Can I eliminate newlines between elements in generated HTML?

Can I eliminate newlines between elements in generated HTML?

[Matt Haggard]

[-- Attachment #1.1: Type: text/plain, Size: 1421 bytes --]

I have a filter that adds elements to code blocks (for bolding, italics, 
etc.).  We go markdown -> html -> pdf and have noticed that sometimes there 
is an extra erroneous space between these custom elements in the final PDF. 
 This breaks copying and pasting.

It's because pandoc adds newlines between some elements in the generated 
HTML.  This shows and example:

echo -e 
'<div><pre><code>hello</code></pre><pre><code>world</code></pre></div>' | 
pandoc -t html5

<div>

<pre><code>hello</code></pre>

<pre><code>world</code></pre>

</div>


Is there a way I can get the output of the above to instead be this?  (or 
even match the original input string)

echo -e 
'<div><pre><code>hello</code></pre><pre><code>world</code></pre></div>' | 
pandoc -t html5

<div>

<pre><code>hello</code></pre><pre><code>world</code></pre>

</div>

Thank you!

Bah... google groups messed up the newlines, but maybe you get the idea?

[Matthew Pickering]

Can you please describe what you are doing? You mention that you're
going markdown -> html -> pdf (why?)

The answer to your question is that pre is a block level element and
pandoc inserts newlines after each block from what I remember.

Re: Can I eliminate newlines between elements in generated HTML?

[Matt Haggard]

[-- Attachment #1.1: Type: text/plain, Size: 3487 bytes --]

I've found a solution that I like (and doesn't involve complicating pandoc).

    pip install htmlmin
    echo -e 
'<div><pre><code>hello</code></pre><pre><code>world</code></pre></div>' | 
pandoc -t html5 | htmlmin -s

To answer your question:

We write markdown by hand, which contains code blocks full of custom 
elements (for highlighting).  Our custom format is <r:b>bold</r:b> within 
the codeblock.  Using a pandoc filter, those custom blocks get turned into 
this HTML:

    <pre class="bold"><code>bold</code></pre>

We then use http://www.princexml.com/ to convert from HTML to a PDF.

Thanks!

We're on 1.15.0.6 which doesn't have --wrap=none but DOES have --no-wrap, 
which works.  Thank you!  (I don't really think of this is case as 
"wrapping" so didn't think to search for that)
