Spaces inserted into code

[josephzidell]

Using

    pipeline = HTML::Pipeline.new [
      HTML::Pipeline::MarkdownFilter,
      HTML::Pipeline::SyntaxHighlightFilter
    ]

produces code that has 10 spaces prepended to every line after the first, including an extra line with 10 spaces at the end.

This

```css
@media (max-width: 992px) {
    #contact_email{ display: none; }
}

produces

@media (max-width: 992px) {
              #contact_email{ display: none; }
          }
          // 10 spaces at end

Hi @josephzidell!

Please gist your raw markdown document, so I can try to reproduce. Thanks.

[josephzidell]

Sure. It's a blog post https://gist.github.com/josephzidell/8816548

@josephzidell I'm sorry, but I don't see the extra white space. It's not in your gist. I created a testing gist, and the CSS looks good. Maybe, your implementation is adding the white space?

[josephzidell]

@simeonwillbanks Thanks for your help. How would I determine if my "implementation" is adding the white space?

[simeonwillbanks]

@josephzidell Let's try a few things:

1. Double check your CSS styles; is a padding or a margin being added?
2. Add result[:output].to_s to your gist
3. Run bundle exec nokogiri -v and paste output into this issue
4. Paste more relevant implementation code into this issue

Thanks!

[josephzidell]

@simeonwillbanks Thanks so much for your help. I trimmed down the problem to just a single line.

1. It's actual spaces, highlightable via a mouse

2. Here's a new gist with everything.

3. nokogiri version

   $ bundle exec nokogiri -v

   Nokogiri (1.6.1)

@josephzidell Thanks for the info, but I'm still unable to reproduce.

Your markdown is sent to GitHub::Markdown. Maybe it's the source of the issue? Please try this in your rails console:

markdown = @post.body_markdown
pipeline = HTML::Pipeline.new [HTML::Pipeline::MarkdownFilter]
pipeline.call(markdown)[:output].to_s
#=> "<pre lang=\"html\"><code>&lt;a href=&quot;mailto:[email protected]?subject=Hi!&amp;amp;amp;body=Either type the email address or use the form. Thanks!&quot;&gt;&lt;/a&gt;\n</code></pre>" 
GitHub::Markdown.to_html(markdown, :gfm)
#=> "<pre lang=\"html\"><code>&lt;a href=&quot;mailto:[email protected]?subject=Hi!&amp;amp;amp;body=Either type the email address or use the form. Thanks!&quot;&gt;&lt;/a&gt;\n</code></pre>\n"

This is still an issue, that I'd like to get fixed.

Due to the length of time here, I actually implemented the web app in PHP instead of rails :( to get around this problem.

Followed @simeonwillbanks's instructions: no extra spaces there.

[simeonwillbanks]

@josephzidell If you tried my two examples and you didn't see extra spaces, it sounds like html-pipeline isn't the culprit. Maybe the issue is with raw?

[josephzidell]

After some playing around, the issue certainly seems to be with raw. So it's not an issue with html-pipeline.

The question is: what to do?

[jch]

@josephzidell you might want to try your question over at stackoverflow.com too

[simeonwillbanks]

@josephzidell I second trying on stackoverflow.com.

[josephzidell]

Will do. Thanks, guys. Here's a link to the question. Thanks, guys!

[josephzidell]

As you can see, it's actually a HAML issue. Thanks again.

[simeonwillbanks]

Good to know. Thanks!
