Simple Public License (SimPL-2.0)
=================================
Preamble
--------
This Simple Public License 2.0 (SimPL-2.0 for short) is a plain language
implementation of GPL 2.0. The words are different, but the goal is the
same - to guarantee for all users the freedom to share and change
software. If anyone wonders about the meaning of the SimPL, they should
interpret it as consistent with GPL 2.0.
Simple Public License (SimPL) 2.0
=================================
The SimPL applies to the software's source and object code and comes
with any rights that I have in it (other than trademarks). You agree to
the SimPL by copying, distributing, or making a derivative work of the
software.
You get the royalty free right to:
- Use the software for any purpose;
- Make derivative works of it (this is called a "Derived Work");
- Copy and distribute it and any Derived Work.
If you distribute the software or a Derived Work, you must give back to
the community by:
- Prominently noting the date of any changes you make;
- Leaving other people's copyright notices, warranty disclaimers, and
license terms in place;
- Providing the source code, build scripts, installation scripts, and
interface definitions in a form that is easy to get and best to
modify;
- Licensing it to everyone under SimPL, or substantially similar terms
(such as GPL 2.0), without adding further restrictions to the rights
provided;
- Conspicuously announcing that it is available under that license.
There are some things that you must shoulder:
- You get NO WARRANTIES. None of any kind;
- If the software damages you in any way, you may only recover direct
damages up to the amount you paid for it (that is zero if you did
not pay anything). You may not recover any other damages, including
those called "consequential damages." (The state or country where
you live may not allow you to limit your liability in this way, so
this may not apply to you);
The SimPL continues perpetually, except that your license rights end
automatically if:
- You do not abide by the "give back to the community" terms (your
licensees get to keep their rights if they abide);
- Anyone prevents you from distributing the software under the terms
of the SimPL.
License for the License
-----------------------
You may do anything that you want with the SimPL text; it's a license
form to use in any way that you find helpful. To avoid confusion,
however, if you change the terms in any way then you may not call your
license the Simple Public License or the SimPL (but feel free to
acknowledge that your license is "based on the Simple Public License").

The directory structure and templates provide the majority of the
configuration for a site. In fact a config file isn't even needed for many websites
since the defaults used follow commonly used patterns.
The following is an example of a config file with the default values
{
"SourceDir" : "content",
"LayoutDir" : "layouts",
"PublishDir" : "public",
"BuildDrafts" : false,

The front matter is one of the features that gives Hugo it's strength. It enables
you to include the meta data of the content right with it. Hugo supports a few
different formats. The main format supported is JSON. Here is an example:
{
"Title": "spf13-vim 3.0 release and new website",
"Description": "spf13-vim is a cross platform distribution of vim plugins and resources for Vim.",
"Tags": [ ".vimrc", "plugins", "spf13-vim", "vim" ],
"Pubdate": "2012-04-06",
"Categories": [ "Development", "VIM" ],
"Slug": "spf13-vim-3-0-release-and-new-website"
}
### Variables
There are a few predefined variables that Hugo is aware of and utilizes. The user can also create
any variable they want to. These will be placed into the `.Params` variable available to the templates.
#### Required
**Title** The title for the content. <br>
**Description** The description for the content.<br>
**Pubdate** The date the content will be sorted by.<br>
**Indexes** These will use the field name of the plural form of the index (see tags and categories above)
#### Optional
**Draft** If true the content will not be rendered unless `hugo` is called with -d<br>
**Type** The type of the content (will be derived from the directory automatically if unset).<br>
**Slug** The token to appear in the tail of the url.<br>
*or*<br>
**Url** The full path to the content from the web root.<br>
*If neither is present the filename will be used.*

Hugo uses markdown files with headers commonly called the front matter. Hugo respects the organization
that you provide for your content to minimize any extra configuration, though this can be overridden
by additional configuration in the front matter.
## Organization
In Hugo the content should be arranged in the same way they are intended for the rendered website.
Without any additional configuration the following will just work.
.
└── content
├── post
| ├── firstpost.md // <- http://site.com/post/firstpost.html
| └── secondpost.md // <- http://site.com/post/secondpost.html
└── quote

Because Hugo uses markdown for it's content format, it was clear that there's a lot of things that
markdown doesn't support well. This is good, the simple nature of markdown is exactly why we chose it.
However we cannot accept being constrained by our simple format. Also unacceptable is writing raw
html in our markdown every time we want to include unsupported content such as a video. To do
so is in complete opposition to the intent of using a bare bones format for our content and
utilizing templates to apply styling for display.
To avoid both of these limitations Hugo has full support for shortcodes.
### What is a shortcode?
A shortcode is a simple snippet inside a markdown file that Hugo will render using a template.
Short codes are designated by the opening and closing characters of '{{&#37;' and '%}}' respectively.
Short codes are space delimited. The first word is always the name of the shortcode. Following the
name are the parameters. The author of the shortcode can choose if the short code
will use positional parameters or named parameters (but not both). A good rule of thumb is that if a
short code has a single required value in the case of the youtube example below then positional
works very well. For more complex layouts with optional parameters named parameters work best.
The format for named parameters models that of html with the format name="value"
### Example: youtube
*Example has an extra space so Hugo doesn't actually render it*
{{ % youtube 09jf3ow9jfw %}}
This would be rendered as
<div class="embed video-player">
<iframe class="youtube-player" type="text/html"
width="640" height="385"
src="http://www.youtube.com/embed/09jf3ow9jfw"
allowfullscreen frameborder="0">
</iframe>
</div>
### Example: image with caption
*Example has an extra space so Hugo doesn't actually render it*
{{ % img src="/media/spf13.jpg" title="Steve Francia" %}}
Would be rendered as:
<figure >
<img src="/media/spf13.jpg" />
<figcaption>
<h4>Steve Francia</h4>
</figcaption>
</figure>
### Creating a shortcode
All that you need to do to create a shortcode is place a template in the layouts/shortcodes directory.
The template name will be the name of the shortcode.
**Inside the template**
To access a parameter by either position or name the index method can be used.
{{ index .Params 0 }}
or
{{ index .Params "class" }}
To check if a parameter has been provided use the isset method provided by Hugo.
{{ if isset .Params "class"}} class="{{ index .Params "class"}}" {{ end }}

Hugo takes a single directory and uses it as the input for creating a complete website.
Hugo has a very small amount of configuration, while remaining highly customizable.
It accomplishes by assuming that you will only provide templates with the intent of
using them.
An example directory may look like:
.
├── config.json
├── content
| ├── post
| | ├── firstpost.md
| | └── secondpost.md
| └── quote
| | ├── first.md
| | └── second.md
├── layouts
| ├── chrome
| | ├── header.html
| | └── footer.html
| ├── indexes
| | ├── category.html
| | ├── post.html
| | ├── quote.html
| | └── tag.html
| ├── post
| | ├── li.html
| | ├── single.html
| | └── summary.html
| ├── quote
| | ├── li.html
| | ├── single.html
| | └── summary.html
| ├── shortcodes
| | ├── img.html
| | ├── vimeo.html
| | └── youtube.html
| ├── index.html
| └── rss.xml
└── public
This directory structure tells us a lot about this site:
1. the website intends to have two different types of content, posts and quotes.
2. It will also apply two different indexes to that content, categories and tags.
3. It will be displaying content in 3 different views, a list, a summary and a full page view.
Included with the repository is an this example site ready to be rendered.

Hugo uses the excellent golang html/template library for it's template engine. It is an extremely
lightweight engine that provides a very small amount of logic. In our
experience that it is just the right amount of logic to be able to create a good static website
This document will not cover how to use golang templates, but the [golang docs](http://golang.org/pkg/html/template/)
provide a good introduction.
### Template roles
There are 5 different kinds of templates that Hugo works with.
#### index.html
This file must exist in the layouts directory. It is the template used to render the
homepage of your site.
#### rss.xml
This file must exist in the layouts directory. It will be used to render all rss documents.
The one provided in the example application will generate an ATOM format.
*Important: Hugo will automatically add the following header line to this file.*
<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
#### Indexes
An index is a page that list multiple pieces of content. If you think of a typical blog, the tag
pages are good examples of indexes.
#### Content Type(s)
Hugo supports multiple types of content. Another way of looking at this is that Hugo has the ability
to render content in a variety of ways as determined by the type.
#### Chrome
Chrome is simply the decoration of your site. It's not a requirement to have this, but in practice
it's very convenient. Hugo doesn't know anything about Chrome, it's simply a convention that you may
likely find beneficial. As you create the rest of your templates you will include templates from the
/layout/chrome directory. I've found it helpful to include a header and footer template
in Chrome so I can include those in the other full page layouts (index.html, indexes/ type/single.html).
### Adding a new content type
Adding a type is easy.
**Step 1:**
Create a directory with the name of the type in layouts.Type is always singular. *Eg /layouts/post*.
**Step 2:**
Create a file called single.html inside your directory. *Eg /layouts/post/single.html*.
**Step 3:**
Create a file with the same name as your directory in /layouts/indexes/. *Eg /layouts/index/post.html*.
**Step 4:**
Many sites support rendering content in a few different ways, for instance a single page view and a
summary view to be used when displaying a list of contents on a single page. Hugo makes no assumptions
here about how you want to display your content, and will support as many different views of a content
type as your site requires. All that is required for these additional views is that a template
exists in each layout/type directory with the same name.
For these, reviewing this example site will be very helpful in order to understand how these types work.

Make sure either hugo is in your path or provide a path to it.
$ hugo --help
usage: hugo [flags] []
-b="": hostname (and path) to the root eg. http://spf13.com/
-c="config.json": config file (default is path/config.json)
-d=false: include content marked as draft
-h=false: show this help
-k=false: analyze content and provide feedback
-p="": filesystem path to read files relative from
-w=false: watch filesystem for changes and recreate as needed
-s=false: a (very) simple webserver
-p="1313": port for webserver to run on
## Common Usage Example:
The most common use is probably to run hugo with your current
directory being the input directory.
$ hugo
> X pages created
> Y indicies created
If you are working on things and want to see the changes
immediately, tell Hugo to watch for changes.
<br>
**It will
recreate the site faster than you can tab over to
your browser to view the changes.**
$ hugo -p ~/mysite -w
Watching for changes. Press ctrl+c to stop
15 pages created
0 tags created
Hugo can even run a server and create your site at the same time!
$hugo -p ~/mysite -w -s
Watching for changes. Press ctrl+c to stop
15 pages created
0 tags created
Web Server is available at http://localhost:1313
Press ctrl+c to stop

Hugo makes a set of values available to the templates. Go templates are context based. The following
are available in the context for the templates.
**.Title** The title for the content. <br>
**.Description** The description for the content.<br>
**.Keywords** The meta keywords for this content.<br>
**.Date** The date the content is published on.<br>
**.Indexes** These will use the field name of the plural form of the index (see tags and categories above)<br>
**.Permalink** The Permanent link for this page.<br>
**.FuzzyWordCount** The approximate number of words in the content.<br>
**.RSSLink** Link to the indexes' rss link <br>
Any value defined in the front matter, including indexes will be made available under `.Params`.
Take for example I'm using tags and categories as my indexes. The following would be how I would access them:
**.Params.Tags** <br>
**.Params.Categories** <br>
Also available is `.Site` which has the following:
**.Site.BaseUrl** The base URL for the site as defined in the config.json file.<br>
**.Site.Indexes** The names of the indexes of the site.<br>
**.Site.LastChange** The date of the last change of the most recent content.<br>
**.Site.Recent** Array of all content ordered by Date, newest first<br>
