A Markdown extension for superscripting text.
# A Superscript Extension for Markdown
This extension adds the ability to add superscripts to Markdown documents.
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.
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
