Govspeak is our markdown-derived mark-up language.

# Usage

Install the gem

    gem install govspeak

or add it to your Gemfile

    gem "govspeak"

then create a new document

    require 'rubygems'
    require 'govspeak'

    doc = Govspeak::Document.new "^Test^"
    puts doc.to_html

# Extensions

In addition to the [standard Markdown syntax](http://daringfireball.net/projects/markdown/syntax "Markdown syntax"), we have added our own extensions.

## Callouts

</div>
```


### Warning callouts

    %This is a warning callout%

creates a callout with a warning or alert (!) icon

```html
<div role="note" aria-label="Warning" class="application-notice help-notice">

</div>
```

### Example callout

## Steps

Steps can be created similar to an ordered list:

    s1. numbers
    s2. to the start
    s3. of your list

Note that steps need an extra line break after the final step (ie. two full blank lines) or other markdown directly afterwards won't work. If you have a subhead after - add a line break after this.

## Legislative Lists

For lists where you want to specify the numbering and have multiple indent levels.

    $LegislativeList
    * 1. Item 1
    * 2. Item 2
      * a) Item 2a
      * b) Item 2b
        * i. Item 2 b i

    * 3. Item 3
    $EndLegislativeList
    (to indent, add 2 spaces)

## Priority Lists

For lists where you want to specify a number of items to be highlighted as priority.

    $PriorityList:3
    - Item 1
    - Item 2
    - Item 3
    - Item 4
    - Item 5

creates a list with priority items flagged with a class

```html
<ul>
  <li class="primary-item">Item 1</li>
  <li class="primary-item">Item 2</li>
  <li class="primary-item">Item 3</li>
  <li>Item 4</li>
  <li>Item 5</li>
</ul>
```

## Devolved content

    :scotland:content goes here:scotland:
    :london:content goes here:london:
    :wales:content goes here:wales:
    :northern-ireland:content goes here:northern-ireland:
    :england-wales:content goes here:england-wales:

will create a box for the specified locality

```html
<div class="devolved-content england">
  <p class="devolved-header">This section applies to England</p>
  <div class="devolved-body">
    <p>content goes here</p>
  </div>
</div>
```

## Tables

Tables follow the [Kramdown syntax for tables](https://kramdown.gettalong.org/syntax.html#tables) with one addition - table headers can be specified by adding a `#` at the start of the cell. A table header inside the table head will be given a `scope` of `col`; a table header outside will be given a `scope` of `row`.

```markdown
|               |# Column header one |# Column header two |
|---------------|--------------------|--------------------|
|# Row header 1 | Content #1         | Content #2         |
|# Row header 1 | Content #3         | Content #4         |
```

```html
<table>
  <thead>
    <tr>
      <td></td>
      <th scope="col">Column header one</th>
      <th scope="col">Column header two</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">Row header 1</th>
      <td>Content #1</td>
      <td>Content #2</td>
    </tr>
    <tr>
      <th scope="row">Row header 2</th>
      <td>Content #3</td>
      <td>Content #4</td>
    </tr>
  </tbody>
</table>
```

## Barcharts

For when you want a table to be progressively enhanced by Javascript to be
rendered as a bar chart.

    |col|
    |---|
    |val|
    {barchart}

will be rendered as

```html
<table class="js-barchart-table mc-auto-outdent">
  <thead>
    <tr>
      <th>col</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>val</td>
    </tr>
  </tbody>
</table>
```

## Embedded Content

Embedded content allows authors to reference a supporting item of a document by
referencing an id. The details of this content is passed to the publishing
application to govspeak at the time of rendering.

### Button

An accessible way to add button links into content, that can also allow cross domain tracking with [Google Analytics](https://support.google.com/analytics/answer/7372977?hl=en)

This button component uses the component from the [components gem](https://components.publishing.service.gov.uk/component-guide/button) for use in govspeak.

You must use the [link](https://daringfireball.net/projects/markdown/syntax#link) syntax within the button tags.

#### Examples

To get the most basic button.

```
{button}[Continue](https://gov.uk/random){/button}
```

which outputs

```html
<a role="button" class="gem-c-button govuk-button" href="https://gov.uk/random">
  Continue
</a>
```

To turn a button into a ['Start now' button](https://www.gov.uk/service-manual/design/start-pages#start-page-elements), you can pass `start` to the button tag.

```
{button start}[Start Now](https://gov.uk/random){/button}
```

which outputs

```html
<a role="button" class="gem-c-button govuk-button govuk-button--start" href="https://gov.uk/random">
  Start Now
  <svg class="govuk-button__start-icon" xmlns="http://www.w3.org/2000/svg" width="17.5" height="19" viewBox="0 0 33 40" role="presentation" focusable="false"><path fill="currentColor" d="M0 0h13l20 20-20 20H0l20-20z"></path></svg>
</a>
```

You can pass a Google Analytics [tracking id](https://support.google.com/analytics/answer/7372977?hl=en) which will send page views to another domain, this is used to help services understand the start of their users journeys.

```
{button start cross-domain-tracking:UA-XXXXXX-Y}
  [Start Now](https://example.com/external-service/start-now)
{/button}
```

which outputs

```html
<a
  role="button"
  class="gem-c-button govuk-button govuk-button--start"
  href="https://example.com/external-service/start-now"
  data-module="cross-domain-tracking"
  data-tracking-code="UA-XXXXXX-Y"
  data-tracking-name="govspeakButtonTracker"
>
  Start Now
  <svg class="govuk-button__start-icon" xmlns="http://www.w3.org/2000/svg" width="17.5" height="19" viewBox="0 0 33 40" role="presentation" focusable="false"><path fill="currentColor" d="M0 0h13l20 20-20 20H0l20-20z"></path></svg>
</a>
```
