Bug in syntax-highlighting? - pandoc 2.10.1

Bug in syntax-highlighting? - pandoc 2.10.1

Hi,

I try to use my own syntax-lighting with pandoc and target format HTML.

Coloring works, so far as I have tested it. However, the anchors don't work 
as expected from the documentation.

For one, the doc says:

The numberLines (or number-lines) class will cause the lines of the code 
block to be numbered, starting with 1 or the value of the startFrom 
attribute

This also works as described. In particular: no class numberLines means no 
numbers.

The doc also says:

The lineAnchors (or line-anchors) class will cause the lines to be 
clickable anchors in HTML output.

This does not work, as I understand it. pandoc always produces anchors, 
independent of whether the class lineAnchors is present of absent. To me, 
this is a nuisance, because I do not want anchors. Is there a way to 
prevent pandoc from creating anchors or is this a bug?

Note: pandoc will always create anchors, even without line numbers. Even 
this is ugly, because my browser -- firefox -- shows selectable dots at the 
beginning of each line.

Thanks in advance
Karl

As a workaround, you can use the following CSS to hide the anchors:

    <style>
      pre > code.sourceCode a {
        display: none;
      }
    </style>

My assumption was that empty anchors are invisible and harmless.
I did not know that some browsers display them as dots.  It seems
like non-standard behavior -- do any other browsers do this?

Hi Albert,

thanks for your answer.

 This would only help with empty anchors, however not in case I am also 
using line numbers (which I occasionally do in code blocks).

However, it is pointing into the right direction. The css pandoc is 
inserting through the variable $highlighting-css$ is colliding with my own 
css in other respects, so I will remove it from the template altogether and 
adjust my own css. As long as I am only dealing with target format html, 
this will even save me from the need to define my own themes file. The 
latter would only be an indirect way to specify the css.  

Regards
Karl
