Re: code block translation from latex to html

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

You need to provide us with more to go on.
By itself this input wouldn't produce highlighted code at all
(no language is specified).

Try this markdown sample:

~~~~~~
One:

``` {.haskell .numberLines}
let x = tail y in
    x <> y
```

Two:

``` {.haskell .numberLines}
x >>= y >>= z
```
~~~~~~

This works fine. Line numbers are generated. The line numbers are
links to the line (very useful!).  The two snippets generate separate
ids with links to separat elines.

Without the 'numberLines' class you don't get the line numbers,
and the lines are NOT links to themselves.

When converting from LaTeX/listings, you'll need to add the
numbers=left option to get numbering.

In your output

<span id="cb2-4"><a href="#cb2-4"></a><span class="dv">2</span> (<span 
class="dt">int</span>)  </span>

the line is not a link to itself (tested on browser just to make
sure); there is an <a> element but its content is empty since
you don't have a line number.
