Pygments won't keep whitespaces

Issue #1382 new

created an issue

I've searched everywhere, and couldn't find a working solution or anything near that.

This is how my code in a template looks like:

        {% pygment 'java' %}
          private void registerUserEngageCustomer() {
  Customer customer = new Customer()
          .id("idfromyourdatabase") // id of your user
          .attr("email", "")
          .attr("name", "John Doe")
          .attr("loyalCustomer", true)
          .attr("age", 33)

          .register(customer, new UserEngage.RegisterCallback() {
              public void onSuccess(RegisterResponse response) {
                  Log.d(TAG, "onSuccess: " + response);
                  // user is registered and now you can send events via SDK

              public void onFailure(Throwable throwable) {
                  Log.e(TAG, "onFailure: ", throwable);
                  // try again - something went wrong
        {% endpygment %}

This is how my highlighted code looks like: Screen Shot 2017-09-28 at 11.14.33.png

CSS is fine btw.

    The template tag I'm using is taken from and modified HtmlFormatter like so:

    class PygmentsNode(template.Node):
        def __init__(self, lexer_name, nodelist):
            self.nodelist = nodelist
            self.lexer_name = lexer_name
        def render(self, context):
            content = self.nodelist.render(context)
            lexer_name = self.lexer_name.resolve(context)
            lexer = get_lexer_by_name(lexer_name)
            output = highlight(content, lexer,
                               HtmlFormatter(linenos=True, lineseparator='<br>',
            return mark_safe(output)
    def do_pygments(parser, token):
        Template tag that uses pygments to highlight code examples.
        Example usage:
            {% pygment 'python' %}
            def view_article(request, pk):
                return render(request, 'view_article.html', {
                    'article_id': get_object_or_404(Article, pk=pk)
            {% endpygment %}
        tokens = token.split_contents()
        nodelist = parser.parse(('endpygment',))
        return PygmentsNode(parser.compile_filter(tokens[1]), nodelist)

    So now it looks like: Screen Shot 2017-09-28 at 11.58.03.png

    But still missing white spaces
