django template comments crash unibeautify

[Somberland]

using django-template comments in html-files for example:

{% comment %} <button type='button' class='btn btn-secondary'>Secondary</button> {% endcomment %}

will break unibeautify.

HTML:
  beautifiers:
    - Pretty Diff
    # - JS-Beautify
  align_assignments: true
  indent_comments: true
  indent_style: tab
  indent_size: 1
  max_preserve_newlines: 4
  quotes: single
  brace_style: collapse
  break_chained_methods: true
  end_with_comma: false
  multiline_ternary: always-multiline
  end_with_newline: true
  force_indentation: false
  preserve_newlines: true
  indent_inner_html: true
  indent_scripts: normal
  newline_before_tags: []

Hi @Somberland. This looks to be an issue with prettydiff, I'll need to investigate further. Also, you're .unibeautifyrc.yml file is incorrect, you want:

HTML: 
  align_assignments : true 
  beautifiers : ["JS-Beautify", "Pretty Diff"] 
  brace_style : "collapse" 
  break_chained_methods : true 
  end_with_comma : true 
  end_with_newline : true 
  force_indentation : false 
  indent_comments : true 
  indent_inner_html : true
  indent_scripts : "normal" 
  indent_size : 1 
  indent_style : "tab" 
  max_preserve_newlines : 4 
  multiline_ternary : "always-multiline" 
  newline_before_tags : [] 
  preserve_newlines : true 
  quotes : "single"
