such as {2,3-6,8,showLineNumbers} and couldn't figure regex for this. I have tried this regex /{([\d\bshowLineNumbers\b,-]+)}/ but this still results in matched in following examples:

  • {1,2,3,ssssss}
  • {1,2,3,show}

But the expected value, should only have showLineNumbers prop one time, inside the curly brackets regardless of position. For eg: {showLineNumbers,3,5,6}, {3,5, showLineNumbers,6}, etcetera. should match the regex format. Where did I make a mistake in this format - /{([\d\bshowLineNumbers\b,-]+)}/ ?
