WMD: The Wysiwym Markdown Editor


WMD is a JavaScript based code editor for the Markdown formatting language. It includes a Markdown interpreter – Showdown – for live preview and output of the Markdown generated HTML.

This is a fork of WMD for ChiperSoft Systems & NFY Interactive designed for use in CMS engines. It was forked from the Open Library fork of WMD, which was in turn forked from the Stackoverflow fork.

Major Changes from Open Library Revision

  • Extended showdown to support a series of Markdown extensions:
    • Link urls that start with ! are opened in a new window
    • Text wrapped with double carets is made superscript (ex: ^^this text is superscripted^^)
    • Text wrapped with double commas is made subscript (ex: ,,this text is subscripted,,)
    • Text wrapped with double tildes is made strikethrough (ex: ~~this text is struck~~)
    • (c), (r), (tm), -- and ... are converted into their respective html entities.
    • Lines prefixed with "->" are right aligned. Lines also postfixed with "<-" are center aligned.
  • Several ascii characters that may produce encoding issues (such as curled quotes) are converted into entities
  • Removed top level frame pollution, forcing WMD to run only in its own document.
  • Removed the automatic conversion from Markdown to HTML when the form is submitted.
  • Removed the automatic addition of http:// to image urls, preventing the entry of relative addresses.
  • Numerous bug fixes to both WMD and Showdown
