enhance the underline code block feature to support more languages

[fdaguin]

Is your feature request related to a problem?

The Error/Warning Underline (#49) feature is limited to "languages supporting /* ... */ or (* ... *) comment syntax".

Describe the solution you'd like

I'd like this feature to support languages outside of this limitation, specifically languages with no inline-comment support.

Could this maybe be achieved like the Code Highlights feature where the symbol "is pre-processed by codedoc before syntax highlighting and removed from the code"?

Can you give an example of such a language?

[fdaguin]

Sure, here is a quick list of languages I have in mind:

• languages with no inline-comment:
  • Python
  • Ruby
  • Perl
  • PowerShell
  • YAML
• language with no comment support at all:
  • JSON
