  - name: categories
    desc: >-
      The specified categories for this post. If a post has multiple categories, Jekyll will create

      double slashes in the URLs, so if no categories are present, it will ignore this.      
  - name: slugified_categories
    intro_ver: "4.1"
    desc: >-
      The specified categories for this post but <em>slugified</em>. If a category is a composite of
      multiple words, Jekyll will downcase all alphabets and replace any non-alphanumeric character
      with a hyphen. (e.g. <code>"Work 2 Progress"</code> will be converted into
      <code>"work-2-progress"</code>). If a post has multiple categories, Jekyll will create
      a hierarchy (e.g. <code>/work-2-progress/category2</code>). Also Jekyll automatically parses
      out double slashes in the URLs, so if no categories are present, it will ignore this.      
  - name: output_ext

  - name: weekdate

    note: "<code>W</code> will be prefixed to the value of <code>:week</code>"
  - name: none
    format: "/:categories/:title:output_ext"

types:
  documents:
    - name: collection
      desc: >-
        Label of the containing collection.        
    - name: path
      desc: >-
        Path to the document relative to the collection's directory, including base filename of the document.
        However, does not include the file extension.        
    - name: name
      desc: >-
        The document's base filename but slugified: downcased and every sequence of non-alphanumeric character
        (including spaces) replaced by a hyphen.        
    - name: title
      desc: >-
        Takes on the value of front matter key <code>slug</code> if defined for the document. Otherwise takes
        on the string value generated from the document's base filename by piping through the <code>slugify</code>
        filter method with <code>pretty</code> option.<br/>
        Regardless of the value taken, the case of the alphabets are preserved instead of being replaced with
        lowercase counterparts.        
    - name: output_ext
      desc: >-
        Extension of the output file. (Included by default and usually unnecessary.)        
  pages:
    - name: path
      desc: >-
        Path between the source directory and the base filename of the page.        
    - name: basename
      desc: >-
        The page's base filename.        
    - name: output_ext
      desc: >-
        Extension of the output file. (Included by default and usually unnecessary.)
