SUPPLESCROLL

scrolling articles to your heart's delight

Supplescroll is a javascript plugin that converts a plain HTML document into an interactive document with auto-generated table-of-contents and easy-to-read figures and references.

It turns this markdown into this interactive webpage.

Features:

Available themes:

Usage

Once the article.md article.md is written, then:

> supplescroll article.md 

Which makes article.html. Open it.

To choose another theme with your choice of output:

> supplescroll -o colorful.html article.md clown

With a plain HTML file article.html article.html:

> supplescroll article.html

Which will overwrite article.html and copy the required files over to that directory.

Write Article with Markdown

supplescroll uses a typical YAML/markdown format to convert your documents into HTML. An example is in article.md:

The format consists of a:

  1. header in YAML
  2. body in markdown

YAML header

The title is the text that goes in the Window title.

The banner string is inserted into the banner part of the page.

The is_rename boolean indicates whether links to references and figures are to be renamed.

Headers

Write the text in markdown, making sure to use proper markdown headers, which will be used to construct the table of contents:

# A Header
## A Secondary Header

Figures

To create a figure, you must escape markdown with a <div> tag, and give the <div> an appropriate id="fig*".

The plain text after the <div> tag serves as a figure label, and this can be differentiated by latter text that is wrapped in <pre> or <code> tags.

It is important to note that if you want to display HTML-code, you need to escape special HTML characters (<, &). You can do this wiht an HTML-escape sanitizer.

Code Blocks. This is to make large blocks of code that the reader might want to look at with the main text. Use <pre> for a multi-line block, and <code> for inline references. These will be wrapped in a scrollable style. Make sure you escape HTML tags. Here's an example:

<div id='fig-code'> 
  Code Fragment Label
  <pre>
  Hello World
  &lt;escaped tag&rt;   </pre>
</div>

which renders as Code Fragment.

Code Fragment
  Hello World
  <escaped tag>  

Images. To insert photos with a label, you can add a label as text before the <img> tag in the figure:

<div id='fig-photo'>
  Photo Label <br>
  <img src='http://boscoh.github.io/supplescroll/photo.jpg'>
</div>

which gives Photo Insert.

Photo Insert

Youtube Embeds. Text before the <img> tag works as a figure label. supplescroll knows how to resize embeds properly:

<div id='fig-youtube'>
  Label to Youtube Video
  <br><br>
  <iframe width="560" height="315" src="//www.youtube.com/embed/Fk5reVYChlo?list=FLnRk0rt9QwA9a_mmCvlfXDw&start=52" frameborder="0" allowfullscreen></iframe>
</div>

which renders as Youtube Embedding.

Youtube Embedding

Figure links

In the main text, links to figures are identified as relative links to #fig*. To link to the above few figures, we can type:

- link to code [](#fig-code),  
- link to photo [](#fig-photo),  
- link to youtube [](#fig-youtube).

which will generate:

Automatic Figure Naming

By default, supplescroll will assign a label to all figures (Figure 1) etc. and references [1] etc. To turn this off, set is_rename: false field in the header (example). And make sure you fill in your preferred text.

References

References are similar to figures, in that you can push references into the third column, and back-links are generated. As such you list all your references in a <div> for a figure, which is illustrated with this code snippet .

Note the references are <a id="ref*"></a> tags that are wrapped by a <div>. This allows the correct placement of the reference back-link at the beginning of the <div>.

In the main text, links to a reference are written:

Thus some text can be liberally sprinkled with a reference to:

- google [](#ref-1)
- github [](#ref-2)
- boscoh [](#ref-3)

Thus some text can be liberally sprinkled with a reference to:

example code for references
<div id="fig-references">
    <h1>References</h1>
    <div class="reference">
        <a id="ref-1"></a>This is the detail to the linked reference, maybe it's a link<a href="http://boscoh.com">boscoh.com</a>
    </div>
    <div class="reference">
        <a id="ref-2"></a>This is the detail to the linked reference, maybe it's a link<a href="http://boscoh.com">boscoh.com</a>
    </div>
    <div class="reference">
        <a id="ref-3"></a>This is the detail to the linked reference, maybe it's a link<a href="http://boscoh.com">boscoh.com</a>
    </div>
</div>
  
REFERENCES

http://google.com - a link to this well-known search engine.
http://github.com - where the source-code is stored.
http://boscoh.com - the website of the author of this package.

Write Article in HTML

Of course, you can just write the html yourself as in article.html article.html, and then run:

> supplescroll article.html light

which will insert references to the files:

To ensure supplescroll processes the correct items, in your HTML file, you should:

  1. (optionally) include the banner through a top level <div id="banner">.

  2. use <h*> tags for headers, which will all be incorporated into the table-of-contents.

  3. name figures with <div id="fig*">.

  4. name links to figures as <a href="fig*"> and name links to references as <a href="ref*">.

  5. create a figure just to hold references <div id="fig-references">

  6. put references in the fig-references as

     <div>
       <a id="ref-1"></a> My reference 
     </div>
    
  7. (optionally) suppress figure/reference renmaing naming by adding

     <script> window.is_rename = false </script>
    

Theme it Yourself

If you are familiar with CSS then you can simply change the CSS in any of the themes, and rename the CSS, ensuring the link in the HTML file is also changed. Then send me the CSS!
