# A Hugo Theme Using HTML5 Semantics and IndieWeb Integration

This theme is a fork of [My Basic Theme](https://git.thecorams.net/kevin/basic-theme),
adding additional HTML5 semantics, a more responsive site design, and
[IndieWeb](https://indieweb.org/) [microformats](http://microformats.org/wiki/Main_Page).

## Getting Started

Follow the [Hugo Quickstart](https://gohugo.io/getting-started/quick-start/)
instructions on how to install Hugo, create a site, and install a theme.
Installing the theme as a git submodule is the preferred way.

```
git submodule add https://git.thecorams.net/kevin/semantic-indieweb.git themes/semantic-indieweb
```

### Example Site

The theme includes an example site to give a quick way to see how the theme
looks and behaves.

```
cd exampleSite
hugo serve [ -D ] --themesDir ../..
```

Most of the sample posts are intentionally set `draft: true` to allow for
testing few posts vs many posts.

## Configuration

The footer layout file uses Hugo's `markdownify` pipe to display the `copyright`
configuration setting, providing support both for HTML character escape
sequences such as `©` as well as markdwn formatting and links.

Note: Hugo versions 0.60.0 and up will have restrictions on using embedded HTML,
including escape secquences, unless the Goldmark renderer is configure with
`unsafe = true`.

### `subtitle` parameter

Setting the `subtitle` parameter adds a secondary header underneath the `title`
in the site header.

```toml
[params]
  subtitle = "A sub-title for your site"
```

### `mainSections` parameter

Setting the `mainSections` parameter restricts the pages that appear on the
homepage.

```toml
[params]
  mainSections = ["posts"]

```

### IndieWeb / IndieAuth Identities

The theme includes support for adding `rel="me"` links to the HTML head of
every page. Such links help tie together the sites one owns, as well as
provide support for [IndieAuth](https://www.w3.org/TR/indieauth/)
authentication.

These links can be configured by including one or more `params.Identity`
blocks:

```toml
  [[params.Identity]]
    type = "some-type"
    value = "identity"
    authn = false
```

The current set of known types are:

- Email
  - The `value` should be a valid e-mail address which could be used for
    IndieAuth authentication
- GitHub
  - The `value` should be a valid GitHub user name
- GitLab
  - The `value` should be a valid GitLab user name
- Twitter
  - The `value` should be a valid Twitter user name
- MicroBlog
  - The `value` should be a valid MicroBlog user name
- PGP
  - The `value` should be a valid URL to the site owner's public PGP key

The IndieAuth standard allows the site author to specify which of the
`rel="me"` links should be preferred for authentication. If the `authn`
parameter for an identity is set to `true`, the link will be generated
as `rel="me authn"`. As explained on
[https://indielogin.com/setup](https://indielogin.com/setup):

> If any of your `rel="me"` links also include `authn` in the list of rels,
> then IndieLogin.com will only use the links with `authn`, and will no longer
> consider your plain `rel="me"` links as authentication options.

### IndieWeb h-card

The theme includes a "card" for displaying the site author's photo (or a logo
image for the site), the author's name, and the author's rough location. The
data in the card is marked up with [h-card](http://microformats.org/wiki/h-card)
microformats, for integration with IndieWeb-aware sites and tools.

```toml
  # Configuration Parameters for IndieWeb h-card
  [params.Card]
    Author = "Site Author Name"
    Photo = "images/picture-o.svg"
    Locality = "City/Town/Village"
    Region = "State/County/Province"
    Country = "Country Name"
```

#### Social Network Links

The theme will render a ribbon of icon links to other sites beneath the
author's location information. The theme comes bundled with 
[Fork Awesome v1.1.7](https://forkaweso.me/Fork-Awesome/). Any of the icons
provided by Fork Awesome can easily be used. For example, to add a link to
one's Twitter profile, add a configuration block that uses the Fork Awesome
twitter icon:

```toml
  [[params.Social]]
    profile = "https://twitter.com/twitter-user-name"
    icon = "fa fa-twitter"
```

The icon/font library being used can be overriden by creating a site-specific
`icons.html` partial. Font Awesome, Fork Awesome, Fontello, and many other
icon/font libraries all support embedding an icon using similar CSS class names,
which can be used in the `icon = "...."` configuration.

In addition to the `profile` and `icon` pairs, there is also support for e-mail
links and PGP key file links with the PGP fingerprint as a toolip:

```toml
  [[params.Social]]
    email = "email@example.com"
    icon = "fa fa-envelope-o"

  [[params.Social]]
    publicKey = "pgp_key_file.txt"
    fingerprint = "AAAA BBBB CCCC DDDD"
    icon = "fa fa-key"
```

### Configuring Webmentions

[Webmention](https://www.w3.org/TR/webmention/) and/or 
[Pingback](http://www.hixie.ch/specs/pingback/pingback) support can easily be
configured by including the endpoint URL:

```toml
  [params]
    Webmention = "https://example.org/webmention"
    Pingback = "https://example.org/pingpack"
```

## Theme Organization

### Semantic Content Organization

The chrome of the theme page organization is as follows:

```html
<html>
<head>
    <title>Site Title</title>
</head>
<body>
    <header>
        <hgroup>
          <h1>Site Title</h1>
          <h2>Site Sub-title</h2>
        </hgroup>
        <nav>
            <!-- Site Navigation/Menu: links to pages that are part of -->
            <!-- the "main" menu                                       -->
        </nav>
    </header>
    <main>
        <header>
            <h1>Content Title</h1>
            <nav>
                <!-- Content Navigation/Menu: a place holder for a       -->
                <!-- content specific menu, such as a list of blog posts -->
                <!-- based on publication date. Not yet implemented.     -->
            </nav>
        </header>
        <section>
            <!-- The page content. For list sections, this is where the  -->
            <!-- the list of pages goes. For single pages, this is where -->
            <!-- the content of the page markdown file goes.             -->
        </section>
        <footer>
            <!-- The page footer. For list sections, this is where the   -->
            <!-- pagination controls can go. For single pages, this is   -->
            <!-- where auther attribution and/or prev/next page controls -->
            <!-- could go.                                               -->
        </footer>
    </main>
    <footer>
        <!-- The Site Footer, for copyright information etc. -->
    </footer>
</body>
</html>
```

If the content pages use `##` as their largest heading, this will result
in document outlines structured as:

1. Site Title
   1. Site Sub-title
2. Content Title
   1. Header from Content
      1. Sub-header from content
   2. Second Header from Content

### Hugo Templating

The template layout files make heavy use of Hugo's
[base and block constructs](https://gohugo.io/templates/base/), as can be seen
in [baseof.html](layouts/_default/baseof.html).

#### title

This block is used for generating the `<title>....</title>` markup for the
rendered page and defaults to using the `title` configuration from `comfig.toml`.
The [list](layouts/_default/list.html) and [single](layouts/_default/single.html)
templates add the page title, to facilitate generating a unique title for every
page.

#### site-header

This block is for providing a site banner that will appear at the top of every page,
and matches with the primary `<header>...</header>` definition from the semantic
organization, above.

The default site-header block displays the [header.html](layouts/partials/header.html)
partial.

#### site-menu

This block is for providing a site-level navigation, which also appears at the
top of every page. It renders in the `<nav>...</nav>` block within the primary
header.

The default site-meny block displays the [site-menu](layouts/partials/site-menu.html)
partial.

#### content-header

This block is for providing a header for the specific page, matching with the
header block inside the `<main>....<\main>` definition from the semantic
organization. The [list](layouts/_default/list.html) and
[single](layouts/_default/single.html) templates display the page title as
a `<h1>...</h1>` level header.

#### content-menu

This block is for providing navigation menu(s) for the main content, matching
with the `<nav>...</nav>` block inside the main header. The block is currently
a place holder, with no default implementation.

#### content

This block is for the content of the page.

For [list](layouts/_default/list.html) pages, the content from the section's
`_index.md` will be rendered, followed by a list of all of the pages within
the section, using the [summary](layouts/_default/summary.html) template.

For [single](layouts/_default/single.html) pages, the page content will be
rendered inside an `<article>...</article>` block element.

#### content-footer

This block provides a footer for the page, which renders within the
`<footer></footer>` block at the end of the `<main></main>` section.

The default content-footer blocks for the homepage and for list pages
implement pagination controls to show the content summaries a page at a time.

The default content-footer block for single pages displays previous and/or
next in section links.

#### footer

This block is for the site footer that appears at the end of every pages.

The default footer block displays the [footer.html](layouts/partials/footer.html)
partial.
