# A Superscript Extension for Markdown

This extension adds the ability to add superscripts to Markdown documents.


## Usage

To superscript something, place a carat symbol, '^', before and after the
text that you would like in superscript:  6.02 x 10^23^
The '23' in this example will be superscripted.  See below.

Examples:

    >>> import markdown
    >>> md = markdown.Markdown(extensions=['superscript'])
    >>> md.convert('This is a reference to a footnote^1^.')
    u'<p>This is a reference to a footnote<sup>1</sup>.</p>'
    
    >>> md.convert('This is scientific notation: 6.02 x 10^23^')
    u'<p>This is scientific notation: 6.02 x 10<sup>23</sup></p>'
    
    >>> md.convert('This is scientific notation: 6.02 x 10^23. Note lack of second carat.')
    u'<p>This is scientific notation: 6.02 x 10^23. Note lack of second carat.</p>'
    
    >>> md.convert('Scientific notation: 6.02 x 10^23. Add carat at end of sentence.^')
    u'<p>Scientific notation: 6.02 x 10<sup>23. Add a carat at the end of sentence.</sup>.</p>'

Paragraph breaks will nullify superscripts across paragraphs. Line breaks
within paragraphs will not.

Drop superscript.py into your /site-packages/markdown/extensions/ directory.


## Calling from Command Line

markdown.py FILENAME.md -x superscript --file=OUTPUTFILE.html

Where:

* FILENAME.md = valid Markdown file to convert

* '-x superscript' calls the extension

* OUTPUTFILE.html = the resulting HTML conversion of the Markdown file
