(partially implemented)

for each markdown article object, you are able to access these properties in template:

global {
  config {
    siteTitle: "xxxxx",
    siteUrl: "https://xxx.com/",
    siteMenus: [{ menuName: "xx", menuLoc: "/xx/xxx" }]
  },
  partials {
    xx1.html: "xxx<xx>xxxx</xx>xxx",
    xx2.html: "xxxx"
  }
}
this {
    title: "xxx",
    date: "xxxx-xx-xx",
    category: "yy",
    template: "xx.html",
    relLink: "/xx/xx.html",
    content: "blah blah blah..."
    // and something else in the meta data of the post markdown file
}

The partials field in global is the raw partial file content. You normally use [- partial xx.html -] to employ them instead of [- global.partials.xx.html -] because the latter one wouldn’t work.
The template field in this is designed for choosing its corresponding template. If there is no template specified in Markdown metadata, it will be default to post.html.
Any entry that extra-added to Markdown metadata will be available to template accessing.

as for the index.html template, it has some different properties:

global: {
  config: {
    siteTitle: "xxxxx",
    siteUrl: "https://xxx.com/",
    siteMenus: [{ name: "xx", loc: "/xx/xxx" }]
  },
  partials: {
    xx1.html: "xxx<xx>xxxx</xx>xxx",
    xx2.html: "xxxx"
  }
}
this: {
  posts: [
    // each post object has complete properties just as accessings in `post.html`
    {
      title: "xxx",
      date: "xxxx-xx-xx",
      category: "yy",
      template: "xx.html",
      relLink: "/xx/xx.html",
      content: "blah blah blah..."
    },
    {
      title: "xxxx",
      date: "xxxx-xx-xx",
      category: "yyyy",
      template: "xx.html",
      relLink: "/xx/xx2.html",
      content: "blah blah blah..."
    }
  ],
  categories: [
    {
      cateName: "yy" // name of the category
      posts [
        {
          title: "xxx",
          date: "xxxx-xx-xx",
          category: "yy",
          template: "xx.html",
          relLink: "/xx/xx.html",
          content: "blah blah blah..."
        }
      ]
    },
    {
      cateName: "yyyy"
      posts: [
        {
          title: "xxxx",
          date: "xxxx-xx-xx",
          category: "yy",
          template: "xx.html",
          relLink: "/xx/xx2.html",
          content: "blah blah blah..."
        }
      ]
    }
  ]
}
